One of the most accessible and effective ways to check the presence of narcotic substances in the body is to analyze urine for drugs. This study will help in the shortest possible time to determine whether a person has taken prohibited drugs in the next few days (from 3 to 7).

The effectiveness of the study is that narcotic substances initially enter the blood, and are excreted with the kidneys or liver. Since narcotics have a low molecular weight, their metabolic products fall into urine. They completely emerge from the body only after 2-3 weeks.

Technique of the urine analysis for drugs

The technique of carrying out in the first place depends on the goals. To check a loved one or a relative, it's enough to take an express test. If there is a need for medical analysis, there are two main ways to examine urine:

  1. Chemical and toxicological analysis. It is considered the most accurate. It helps to identify the presence of all narcotic drugs, as well as psychotropic drugs. The duration of the study is 1-7 days. It depends on the type of examination. If necessary, you can challenge the chemical-toxic urine test for drugs. If a person does not agree with the results, he can reapply urine;
  2. Immunochromatographic (express test). This is the most accessible method. The result will be ready after 10-15 minutes. A study is carried out immediately after the collection of the material. Strips with special impregnation are used for this. They can be purchased at any pharmacy. The essence of the test is as follows: if the body received narcotic substances, the color of the strips varies. This method allows you to find in Urine about 14 of the most common prohibited substances. Express urine analysis for drugs does not show the severity of drug intoxication.

Since some medicines also refer to the narcotic, it is necessary to warn about the use of medicines before conducting the research of the laboratory assistant. It is better to make a list of drugs.

What can the laboratory analysis show?

Many are interested in what the urine test shows for drugs. First of all, it helps to determine the presence of toxic compounds in the body. The time span is influenced by the body weight of a person, a variety of drugs and their chemical properties.

It should be noted that narcotics are derived from the human body in different ways. Some of them can persist for 30 days. Even if the body received a small dose of narcotics, the analysis will be able to identify it.

How long do drugs persist in the body:

  • marijuana. In inexperienced drug addicts, the substance is excreted through the adipose tissue for 3-4 days. With prolonged use, marijuana can be detected after 30 days;
  • cocaine can be detected eight days after the last intake;
  • ectasia. It does not matter, in tablets or capsules the drug has got into the body, after three days from the moment of its use it can be revealed in urine;
  • heroin (7-8 days).

The laboratory analysis determines which of the drugs a person has taken and sets the approximate time for regular admission. Only after getting acquainted with the results of the tests, the doctor can talk about the diagnosis of "drug addiction". Also, external signs of drug addiction are taken into account and revealed: pupil status, lack / tremor of upper limbs, speech.

If the analysis gave normal indicators and confirmed that there are no narcotic substances in urine, the narcologist issues a certificate.

Before going through the study, you need to find out how much the urine test for drugs is. The reference from the narcologist for employment is valid for 12 months. And results of analyzes are valid only one month.

Is it possible to deceive the analysis for drugs?

People who periodically or systematically take banned drugs, are interested in how to get around the urine test for drugs. According to the law, a person has the right to disagree with the research, but the consequences may not be the most pleasant. In some situations, it is necessary and representatives of the authorities are able to conduct the procedure forcibly.

There are several ways to get around the analysis:

  1. Long. If the exact date of the procedure is known, you can take care of and clean urine in advance. To do this, increase the amount of fluid intake to 3 liters. Positive impact is having a sport, especially jogging. To get a negative result, you need to forget about drugs and alcohol;
  2. Fast. If there is not enough time, you can try to drink plenty of water and do not go to the toilet until the material is collected. Some add urine to citric acid.

However, no one can guarantee that these methods will help to deceive the analysis. It is difficult to say whether to deceive the research when it comes to drugs. It is worth pondering and trying to direct all its forces to combat drug addiction. This will help to avoid dire consequences.
