Hemp (lat. Cannabis) is a genus of annual bast-fiber plants of the Cannabaceae family (Cannabaceae). Previously, as the classification changed, hemp was attributed to silk, mulberry and nettle. It includes one polymorphic species - Cannabis sativa L. (Hemp seed), 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 (sp. Marijuana, marihuana), the official name of cannabis is a psychoactive drug derived from cannabis. The effects on the human body are related to the psychoactive substances (cannabinoids) contained in hemp, the most effective of which is delta-9-tetrahydrocannabinol. Experts identify three main types of cannabis: Cannabis sativa, Cannabis indica and Cannabis ruderalis, while the latter contains the least amount of tetrahydrocannabinol.

For the designation of psychoactive substances derived from cannabis, transliteration is often used from its Latin name - cannabis . In English, “cannabis” (English cannabis) is traditionally called psychotropic cannabis, used in medicine, and “hemp” (English hemp) is the corresponding crop. The 1961 United Nations Convention on Narcotic Drugs includes cannabis in the list of narcotic plants and obliges the governments of the member states to strictly control its cultivation.

Smoking cannabis is the inhalation of cannabis smoke (cannabis) to obtain a specific intoxicating effect due to exposure to the organism of cannabinoids contained in cannabis (the main one is THC, tetrahydrocannabinol). Smoking is the most common way to use cannabis drugs. Smoking cannabis is considered a traditional attribute of various youth subcultures, it is used in some ritual and ritual activities. It is also used for medical purposes. Cannabis use is prohibited 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 performed.

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

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

The timing 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 test for THC is the analysis of the urine, 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 (accumulated concentration in the body).

  • Having smoked once , the test for THC will be positive for 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 smoked consumer.
  • The test will be positive up to 45-90 days , if you smoke daily several times a day.

The timing of detection of THC in saliva

Least of all THC is delayed 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, and also for 12 hours.

The timing of detection of THC in the hair

Как долго марихуана выводится из организма?

In the hair follicles THC is delayed for the longest period of time. The test will be positive for 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, so it is almost never used.

The timing of detection of THC in the blood

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

How to pass a urine test for THC

Как долго марихуана выводится из организма?

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

The most effective approach to passing the urine test for THC is to drink a lot of cranberry juice or a lot of liquid. Consuming large amounts of water will naturally dilute everything that is in your urine.

The most reliable way to pass the test is to adhere to the recommendations for time (Table 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 linger in the body:

  • Heroin can be detected in blood and saliva up to 12 hours after consumption, and in urine up to three days.
  • Amphetamines can be detected within 12 hours in blood and saliva, in urine 1-2 days after consumption.
  • 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 it is consumed, the longer it is absorbed and removed from the body).

Recently, many employers are testing their employees for drugs. However, if you have problems with amphetamine, it is easier to get it dry than with regular use of marijuana. Cannabis is found in the body longer than almost all other chemical compounds, due to its cumulative effect. However, we all know that you will not necessarily be high for 12 hours after consumption. Smokers who fear a fairly common urine test should get a job that does not require passing this test.

MYTH

The active component of marijuana - tetrahydrocannabinol (THC) - is captured in the body by adipose tissue. And since THC is slowly released from fat cells, its psychoactive effects can last for days and weeks after taking the drug. Prolonged preservation of THC in the body damages the internal organs that contain large amounts 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 to fat cells, and the brain weighing three pounds by one third consists of fat ... Therefore, in the brain of a chronic marijuana smoker, millions ... of axons are constantly surrounded by THC." "Cannabinoids, which dissolve 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 only once a month continuously expose their brain, lungs, liver and other vital organs to the toxic effect of THC."

FACT

Many active drugs and medicinal substances penetrate the fat cells of the body. The difference, but not a unique property of THC, is that it leaves the fat cells slowly. As a result, traces of marijuana can be found in the body days and weeks after admission. But after a few hours after smoking marijuana, the content of THC in the brain falls below the concentration required for a noticeable psychoactive effect. The fat cells in which THC is retained are not damaged in the presence of the drug, as well as 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 use and much later than the end of the psychoactive effects of marijuana.

THC, like many other psychotropic substances, is recycled in the body. After THC enters the bloodstream, most often from the lungs during smoking, a small part of it (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 action is manifested. Maximum action is usually noted in 15–30 minutes. after the start of smoking.

Simultaneously with the entry into the brain, THC is distributed to all other parts of the body. In the process, the concentration of THC in the blood decreases, which reduces the amount of drug available to bind to brain receptors. In 2–4 hours, the level of THC in the brain usually falls below the level required for psychoactive action. As shown in Fig. 16-1, if the concentration of THC is reduced to 2-25 ng / ml, psychoactive effects usually become overwhelming.

Many drugs, including THC, are fat soluble. This allows them to easily penetrate cells throughout the body, dissolving in cell membranes, which are mainly composed of lipids (fats). Drugs quickly leave most cells, either in their original form or after biotransformation in the cell, in the form of water-soluble metabolites. After repeated entry into the bloodstream, drugs may 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, feces and urine.

THC enters the majority of body cells 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 adipose tissue. Like many other medicinal substances, for example, Valium, Pentothal and Thorazine, THC is slowly released from fat cells. Since biotransformation in the fat cells is weak or does not occur at all, a certain amount of active THC re-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 last more than a few hours. A number of researchers reported weak effects of marijuana that persist for up to 24 hours. At the same time, in dozens of other studies, in assessing psychomotor activity and intellectual activity, it was found that all the effects of marijuana disappear within a few hours after smoking.

Even in frequent users of marijuana, blood THC levels fall 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 the previous use is mixed in the blood with THC from the new intake. However, the amount of drug released from the fat cells is too small to produce a significant effect. As a result, those who smoke rarely and those who smoke often have only a few hours of psychoactive effects of marijuana. 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 in this case, those small amounts of previously accepted THC, which 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 it seems that therefore the presence of the drug in the adipose tissue does not lead to any consequences. The brain is not at all an organ of particularly rich fat, despite frequent statements to this effect, and THC does not accumulate in it. Small amounts of THC accumulate in some other organs, but there is no evidence that it changes the function of cells or causes structural damage to them.

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

Any drug is the strongest poison that destroys the entire body. Damage caused by taking drugs is irreversible. Drugs affect primarily the nervous system and the 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 the drug can be compared with schizophrenia. Therefore, it would be completely fair to agree with the statement that drug addiction is voluntary madness.

Changing the nature of man. He becomes lethargic, apathetic and reticent. He is not interested in anything. Friends can not stand in his society for a long time and in the end they turn away from him. The brain and psyche of a person change irreversibly. They are not fully recovered, even with a timely withdrawal from the drug.
