How Long Do Drugs Stay In The Body?

In: Drug Testing

5 Oct 2007

Drug Detection Times refer to the “window” of detection for drugs of abuse. If a person is tested too soon or too long after use, drugs may not show up in human urine. Often someone will ask us, How long to drugs stay in the body? This short guide will help to answer that question. For the purposes of clarity, this guide is a reference for the detection of drugs of abuse found in human urine.

How long do drugs stay in your system? The length of time that the presence of drugs of abuse in the body can be detected is an important factor in drug screening. The chart below outlines approximate duration times. When interpreting the duration for the presence of drugs of abuse in the body, you must take into consideration variables including the body’s metabolism, the subjects physical condition, overall body fluid balance, state of hydration and frequency of usage.

Urine Drug Test

Drug Detection Times in urine are expressed below in terms of lower and upper boundaries. The amount of time that a drug/metabolite remains detectable in urine can vary, depending on the following factors:

  • Amount and Frequency of Use: Single, isolated, small doses are generally detectable at the lower boundary. Chronic and long-term use typically result in detection periods near or at the upper boundary.
  • Age: In general, human metabolism slows with age, resulting in longer drug detection periods.
  • Body Mass: In general, human metabolism slows with increased body mass, resulting in longer drug detection periods. In addition, THC (the active ingredient in marijuana) and PCP are known to accumulate in fatty lipid tissue. Chronic users, physically inactive users, and individuals with a high percentage of body fat in relation to total body mass are prone to longer drug detection periods for THC and PCP.
  • Metabolic Rate: Individuals with slower body metabolism are prone to longer drug detection periods.
  • Drug Tolerance: Users typically metabolize a drug faster once a tolerance to the drug is established.
  • Overall Health: In general, human metabolism slows during periods of deteriorating health, resulting in longer drug detection periods.
  • Urine pH: Urine pH can impact drug detection periods. Typically, highly acidic urine results in shorter drug detection periods.
  • Note: In a small percentage of cases, users may test positive longer than times shown – most notably in cases of long-term chronic abuse, in individuals with significant body mass and/or body fat, and in individuals with health related issues resulting in abnormally slow body metabolism…

Drug Detection Times in Urine

  • Alcohol 24 hours or less
  • Amphetamines 1 to 4 days
  • Barbiturates Short-acting: 1 to 3 days

Long-acting: 1 to 3 weeks

  • Benzodiazepines Short-term Therapeutic Use: 1 to 3 days

Long-term / Chronic Use: 1 to 3 weeks

  • Cocaine 1 to 5 days
  • LSD 1 to 2 days
  • Marijuana (THC) Casual Use: 1 to 7 days

Long-Term / Chronic Use: 1 to 4 weeks Note: THC, the primary active ingredient in marijuana, is stored by the body in fatty lipid tissue. From there, it is slowly released into the bloodstream for up to several weeks – depending on the amount and frequency of use and the user’s level of physical activity.

Drug Testing Lab

In chronic and physically inactive users, THC may accumulate in fatty tissues faster than it can be eliminated. This accumulation leads to longer detection periods for these individuals. Also, users with a high percentage of body fat in relation to total body mass are prone to longer drug detection periods for THC.

  • MDMA (Ecstasy) 1 to 4 days
  • Methadone 1 to 4 days
  • Methamphetamines 1 to 4 days
  • Opiates 1 to 5 days
  • PCP (Phencyclidine) Casual Use: 1 to 7 days

Long-Term / Chronic Use: 1 to 4 weeks Note: PCP is stored by the body in fatty lipid tissue. From there, it is slowly released into the bloodstream for up to several weeks – depending on the amount and frequency of use and the user’s level of physical activity. In chronic and physically inactive users, PCP may accumulate in fatty tissues faster than it can be eliminated. This accumulation leads to longer detection periods for these individuals. Also, users with a high percentage of body fat in relation to total body mass are prone to longer drug detection periods for PCP.

Does marijuana drugs show up in the blood test or urine test? The result came up after 3-4 days and the urine was very little.

Hi:
Can you suggest a book or web-site that has the following information?

You say the amount and frequency of use: single, isolated, small doses are generally detectable at the lower boundary. Chronic and long-term use typically result in detection periods near or at the upper boundary.

What are the boundries (quants) for:
1. Alcohol
2. Amphetamines
3. Methamphetamine
4. Barbiturates
5. Phenobarbital
6. Benzodiazepines
7. Cannabis
8. Cocaine
9. Codeine
10. Cotinine
11. Heroin
12. LSD
13. Morphine
14. Methadone
15. PCP

I appreciate your supplying this information to me, and any scale of boundry, like “quants: 1 to 100″ that will give me some idea of tolerance and chronic usage; for example, if a person has a quant of 64 for cannabis on a urine test, does this tend to support mild use or heavy use, long term use . . . ?

Thankyou,
Charles Rivenbark

This has been the most helpful site so far, but my question is for a heavy user of hydrocodone for 4 to 5 years eating minimum of 15 pill daily, how long would that stay detectable in her system for a over the counter drug test? She says she last slipped in May of 2008 but she failed my drug test this Saturday July the 5th. My daughter says it was from the long term usage. How do I find out the truth?

Thanks

Hi Franco,

>question is for a heavy user of hydrocodone

Tested for in Standard Drug Tests? NO
Tested for in Extended Drug Tests? SOMETIMES
Detection Period in Urine 3-4 days

Hydrocodone may not cause a positive result in a standard opiate urine test. Many opiate tests test only for morphine (which both codeine and heroin break down into). This is true for both home/business kits and laboratory testing. Hydrocodone does not break down into morphine, and is therefore not detected by these tests.

But home and laboratory testing is available that will detect hydrocodone (and hydromorphone, which it breaks down into). So test results will depend on the particular type of test that is used and whether or not laboratory verification is required. If a home drug test is given and the opiate test shows a positive result (due to hydromorphone use), a laboratory verification might NOT result in a positive test because the lab may only test for morphine. In this case, the lab would NOT be able to verify the original positive result.

The only way to be sure if you will test clean is to test your self before you go to the employers test. This can be done easy with an instant drug test.

1+ pack of smokes per day for 5 years. 14 days after quitting-cold turkey with 1 cigarette smoked on day 2 = negative cotinine test for me. From all I have read, 4 days after quitting smoking should equal a negative cotinine test; however, a genetic flaw in some people could fudge the results and make a positive test for a longer period of time. I do know someone who smoked the same as me and tested negative after 4 days smoke free and lots of water. Hope this helps someone.

i recently drank 22 red bulls in under a two hour sitting.Shortly after consumption, i felt extremely sick. My friend told me this drink contained bull sperm and that the reason i was sick was because i was developing “wings”. I thought this sounded stupid, but he insisted that the wings can only be detected in urine.Is this true, and if so, will the drug test reveal my wings and keep me from getting a hand job?

Hello.
I have been using 2mg hydromorphone (IV) pretty much on a daily basis(give or take a week or two in which I do not have the drug)for a little over one year. I have been off of the drug for about 16 days straight. Will I test positive for opiates if I were to take a drug test today?
