How long does it take for a urine test to detect drug use

People who are under heavy pressure often choose some methods to relieve their stress, so some people will choose many wrong methods to relieve their stress. For example, some people release themselves by taking drugs, but this can be addictive and can cause great harm to the body. It can also cause people to become thin. Next, let's find out how long it will take for urine tests to detect drug use.

1. Negative urine test after taking drugs for several days

Generally, drugs will show positive results in urine test 6-8 hours after entering the body, and most people will naturally metabolize them after 5-10 days, which means that urine test will show negative results after 5-10 days. Of course, if you have poor physical fitness, it may take 12-15 days to complete the metabolism, while if you are in good health, the test results may turn negative after 3-4 days.

2. Factors affecting urine test time

1. The main factors affecting the length of time are: metabolic function, water intake, exercise volume, temperature, work and rest schedule, drug use history, and drug use frequency. Take methamphetamine and heroin as examples. Most of them cannot be detected in about 7 days. These 7 days are just an average. The fastest person could not be detected in less than 4 days, and the slowest could take up to 20 days.

2. This is affected by various factors, such as local weather, environment, physical factors, etc. If the weather is hot where you are, your metabolism will be faster. For example, if a person has a long history of drug abuse, with short intervals between drug abuses and a large amount of drugs taken each time, then it will take a long time to eliminate the toxins. Of course, we still recommend that family members should conduct regular testing. On the one hand, they can know the drug addict's testing time range as soon as possible, and on the other hand, they will not be able to detect the drug addict by taking advantage of the time loopholes.

Many drug addicts, without the financial resources to purchase or use drugs, die from various complications caused by severe physical withdrawal reactions, or commit suicide due to unbearable pain. Withdrawal reactions are also an important reason why drug addicts find it difficult to quit.

3. Mental disorders and abnormalities: The most prominent mental disorders caused by drug abuse are hallucinations and thought disorders. Their behavioral characteristics revolve around drugs, and they may even lose their humanity because of drug abuse.
