How Long Does THC Stay in Your Blood?

Cannabinol   (CBN) is one of the components that make up cannabis (marijuana) – the so-called cannabinoid. In total, more than a hundred cannabinoids are known, but it is with cannabinol, or rather tetrahydrocannabinol (THC), that the psychoactive properties of marijuana are associated. In the body, THC disintegrates very quickly, and cannabinol is the product of its decay. Young cannabis does not contain CBN at all or only small amounts. Old hemp stored in inappropriate conditions contains a higher concentration of CBN, which is formed as a result of atmospheric air or high temperature. Cannabinol, known mainly for its hypnotic properties, also has many other beneficial health effects.

How cannabinol is formed

Cannabiferic acid (CBGA) is the precursor of both CBN and all other cannabinoids. Under the influence of enzymes contained in cannabis with CBGA, 3 important cannabinoic acids are formed: cannabichromic acid (CBCA), cannabidic acid (CBDA) and tetrahydrocannabinolic acid (THCA). All these acids under the influence of heat or ultraviolet radiation and turn into neutral compounds.

Under the influence of oxygen contained in atmospheric air, as a result of the oxidation process, THC is degraded to cannabinol.

Thus, cannabinol (CBN) is a decomposition product of THC, which occurs when exposed to oxygen or high temperature.

The effect of cannabinol on humans

CBN, compared with THC, has a much weaker psychoactive effect. The result of his actions may be dizziness. Despite these potentially negative effects, this cannabinoid has many beneficial properties. Cannabinol is known for its hypnotic and sedative effects.

In appropriate quantities, it has the same effect as commonly used hypnotics – often without the risk of dependence.

Also, cannabinol has:

  • antibacterial,
  • anti-inflammatory,
  • analgesic properties
  •  stimulates the immune system
  • reduces intraocular pressure in patients with glaucoma,
  •  thanks to anticonvulsant activity – helps patients with epilepsy,
  • it also stimulates bone growth, which can be used to treat osteoporosis.

Use in medicine

The beneficial properties of cannabis are used in medicine in the treatment of cancer patients, HIV-infected patients, to relieve muscle pain in patients with multiple sclerosis, stroke patients, etc. Unfortunately, attempts to synthesize cannabinoid for medical purposes, devoid of side effects, have not justified themselves. The resulting synthetic cannabis was even more harmful than natural. However, scientists do not leave hopes to create effective drugs for the treatment of many diseases by cannabis.

Effects of cannabinol

When using marijuana arise:

  • synesthesia, such as seeing sounds,
  • experiences are accompanied by euphoria,
  • increased self-esteem
  • relaxing
  • loss of self-control
  • a sense of aggravation of feelings and a better understanding of the world,
  • philosophizing,
  • weaknesses and
  • paroxysmal laughter.

Sometimes the effect of smoking marijuana – drowsiness and excessive sedative effect.

The adverse effect is:

  • weakening of memory
  • visual-motor coordination disorder,
  • reduced attention span
  • deterioration of automatism.

The weakening of muscle strength with a fluidity of movements and slower response time leads to a decrease in psychophysical fitness.

Cannabinol poisoning

Sometimes marijuana intoxication may occur, the symptoms of which are:

  • psychotic intoxication
  • accelerated momentum
  • increase in pressure
  • bronchial dilatation,
  • irritation of the mucous membranes of the respiratory tract,
  • conjunctivitis,
  • a headache,
  • fever,
  • dryness of the oral mucosa,
  • hunger.

Symptoms after poisoning can manifest as visual and auditory hallucinations, depersonalization, derealization, persecution mania, changes in the body pattern, anxiety, fear, confusion, and insomnia. The psychotic symptoms caused by smoking marijuana usually go away after a few days.


The most common effects of smoking marijuana are a sore throat, bronchitis, and asthma. Menstrual disorders occur in women who smoke regularly, and testosterone production is impaired in men. Children of mothers who smoke marijuana have less weight at birth than non-smoking children. Also, weed smokers are more susceptible to injuries, for example, due to traffic accidents, because cannabinol weakens reflexes.

Kanabinol causes psychological dependence.

Symptoms of marijuana dependence:

  • sleep disturbances
  • apathy, lack of motivation to action,
  • limited interpersonal contact,
  • impaired concentration and memory
  • impaired learning ability
  • magical and torn thinking,
  • impairment of logical thinking skills
  • a weakening of intuitive behavior
  • emaciation,
  • chronic laryngitis and bronchitis,
  • bouts of coughing.

Longer smoking of cannabis leads to the formation of an apathetic-abulistic syndrome, which manifests itself in idleness, emotional indifference and decreased interest. Extremely, teens who smoke marijuana can isolate themselves from society and stop learning.

Cannabinol test (THC)


Cannabinol (THC) is associated with tests that help determine cannabis use. Such analyzes are usually carried out when applying for a job, before being drafted into the army, for work in the police, public institutions or in road traffic accidents, to determine driving under the influence of narcotic drugs.
Cannabinol is detected in urine, saliva, blood (rarely) or hair.

What do the test results mean

Test results can vary depending on age, gender, medical history, the method used for the test, and other things.
A positive result can confirm the use of marijuana by a person in the recent past. The test for marijuana in the urine will be positive if the amount of THC in the sample is more than 50 ng per milliliter (ng/ml).

If a person uses marijuana, but the test is negative, this may be because the amount of cannabinol in the sample is below this level. Verification can be performed by a more sensitive method if the screening test is positive. This is done to ensure that the result was not caused by a drug or other substance affecting the test.
Urine tests cannot show the exact day or hour when marijuana was last used.
How long cannabinol remains in the body after smoking marijuana? It depends on the frequency of marijuana use and the time when the test is conducted.

Detection of THC in saliva

It is possible to detect the presence of THC in saliva for a very short time. Pharmacy tests detect the presence of cannabinol in saliva within 72 hours after smoking marijuana or hashish.

Blood THC Detection

In the blood, THC (cannabinol) can be detected:

  • with moderate smoking up to 2-3 days after use,
  • with daily smoking up to 2 weeks after consumption.

Detection of THC in the hair

THC appears in the hair one week after the last smoking and remains there for the last 90 days. This means that if you smoked in the last three months, the result would be positive. This testing method is usually inaccurate, because sometimes cannabinol does not penetrate the hair follicle, or vice versa can penetrate the hair if the person was just in a room where someone smoked marijuana. Therefore, this test is rarely used.

Detection of THC in the urine

In the urine, the detection of THC also depends on how often the drug is used:

  • with a single random admission of THC in the urine can be detected up to 3 days,
  • with frequent smoking – up to 10 days,
  • with very frequent and prolonged smoking, cannabinol can be detected in the urine up to 21-27 days after the last use.

The most popular methods for analyzing THC (tetrahydrocannabinol) are tests of urine or personal use items.

How cannabinol urine test is performed
The test should be carried out on a urine sample taken in a special container. Particular attention has the exception of the possibility of sample substitution. Therefore, immediate testing is recommended.
The test result is not affected by the time of day, but it is important that the sample is not stored in the refrigerator.

Before a person undergoing tests begins urination, he must thoroughly wash his hands and clean his nails. There are many ways to influence the result of falsification of the test, for example, adding a minimum amount of neutralizing substances in the urine.

TGC test for personal items

If there is a suspicion that the child or someone from the family uses a drug, do not go to the laboratory. There are new methods for checking suspicion.
All you need to do is buy a TGC test for personal items. According to the instructions, the strip in the test should be wiped off with some object to be checked (it can be a key, mobile phone, jewelry), and then immerse it in a special reagent – liquid attached to the package. After 5 minutes, red lines appear on the strip, indicating the detection of the wanted psychoactive substances.

Is it possible to deceive the test for the presence of THC

People who take drugs find many homemade ways to falsify the test. Among the inefficient household methods, for example, drinking large amounts of water before testing or neutralizing urine with citric acid.

If you smoke a lot, unfortunately, there is no good news for you. In this case, the test will not fail.

If you smoke only occasionally, you can influence the result, given that standard tests based on testing urine samples are highly prone to dilution.

The most effective way to disrupt the results of such a test is to drink plenty of fluids, especially cranberry juice. Of course, the most reliable method is to bind to a given time frame for the natural elimination of THC from the body.

How much marijuana comes out of human urine

Significant changes in biochemical processes in the human body are an accompanying factor in drug use, including marijuana.

Through laboratory research, it is possible to identify metabolites that are formed in the body due to the entry into the reaction of various enzymes with cannabis.

The question of how much grass is kept in the urine arises when a person is preparing to pass tests for the detection of narcotic substances in the body. There is no clear time frame for marijuana urine.

This is influenced by many factors:

  • An individual feature of the body and metabolic rate.
  • Man’s lifestyle.
  • Physical activity.
  • Food features.
  • Hereditary quality.
  • Body weight (obesity cannabis accumulates in adipose tissue).
  • Duration and regular use of drapes.

It is very important to know what kind of marijuana and how it was used. Laboratory testing of urine for cannabinoids is an effective way to detect marijuana.

Thanks to him, it is possible to determine even a one-time use of the drape two to three weeks before the analysis. The advantages of determining narcotic drugs in the human body by urinalysis are:

  1. Taking material for analysis outside the laboratory. Perhaps at home.
  2. The uselessness of special knowledge and training in the collection of material.
  3. High degree of veracity of results.

The main thing is to use sterile containers that are purchased at any pharmacy. After urination, it is necessary to tightly close the container with a special lid. If it is not possible to immediately send the material to the study, the urine can be stored in the refrigerator for 36 hours. The analysis itself is carried out by several methods:

  • Immunochromatographic method – done within fifteen minutes using special strips to identify cannabinoids. The disadvantage of this method is that it does not provide the quantitative presence of marijuana metabolites.
  • Chemistry-toxicological method – the exact method that is used even in court proceedings. Differs in high cost. Such research is carried out throughout the day.

How long does marijuana out of the blood

Hemp refers to psychotropic substances that are composed of tetrahydrocannabinol. This metabolite determines the presence of marijuana in the blood. Such an analysis is not popular, as in the blood metabolites of drape stay only 2-3 days.

In the case of constant use of cannabis, THC is not eliminated at all and leads to a decline in human health and brain activity. Therefore, if you have to donate blood for laboratory testing, it is not recommended to use marijuana 3-4 days before the analysis.

And it is better, of course, not to consume the drape at all, then it will not be necessary to worry about the result of the research and for your health.

What is marijuana?

Marijuana or cannabis (the official name) is a psychoactive substance of plant origin derived from cannabis.

The main active element of the plant is cannabinol, which has a weak psychotropic effect. The so-called “cure for stress” is recognized today as the most common drug. Marijuana is smoked almost everywhere.

In some countries, cannabis is freely eaten or smoked, in others, storing, distributing and growing a plant is punishable by law.

Many people who had to use this herb are interested in the question of how much marijuana is kept in the urine. This is important because sometimes it is necessary to pass a special test for the detection of narcotic substances in the body.

Diagnostics to identify traces of cannabis are carried out during certain medical examinations (to obtain permission to drive a car, to enter the service, during routine preventive examinations).

That is why you need to know how much marijuana is kept in the blood and urine, what is the period of its disintegration and for how long the substance is removed from the body.

Ways to identify the drug in the body

In medicine, there are several ways to detect traces of cannabis in the human body. The analysis involves research:

  • saliva – the simplest and most common test that allows you to identify traces of the drug, even 3 weeks old;
  • blood is another popular type of testing that is used when necessary to get results in a short time;
  • hair – an analysis characterized by a high threshold of reliability, with the help of which physicians can detect traces of a drug a year or more after its last use;
  • urine – such laboratory analysis helped to detect traces of marijuana a month ago.

How much does the drug held in the body?

Light narcotic properties of hemp give tetrahydrocannabinol (THC). After 30 minutes in the urine of a person who smoked marijuana, there are metabolites of THC, resulting from the process of disintegration of a narcotic substance in the body.

The rate of cannabis removal by the body is due to the following factors:

  • human physiological characteristics (lifestyle, weight, metabolism, age, general health);
  • the duration of the drug;
  • amount of THC consumed.

It follows that each case is purely individual. The breakdown products of tetrahydrocannabinol have a peculiarity lingering in the fat cells of the body.

This is the reason that even after six months with a slight weight loss, some of the metabolites enter the blood and urine.

So how long does marijuana stay in the urine and the blood? Traces of cannabis are eliminated from the body in 10-12 days with a single use.

With rare use, the period of removal of the drug from the body lasts longer – 18 days. If marijuana and hemp are used constantly, their traces are preserved both in blood and in urine from 40 to 120 days.

How to speed up the process of removing marijuana from the body?

There are several ways to quickly remove drug residues from your own body. They help to quickly get rid of harmful substances and prepare for the test.

  1. The use of liquid in large quantities and drugs with diuretic properties. This allows you to remove marijuana residues from the intestines and tissues of the body.
  2. Physical activity. Effective functioning of the lymphatic system affects the cleansing of the body. And the movement of the lymph through the body is provided by muscle spasms. That is, the more a person moves, the faster the intercellular fluid flows in his body, and the faster toxins are eliminated through the lymph nodes and skin. These two points are subject to the same goal.
  3. Dieting. As mentioned earlier, THC metabolites can persist in fat cells, so for the time of detoxification from the diet should be excluded fatty and fried foods, sugar, flour products, pastry and pasta, coffee.
  4. The fastest and most reliable method of cleansing – the use of drugs for detoxification. The most effective at the moment is a FAZETOX detoxifier. The tool is designed specifically for the removal of residual drugs. But before you clear the body of marijuana, you must stop using it.

So, now it is known how long marijuana is kept in the human body, and how to make sure that soon there will not be a trace of it. But the best way is to completely avoid using even light and legal drugs (marijuana, cigarettes, alcohol).

And in conclusion, I would like to remind you what is harmful about marijuana, simply by listing the consequences of its prolonged use.

Energy exhaustion of the body (lethargy, apathy, socialization, hypochondria, psychosis, sleep disorders, schizoid manifestations, narrowing of interests, state of affect, emotional emptiness, hallucinations, paranoia, pseudoparalysis, hysteria).

  • Disruption of the brain and nervous system.
  • Reduced fertility in men.
  • Unhealthy offspring in women.
  • Respiratory diseases (bronchitis, tracheitis, and pneumonia).
  • Immunity dysfunction.
  • The deterioration of the general condition (muscle weakness, fatigue, loss of strength).

And this is not a complete list of dangerous consequences.

We are not talking about the once smoked jamb – anything happens in life. Beware of the need for frequent or constant use of the drug, since the effect of marijuana on the body is irreversible.

The action of marijuana, characterized by euphoria, gaiety, loss of sense of time, attention to detail, ridiculousness, heightened perception of objects of art, lasts 2-4 hours. So is it worth paying so much for these short-lasting pleasant sensations?

Factors that affect elimination rate

How long does the grass stay in the blood?

The exact figure is very difficult to calculate; several factors influence it at once. This indicator may vary depending on the individual characteristics of each person.

Tetrahydrocannabinol (THC) gradually accumulates in the body in fat deposits, as it is a fat-soluble substance.

When calculating the required indicator of time, pay attention to the physiological state of the individual. It is necessary to take into account the anthropometric data, age, gender and rate of metabolic processes.

The percentage of subcutaneous fat is also a crucial factor since it is inside the fatty tissue that hemp keeps. Marijuana traces will erode more slowly if the person has been taking the drug for a long time.

The content of THC in a specific dose of a substance (strength) is another indicator that determines the rate of excretion. The test will show a positive result in cases where the individual used cannabis daily.

How to check the presence of a drug in the body

Many employers are required to conduct a procedure for checking the presence of hashish in the body of employees.

How much grass weeds?

Cannabis will be detected if you have consumed even a small amount of grass on the day of the test.

Urinalysis is a very common and accessible method for determining the result. The doctor will receive the exact answer if a couple of hours have passed since the moment of smoking.

If you take grass daily for several months, a qualitative analysis will show the presence of THC even after a large amount of time after the complete failure. For other grass lovers, the substance is eliminated from the body in 7-10 days.

It is also realistic to determine the presence of marijuana in the human circulatory system. With the help of conventional biochemical analysis, doctors accurately find marijuana in the body.

How long does the substance stay in the blood?

This indicator is highly dependent on the frequency and duration of intake of drugs.

With a single use of the test will be relevant for three or four days. Experienced smokers will be able to remove all traces from the blood only three months after the extreme tightening.

There were cases when the grass weathered much faster. Pay attention to the individual characteristics of each person.

Recently, saliva analysis has become more popular, during which a person is obliged to pass a sample in the presence of doctors or company employees.

The probability of substitution is minimal; it is impossible to deceive specialists. The problem is that any traces of herbs are removed from the oral fluid very quickly. The test will be relevant only on the day of hashish.

If a person regularly smoked a lot of marijuana, then such a rapid test will give a positive result even after several days after smoking.

The analysis of hair follicles is an excellent alternative that can indicate the presence of prohibited substances in the body even 6 months after the use of this drug.

Is it possible to remove the grass faster

Marijuana keeps in the body a lot of time. A person can remove the harmful substance much faster. To do this, try to increase the rate of metabolism. Thus, the grass will leave the body much faster.

Drink plenty of water and take diuretics. After eating hashish, a person is recommended to sweat in a bath or sauna.

Effective helpers in the removal of plant residues from the body are sports and physical labor. The best of all is heavy traffic, during which a person burns many kilocalories.

Do not forget about the mode of proper nutrition. You must ensure normal acid-base balance. To do this, eliminate from your diet, flour, sweet and any dairy products.

There are various medical preparations for detoxification, but their use is possible only under the supervision of doctors.

An experienced specialist can prescribe the necessary and safe dose of the drug by which hemp can get out of the body faster.

How does marijuana affect the body

Although the herb is a weak drug, it can greatly affect a person’s health. The main feature of this substance is that it causes a bright energy depletion.

After how much will this happen?

A person feels more lethargy and apathy on the day after smoking. In some cases, the addict has signs of asocial behavior.

The regular presence of herbs in the body is the basis for mental disorders and sleep problems. Sometimes there are hallucinations and paranoiac reactions.

Blood supply to important brain cells suffers greatly. This is a decisive factor for the formation of some dangerous pathologies.

Thought processes slow down, the level of intellectual abilities of the addict worsens. In men, there is the likelihood of problems with reproductive function. Hashish becomes the cause of the issues with fertilization in the body.

Women are obliged to give up such a bad habit during pregnancy. Thus, it is realistic to avoid the development of various pathologies in the fetus.

How many days does the grass go?

Only a long time after the complete abandonment of hash, you can have a child.

Marijuana strongly affects the organs of the human body. Many have big problems with the upper respiratory tract. Smokers often suffer from bronchitis or pneumonia. Immunity also suffers, the protective abilities of the body deteriorate. Appears lethargy and weakness, power indicators fall several times.


Hemp is a common type of soft drug that is widespread in our country. This illegal substance affects the health of any person.

How long does the grass last?

It all depends on the individual characteristics of the organism. Many employers conduct regular tests for the presence of THC elements in the human body.

There are several types of testing. Men and women often donate blood, urine, saliva or hair. Such a test can show a positive result even after a couple of weeks after the extreme tightening.

How does the drug

The main active compound of marijuana is tetrahydrocannabinol (or THC). This is a vegetable psychoactive substance located in the leaves and inflorescences of the plant. HNS, entering the body, forms strong compounds with fat cells (adipocytoma).

Diagnostics that detect traces of the anashi are performed during certain medical examinations (upon entering the service, obtaining permission to drive a car, during routine preventive examinations).

Tetrahydrocannabinol has a psychotropic effect on the central nervous system of a person who uses a drug. Take marijuana simultaneously with food or as a smoking mixture. Despite the moderately severe severity of HPS, the herb leaves the body for quite a long time.

HPS accumulation process

After ingestion/smoking of ananas, certain biochemical processes occur in the human body, provoking the formation of metabolites. Molecules of these compounds are characterized by a long period of disintegration and withdrawal. It is the metabolites that are detected during the tests.

The time, how much marijuana keeps in the body individually, it depends on the characteristics of the human body, on its innate level of metabolism. For some individuals, the test result can give a positive result, even if the weed was smoked last time several years ago.

What determines the decay rate of metabolites

Cannabinol is a fat-soluble compound. The rate at which a drug leaves the body depends on the following factors:

  1. The duration of the use of anasha.
  2. The peculiarity of the metabolism of this person. It affects weight, height, and age.
  3. The strength and saturation of the drug itself, the “purity” of the herb and the percentage of cannabinol in it.
  4. The level of body fat in the body. The larger it is, the longer the narcotic traces remain.

With prolonged and regular use of marijuana in different forms, its concentration increases. In the analysis will be revealed anasha in the urine, blood, saliva and even hair.

How much marijuana is kept in blood and urine

Testing can identify the effects of taking the drug already after 1-1.5 hours after its use. The time for which traces of weed remain in the body depends on the duration of taking the narcotic substance.

Traces of marijuana in the blood

To determine how much grass is kept in the blood, you need to remember how often it was used:

  • with a single use of anasha, the drug remains in the blood cells for 3-5 days;
  • with the systematic smoking of cannabis, its traces remain in human blood for 3-4 months.

The presence of anasha in the urine

But the question of how much marijuana is kept in the urine is not so happy with the answer. An herbal drug in urine is delayed for a more extended period:

  • if weed was smoked only once, the traces of the drug would be determined by analysis about 1-1.5 weeks;
  • when a person regularly smokes marijuana, the breakdown of metabolites is longer and is 4-6 months, in some cases, anasha will persist for up to a year.

How is the analysis performed?

Doctors have developed several ways to determine traces of anasha in the human body. In the analysis can be investigated:

  1. Saliva. The most common and simple test. Allows you to detect traces of the drug more than 3 weeks ago.
  2. Blood. It is also one of the most popular tests. It is used when you need to get results in a short time.
  3. Hair. The analysis has a high threshold of reliability. With it, doctors track traces of the drug, even a year or more after its last use.
  4. Urine. This laboratory analysis revealed traces of an anachas a month ago.

Is it possible to speed up the withdrawal process

How much cannabinoids are kept in the urine depends on many components. But is it possible to accelerate the breakdown of toxins and cleansing the body?

If you soon have to analyze for traces of anasha, you should prepare for testing beforehand and try to do everything so that there are no traces of a dangerous substance in the body.

To speed up the cleansing of the body and safely pass the analysis, you should start preparing for it in advance. What we do:

Adjust the power. Marijuana has an adverse effect on acid-base balance. To correct the alkaline level, it is necessary to saturate your own body with fresh vegetables thoroughly. For the time being, flour, meat, and dairy products are excluded from the menu.

There is a common opinion that if you drink a lot of water, it will “dilute” the anasha and bring it out. This is a myth, the liquid only dilutes urine, but does not affect the concentration of cannabinol.

For 5-6 days before testing it is recommended to take vitamin complexes or dietary supplements (nutritional supplements) with an increased amount of creatinine. On day X (when testing is being carried out), take 90–100 g of B vitamins and drink a large amount of water (at least 2 liters).

Actively involved in sports and visit the sauna. In the coming days, before the analysis will have to become vigorous athletes. Physical activity well increases the metabolic process (metabolism) and accelerates detoxification. Promote cleansing and bath procedures.

Detoxification therapy. If testing indicators are of great importance, as an extreme case, medical methods can be applied to completely cleanse the body. This method is considered the most effective and reliable, but it can be done only in a hospital.

Useful tips

If urine is analyzed, try to hand over the first trickles by the collection cup. This will lower the level of metabolites (concentrated substances leave the body the very first).

But when putting your hair on the traces of the drug, you have to resort to extreme measures and completely shave your hair.

A haircut is best done as soon as you know that you have to pass the tests. Before the analysis starts, the hair will grow and the probability that they will be “clean” will increase.

But the most effective advice is not to take any drugs at all, even light anisha . Most smokers believe that marijuana does not have particularly negative consequences for the body. This is a big mistake, according to the observations of narcologists, smoking marijuana, even once, can cause a person:

  • death of brain cells;
  • dramatically lower immunity;
  • the development of mental illness;
  • a manifestation of schizoid disorders;
  • full energy depletion of the body;
  • to provoke the appearance of sexual impotence in men;
  • the prolonged state of weakening, lethargy, and apathy.

Marijuana is a crafty and dangerous drug. Its long-term use is persistent addictive. When the weed already ceases to act, smokers, accustomed to euphoria, switch to stronger drugs and completely degrade. Anasha – a direct path to the destruction of the individual. Take care of yourself!

To begin with, it should be noted that even if a person no longer smokes marijuana, it remains in his body. And this is not so much marijuana itself, but its active substance THC (tetrahydrocannabinol).

Tests for narcotic substances seek THC in saliva, hair, urine and sometimes in the blood. In the case of saliva, marijuana leaves the body quickly, and it takes more time to detect it than other drugs. With home dough, cannabis can be detected approximately one hour after ingestion. Leave marijuana saliva will be within 12 hours. After that, the accuracy of the home test results will significantly decrease.

When it comes to urine testing, the time during which THC can be detected depends greatly on the amount and frequency of cannabis use. It may remain in your urine for up to 45 days, but usually, it is something between a week and a month.

Lovers of smoking marijuana on a frequent or even daily basis can expect a positive urine test for at least 3 weeks since their last contact with marijuana.

And even people who have tried marijuana only once should not be too reckoned on the negative – it will be positive if the test is passed in the time interval between a couple of days and a week with a little. Most often, marijuana can be detected in the urine after 2-5 hours after the first use.

And even if marijuana / THC has left your saliva and urine, they can remain in your hair follicles. When you use a drug, it gets into your blood. The blood feeds your hair and helps it grow, and if there are traces of drugs in the blood, they end up in the hair.

After about a week after the last use of the drug, the hair will grow enough to be trimmed, and then the presence of narcotic substances can be determined by your hair. Drugs take a long time to leave the hair.

Commercially available tests can detect them no later than 90 days from the moment they are ingested, but such tests that are capable of more can be assigned in court.

Body hair also contains traces of narcotic substances, and since hair grows more slowly on the body, the “window” for determining drugs is 1 year. However, the accuracy of the determination of marijuana in the body through the hair leaves much to be desired.

Therefore, even those who regularly smoke marijuana can expect a negative result (just as those who smoke it rarely, can hope for a positive).
However, this state of affairs is not at all typical of other drugs, which are often determined precisely by the hair, for example, cocaine. Marijuana can also be identified through the hair, but this method is not as reliable as the urine test, which is 98% accurate.

One of the main factors affecting the duration of the presence of marijuana in your body is the frequency of use. THC is soluble in fat, so when smoking marijuana, THC is absorbed into fat cells. After a few days, THC enters the bloodstream, and your body is cleansed.4

However, if you smoke marijuana regularly, the amount of THC in fat cells will exceed its maximum for being in the blood, so THC (and, accordingly, evidence of marijuana use) will remain in your body for much longer.

The effect of marijuana use on the body

A feature of taking this type of drug is pronounced energy depletion. Typical lethargy, apathy, hypochondria. Signs of asocial behavior appear. Manifestations of mental disorders, sleep, schizoid symptoms develop.

A person becomes emotionally devastated, hallucinations, hysterical and paranoiac reactions are possible. Together, the symptoms are called “amotivational syndrome.”

The blood supply to the brain cells is impaired, this leads to the pathology of trophism and cell death.

The activity of thinking processes gradually decreases, the intellectual abilities of a person decrease significantly. Also, a possible effect is sterility – men due to the effects of narcotic substances lose their ability to fertilize.

When women use the drug, serious pathologies of the fetus are possible, the risk of miscarriage and fetal death is high.

The effects of marijuana on the respiratory system is very destructive. The consequences are considered to be inflammatory diseases of the upper respiratory tract: bronchitis, tracheitis, pneumonia.

The general somatic state of a person is deteriorating – this is manifested by muscular weakness, loss of strength, fatigue. The systematic use of marijuana reduces the body’s adaptive response, leading to a weakening of the immune properties.

Diagnostic tests for cannabinol detection

Analysis of urine. When conducting determined by the presence of cannabinol metabolites in the urine. More complex test systems can estimate the exact concentration of substances.

Saliva analysis. A quick test that can accurately detect the fact of taking a drug.

Blood test. It is carried out if it is necessary to receive urgent results. The information content of the test is high with the recent use of marijuana.

Analysis of hair follicles. High-precision test will determine the fact of drug use up to six months ago.

Methods for removing metabolic products of cannabinol

Contrary to popular belief, it is impossible to remove the drug from the body with increased water intake. The fluid dilutes urine, but it does not affect the rate of elimination of cannabinol.

Partially speeding up the excretion can help physical education, as well as bathing procedures. They can speed up the metabolism, which allows a faster rate to clear the body of the decay products of the drug.

Also, it is better to eat properly to restore the body’s acid-base balance. To do this, add spinach, cucumbers, celery, cabbage to the diet and exclude oxidation stimulants, which include milk, sausages, and flour products.
