The duration of the delay of narcotic substances in human biological materials
Alcohol (from Arabic. الكحل, al-kuħl - “antimony” through Latin. Alcohol, in medieval Latin, this word means powders, distilled water) - in Russian, most often acts as a synonym for phrases ethyl alcohol (ethanol) and alcoholic beverages ( that is, beverages containing ethyl alcohol in significant concentrations).
Drug (from the Greek. Ναρκωτικός - resulting in stupor, Greek. Νάρκωσις - stupor) - according to the definition of WHO - a chemical agent that causes stupor, coma or insensitivity to pain. The term usually refers to opiates or opioids, which are called narcotic analgesics.
When you need a reliable confirmation, a person uses drugs or alcohol, a crucial way to check tests. There are not many methods that can give a true assessment of the results. And there are not so many laboratories in which it is possible to use these methods.
Acting Minister of Health of Ukraine Uliana Suprun said that narcotic substances or alcohol are stored in human biological materials with different duration, which depends on how often a person accepts them, she wrote on her page on Facebook.
Paradoxically, no matter how destructive narcotic substances are for our body, they are not as easy to detect as they seem at first glance.
That is why athletes or persons who have committed a crime undergo thorough examinations and take biological fluids in special laboratories.
For thorough analysis, specific equipment is needed, acting on a completely different method. This should be a long process of research (2-3 days) based on analytical chemistry. Namely: gas chromatography-mass spectrometry.
Everything else, such as test strips that promise a result in 15 minutes, is not a reliable indicator.
There are not so many laboratories in Ukraine that can do such research. Even less - to ensure that it will be carried out qualitatively.
The most modern equipment for this is only in the anti-doping center of the Olympic Committee. It is they who work with athletes to determine if they use prohibited substances.
This equipment analyzes the following biological materials: urine, hair, nails and even blood, where drugs are very rapidly metabolized. If a person regularly (1-2 times a week uses drugs), this method will confirm this.
The presence of alcohol in the body is easier to confirm than drugs. To do this, use the chromatographic method. However, it is faster excreted from the body.
In sports competitions, the practice of collecting samples of analyzes under the supervision of experts. Such measures are carried out in order to avoid falsification or replacement of analyzes.

In the urine
- Alcohol 10-12 hours
- Amphetamine, Methamphetamine: for 2-5 days
- Cannabis 1 to 30 days
- Barbiturates: up to 7 days
- Cocaine: 1 to 3 days
- Opiates like codeine, morphine and heroin from 2 to 5 days
- Alcohol 24 hours
- Amphetamines 10-14 hours
- Methamphetamine: 24 hours
- Barbiturates: 1-2 days
- Cannabis: 6-24 hours
- Cocaine: 12-24 hours
- Codeine: 6-12 hours
- LSD: 0-3 hours
In the hair, traces of narcotic substances appear after one week from the time of use. But they remain there for a very long time - up to 90 days and even more. Hair grows at a rate of about 1 cm per month, so depending on its length, you can determine drug use in recent months.
In the nails
In the nails, traces of narcotic substances can remain for a long time - from 3 to 5 months in the nails on the hands and from 8 to 14 months in the nails on the feet.

A drug is a chemical agent that causes stupor, coma or insensitivity to pain. The term usually refers to opiates or opioids, which are called narcotic analgesics.
The 1961 United Nations Convention on Narcotic Drugs defines the term “drug” by literally listing the substances:
Narcotic drug - any of the substances included in the lists I and II - natural and synthetic.
According to the US Code, the term “narcotic drug” refers only to opium, cocaine, their derivatives and analogues, as well as opiates in general, but many other substances belong to the first List of Schedule I drugs, criteria for which there are three conditions, two of which are subjective, and the third (B) follows from them:
(A) The drug has a high potential for abuse.
(B) The drug does not have accepted medical use in medical practice in the United States.
(C) The permissible level of risk when using the drug under medical supervision exceeds medical norms.
The official recognition of a substance as narcotic is its inclusion in the list of drugs by order of the Minister of Health in Ukraine.
Drug [narcotic] Chemical agent that causes stupor, coma or insensitivity to pain. The term usually refers to opiates or opioids, which are called narcotic analgesics. In the conventional medical and legal sense, it is often used inaccurately to refer to illicit narcotic drugs, regardless of their pharmacology.
It is believed that the term "ναρκωτικ" (drug) was first used by the Greek healer Hippocrates, in particular, to describe substances that cause a loss of sensitivity or paralysis. This term was also used by the eminent ancient physician Claudius Galen. As such substances, Galen, for example, mentioned mandrake root, eklate seeds and poppy seeds.
At the end of the 20th century, the meaning of the term in Russian expanded. The difference from the initial value is related to the assignment to drugs of substances not previously designated by this word (such as cannabis products, psilocybin mushrooms, etc.).
In English, the word "narcotic" is still referred to only as opioids. It should not be confused with the word “drug”, the most accurate translation of which is “drug”.
Currently, the term “drug” is sometimes used in Russian medicine and jurisprudence not quite accurately, in the extended sense, denoting by it all prohibited psychoactive substances regardless of their pharmacology, as well as in translations of English-language medical and legal documents, in which illegal drugs are called drugs, not narcotic drugs.
Currently, drug trafficking is limited in most countries. As of November 1, 2009, the number of parties to the 1961 Convention or this Convention, as amended by it in accordance with the 1972 Protocol, reached 186, which is 96% of all states. Of these, 184 States were parties to the 1961 Convention, as amended by the 1972 Protocol. Afghanistan and Chad are parties only to the 1961 Convention without amendment. Eight states did not join the 1961 Convention: Equatorial Guinea, Timor-Leste, Vanuatu, Kiribati, Nauru, Cook Islands, Samoa and Tuvalu.
