Drug screening or regularly scheduled drug testing requires knowledge of substance detection durations based on drug classes and test system types. The duration of different drugs’ effects varies greatly, as well as their residual traces in the body. The high from LSD, for example, lasts 6 to 12 hours (and the detection period for urine testing is 2-4 days), whereas the high from cocaine lasts about 30 minutes (and the detection period is similarly a 3-day period), subsequent detection periods range based on a series of factors related to the type of drug consumed and the subject of the test.
The same would go for how long a drug remains in the body’s systems after its effect has worn off. Some drugs remain detectable for months, while others disappear in hours. The duration of time a drug remains in your system is determined by the type, amount, and frequency of administration. Here, we’ll discuss how long different drugs stay in your body and what factors influence that duration.
Factors That Affect the Duration Of Drugs In Your System:
The time it takes for the body to clear a drug from the system is determined by several factors besides the type of drug. These factors include the following:
- Half-Life:
The half-life of a drug, also known as the elimination half-life, represents how long it takes for a drug’s concentration in the body to reduce by half. The balance between metabolism and excretion rates determines the half-life of any drug. In the case of substance abuse, the half-life of a drug determines how long its effects will remain in the body.
- Weight and Metabolism:
The duration of time drugs stay in your system might be affected by your weight. Drugs will stay in your system for longer if you have a higher body fat percentage.
- Tolerance:
If you have developed a tolerance to the drug by repeated use, it will metabolize more quickly in your body. It results in a shorter duration of stay in your system.
- Amount Consumed and Frequency Of Use:
The amount of the drug you use affects how long it stays in your system. A drug may only be in your system for a short time after a single-use. However, repeated usage, either all at once or over a long time, might result in increased concentrations of the drug in your body, resulting in the drug staying in your body for much longer.
- Alcohol Consumption:
It is harmful to mix alcohol and drugs. If you drink alcohol while taking drugs, the drug may stay in your system for longer
Duration Of Stay of Different Drugs in Your Body:
The durations mentioned here are estimates of how long drugs will usually last in your system. Remember that these durations may fluctuate depending on various factors for different people and their particular circumstances.
Marijuana:
First-time marijuana users are more likely to pass a drug test than people who smoke marijuana many times per week. The detection time depends on the drug test:

- Hair Test: Up To 90 Days
Ecstasy:
MDMA, sometimes known as Ecstasy, is an illegal synthetic drug used to induce sensations of well-being, pleasure, and altered perception. It can have many adverse effects, some of which may be fatal, and the amount of time it stays in the body is dependent on several factors. Ecstasy is detectable on:
- Blood Test: Up To 2 Days
- Urine Test: Up To 4 Days
- Saliva Test: Up To 2 Days
- Hair Test: Up To 90 Days
Meth:
Methamphetamine, often known as meth, crystal, ice, or Tina, is a highly addictive synthetic stimulant of the central nervous system. It is detectable on:
- Blood Test: Up To 3 Days
- Urine Test: Up To 1 Week
- Saliva Test: Up To 4 Days
- Hair Test: Up To 90 Days
Vyvanse:
Lisdexamfetamine, also known as Vyvanse, is a stimulant medicine. This drug is detectable on:
- Blood Test: Up To 8 Hours
- Urine Test: Up To 4 Days
- Saliva Test: Up To 2 Days
- Hair Test: Up To 90 Days
Morphine:
Morphine belongs to the class of drugs known as narcotic analgesics (pain medicines). It reduces pain by acting on the CNS. This drug is detectable on:
- Blood Test: Up To 3 Days

- Blood Test: Up To 6 Hours
- Urine Test: Up To 3 Days
- Saliva Test: Up To 1 Hour
- Hair Test: Up To 90 Days
Fentanyl:
Fentanyl is a synthetic analgesic drug that is 50 to 100 times more powerful than morphine. This drug is detectable on:
- Blood Test: Up To 2 Days
- Urine Test: Up To 3 Days
- Hair Test: Up To 90 Days

- Blood Test: Up To 24 Hours
- Urine Test: Up To 4 Days
- Saliva Test: Up To 2 Days
- Hair Test: Up To 90 Days
Alcohol:
The liver is primarily responsible for the breakdown of alcohol, which can metabolize around one standard drink an hour. Alcohol detection times can vary depending on the body system and test performed.
- Breath Test: 12-24 Hours
- Blood Test: Up to 6 Hours
- Urine Test: 12-72 Hours
- Saliva Test: 12-24 Hours
