The answer to the question, how long do drugs stay in your system? depends on the way and the type of drug that you used. The duration also depends on how much, how often, or how long you usually take drugs. The metabolism of drugs varies from person to person. It also relates to the body’s composition, genetic and biological contributors, sex, and age.

Typically, drugs take a few days or even a few hours to leave the body and remain undetected in a drug test. According to NSDUH (National Survey on Drug Use and Health), one out of ten adults used drugs a month before 2016. You may feel the effect of the drug for a few minutes or hours, but the substance is active and present in your body for a longer time.

How Your Body Metabolizes Drugs

It is impossible to determine how long drugs stay in your system and are detectable in saliva, blood, or urine tests. Many factors determine how your body metabolizes drugs, or you remain under the effects of drugs. Here are some factors that impact how long drugs stay in your system and how it reacts with your body:

Drug Tolerance

If you have a higher tolerance for drugs, it metabolizes more quickly. This will decrease the length of time that the drug remains in your body.

Body Mass and Hydration

Your physical activities, body mass, and hydration levels play an active role in affecting how long do drugs stay in your system and is detectable. If you have more fatty tissue in your body, drug traces may remain detectable for a longer time. This happens because drugs build up in those tissues and stay in your body for a longer time.

Acidity of Urine

The acid-base balance in your urine also impacts the length of time that drugs stay in your system. If your urine is more acidic, it will lower the detection time.

Amount or Frequency of Use

Another essential factor that has a vital impact on detection time is the frequency and quantity of drugs used. If you are taking the drug for the first time, it may be detectable for a short period of time. If you are a heavy or long-time user, the detection time is longer. This means frequently using drugs can increase the duration that drugs remain in your system.

The Duration That Drugs Remain in Your System

Contrary to what drug testing companies advertise, not every drug leaves its chemical signature in your body for the same amount of time. When we take the drug, regardless of whether we swallow, smoke, or snort it, the substance begins to break down.

After you feel the drug’s effects, the substance reacts within your body, producing metabolites and byproducts. These byproducts linger in your urine, blood, and even hair. Drug testers look for these metabolites, as these are good indicators that you are on drugs, or might have accidentally come in contact with the drug.

Tests that involve detection through hair are fairly accurate, unlike a urine, blood, or saliva test. These tests are unable to detect major drugs for more than a week sometimes. For instance, heroin is undetectable after three to five days with a urine test.
