Hemp (Latin Cannabis) is a genus of annual bast-fiber plants of the Cannabaceae family. Previously, as the classification changed, hemp was classified as mulberry, mulberry and nettle. Includes one polymorphic species - Cannabis sativa L. (Hemp sowing), previously divided into several types:

  • Cannabis indica Lam. - Indian hemp, sometimes classified as Cannabis sativa subsp. indica
  • Cannabis sativa subsp. sativa
  • Cannabis ruderalis Janisch. - Hemp weed

Marijuana (Spanish marijuana, marihuana), the official name cannabis is a psychoactive drug derived from hemp. The effect on the human body is associated with psychoactive substances (cannabinoids) contained in hemp, the most effective of which is delta-9-tetrahydrocannabinol. Specialists distinguish three main types of hemp: Cannabis sativa, Cannabis indica and Cannabis ruderalis, while the latter contains the least amount of tetrahydrocannabinol.

Transliteration from its Latin name cannabis is often used to refer to psychoactive substances derived from hemp. In English, “cannabis” (cannabis) is traditionally called psychotropic cannabis used in medicine, and “hemp” (English hemp) is the corresponding crop. The 1961 UN Single Convention on Narcotic Drugs includes hemp in the list of drug-containing plants and obliges the governments of the participating countries to strictly control its cultivation.

Cannabis smoking - inhalation of cannabis smoke (hemp) to obtain a specific intoxicating effect due to exposure to the body of psychoactive substances contained in hemp - cannabinoids (the main of which is THC, tetrahydrocannabinol). Smoking is the most common way to use cannabis. Cannabis smoking is considered a traditional attribute of various youth subcultures and is used in some ceremonial and ritual activities. It is also used for medical purposes. Cannabis is banned in many countries.

How much marijuana is retained in the body depends on the consumer, as well as the frequency of use. There are other factors that influence, for example, how the test is conducted.

THC lasts the longest in the hair follicle; in saliva it can be detected for the shortest period of time. Other factors include metabolic rate.

Typically, this is how long marijuana stays in the body:

Duration of detection of THC in urine (when smoking)

Once 5-8 days
2-4 times a month 11-18 days
2-4 times a week 23-35 days
5-6 times a month 33-48 days
everyday 49-63 days

Tab. one

The most common THC test is urine analysis, because it is the cheapest and has a long detection period. However, the detection period will depend on the frequency of consumption due to the cumulative effect of THC (the effect of the accumulation of concentration in the body).

  • Having smoked once , the test for THC will be positive up to 8 days.
  • With frequent smoking, the test will show the presence of THC for 15 days.
  • THC can linger up to 30 days in the urine of a tightly smoking consumer.
  • The test will be positive up to 45-90 days if you smoke several times a day daily

Dates of detection of THC in saliva

Least of all THC is retained in saliva. This method is most often used by the traffic police if there is a suspicion that the driver is stoned. The test will be positive one hour after use, as well as within 12 hours.

Timing of detection of THC in the hair

Как долго марихуана выводится из организма?

In the hair follicles, THC is retained for the longest period of time. The test will be positive within 7 days in the case of a single use, most of these tests can detect THC within 90 days in the case of systematic use. However, this method is not reliable, therefore it is almost never applied.

The timing of the detection of THC in the blood

THC is almost never measured in the blood, because its metabolite in it does not stay for a long time. As a result, a blood test for the presence of cannabis in it shows only recent use.

How to get a urine test for THC

Как долго марихуана выводится из организма?

Unfortunately, there is no reliable way to take the urine test if you are a heavy smoker. There are drugs that help cleanse urine, but their reliability is in question.

The most effective approach to taking a urine test for THC is to drink plenty of cranberry juice or plenty of fluids. Consuming large amounts of water will naturally dilute everything in your urine.

The most reliable way to pass the test is to adhere to the recommendations on time (tab. 1)

How long are other chemicals removed from the body?

In continuation of the topic, it will be interesting to pay attention to how long other chemical compounds are retained in the body:

  • Heroin can be detected in blood and saliva up to 12 hours after use, and in urine up to three days.
  • Amphetamines can be detected within 12 hours in blood and saliva, in urine 1-2 days after use.
  • Alcohol (one standard dose - 0.5 l. Low alcohol / 200 g. Wine / 50 g. Strong) can be detected in the body within 5 hours (the more consumed, the longer it is absorbed and excreted from the body).

Recently, many employers are testing their employees for drugs. However, if you have problems with amphetamine, getting out of the water is easier than using marijuana regularly. Cannabis is in the body longer than almost all other chemical compounds, due to the cumulative effect. However, everyone knows that you will not necessarily be stoned for 12 hours after consumption. Smokers who fear a fairly common urine test should take a job that does not require this test.

MYTH

The active component of marijuana - tetrahydrocannabinol (THC) - is captured in the body by adipose tissue. And since THC is released from fat cells slowly, its psychoactive effect can last days and weeks after taking the drug. Long-term preservation of THC in the body damages internal organs containing a large amount of fat, especially the brain. "THC molecules are very mobile, they penetrate through the lipid membrane of the cell membrane into its nucleus, disrupting the chemical process of cell division." "Cannabinoids accumulate in fat cells, and a brain weighing three pounds per third consists of fat ... Therefore, millions of ... axons are constantly surrounded by THC in the brain of a chronic marijuana smoker." "Cannabinoids, which are soluble only in fats., Accumulate in the tissues of the body ... Anyone who uses marijuana more than once a week ... cannot be drug free." "Even people who use marijuana just once a month continuously expose their brain, lungs, liver, and other vital organs to the toxic effects of THC."

FACT

Many active drugs and drugs penetrate the body's fat cells. The difference, but not unique property of THC is that it leaves fat cells slowly. As a result, traces of marijuana can be detected in the body days and weeks after ingestion. But within a few hours after smoking marijuana, the content of THC in the brain drops below the concentration necessary for a noticeable psychoactive effect. Fat cells in which THC is retained are not damaged in the presence of the drug, just like the brain and other organs. The most important consequence of the slow elimination of marijuana is that it can be detected in the blood, urine and tissues long after consumption and much later than the end of the psychoactive effects of marijuana.

THC, like many other psychotropic substances, is processed in the body. After THC enters the bloodstream, most often from the lungs during smoking, a small part (about 1% of the dose taken) enters the brain, where it binds to specific receptors. If the amount of the drug in the brain exceeds the threshold dose, its psychoactive effect is manifested. The maximum action is usually observed after 15-30 minutes. after the start of smoking.

At the same time as THC enters the brain, it is distributed to all other parts of the body. In the process, the concentration of THC in the blood drops, which reduces the amount of drug available for binding to brain receptors. In 2–4 hours, the level of THC in the brain usually falls below the level necessary for psychoactive action. As shown in Fig. 16-1, if the concentration of THC is reduced to 2-25 ng / ml, psychoactive effects are usually soaked.

Many drugs, including THC, are fat soluble. This allows them to easily penetrate into cells throughout the body, dissolving in cell membranes, which are mainly composed of lipids (fats). Drugs leave most of the cells quite quickly - either in their original form or after biotransformation in the cell - in the form of water-soluble metabolites. After re-entry into the bloodstream, drugs can undergo further biotransformation, especially during passage through the liver. As a result, the entire drug and its metabolites are excreted from the body with sweat, excrement and urine.

THC enters most cells in the body and leaves them at about the same rate as other psychoactive substances. Nevertheless, some features of THC, and above all its high solubility in fats, slow its release from fat cells. THC does not specifically select fatty tissue. Like many other drugs, such as Valium, Pentothal, and Thorazine, THC is slowly released from fat cells. Since biotransformation occurs weakly or does not occur at all in fat cells, a certain amount of active THC again enters the bloodstream. However, THC released from fat cells is too small to have a psychoactive effect. In fact, none of the effects of marijuana lasts more than a few hours. A number of researchers have reported mild effects of marijuana lasting up to 24 hours. At the same time, in dozens of other studies when evaluating psychomotor activity and intellectual activity, it was found that all the effects of marijuana disappear within a few hours after smoking.

Even in frequent marijuana users, the level of THC in the blood drops below the psychoactive level a few hours after a single smoking. Figure 16-2 shows the concentration of the drug in the blood with repeated smoking for 36 hours. A certain amount of THC from previous use is mixed in the blood with THC from a new dose. However, the amount of drug released from fat cells is too small to produce a significant effect. As a result, those who smoke rarely and those who smoke often, the psychoactive effects of marijuana lasts only a few hours. If people smoke marijuana more often than shown in Fig. 16-2 (for example, every hour), the level of THC in the blood and brain will be higher, but even in this case, those small amounts of previously taken THC that are constantly released into the bloodstream from fat cells will not significantly affect the level of intoxication.

After smoking marijuana, THC remains in the adipose tissue for a long time, but there are no THC receptors in the fat cells, and this is probably why the presence of the drug in adipose tissue does not lead to any consequences. The brain is not at all an organ especially rich in fat, despite frequent claims to this effect, and THC does not accumulate in it. Small amounts of THC also accumulate in some other organs, but there is no evidence that it changes the functions of cells or causes structural damage to them.

Ultimately, THC is biotransformed into inactive metabolites, but since it slowly leaves adipose tissue, moving to places of its biotransformation, days and weeks can pass before the drug and its metabolites are completely eliminated. As a result, drug testing at the workplace and other types of testing can detect marijuana users for a long time after using the drug and much later than the end of its psychoactive effect.

Any drug is a powerful poison that destroys the entire body. Damage caused by drug use is irreversible. Drugs primarily affect the nervous system and brain.

As a result of exposure to narcotic substances, the intellectual abilities of a person are reduced, and he gradually becomes stupid, reaching idiocy. Changes in the brain under the influence of a drug can be compared with schizophrenia. Therefore, it will be absolutely fair to agree with the statement that drug addiction is voluntary madness.

The character of a person is changing. He becomes lethargic, lethargic and withdrawn. He is not interested in anything. Friends can not stand being in his company for a long time and in the end turn away from him. The human brain and psyche change irreversibly. They do not fully recover even with timely drug withdrawal.
