The following chart gives approximate detection periods for each substance by test type. Data for urinalysis are reproduced from LabCorp’s.

The detection windows depend upon multiple factors: drug class, amount and frequency of use, metabolic rate, body mass, age, overall health, and urine pH. For ease of use, the detection times of metabolites have been incorporated into each parent drug.

For example, heroin and cocaine can only be detected for a few hours after use, but their metabolites can be detected for several days in urine.

The graph depicts the longer detection times of the metabolites.

Drug Detection Periods

Substance Urine Hair Blood
Alcohol 3-5 days via Ethyl Gluconoride (EtG) metabolite or 10-12 hours via traditional method 12 hours
Amphetamines (except meth) 1 to 2 days up to 90 days 12 hours
Barbiturates (except phenobarbital) 2 to 3 days up to 90 days 1 to 2 days
Benzodiazepines Therapeutic use: 3 days. Chronic use (over one year): 4 to 6 weeks up to 90 days 6 to 48 hours
  • Single Use: 2 to 7 days
  • Prolonged Use: 1 to 2 years
up to 90 days 2 days
Cocaine 2 to 4 days up to 90 days 24 hours
Codeine 2 days up to 90 days 12 hours
Cotinine 2 to 4 days up to 90 days 2 to 4 days
Heroin 2 days up to 90 days 6 hours
LSD 2 to 24 hours Up to 3 days 0 to 3 hours

* Oral fluid or saliva testing results for the most part mimic that of blood. The only exception is THC. Oral fluid will likely detect THC from ingestion up to a maximum period of 18–24 hours.

* Urine can not detect current drug use. It takes approximately 6–8 hrs. post-consumption for drug to be metabolized and excreted in urine. Similarly, hair requires two weeks, and sweat, seven days.

Drug Detection Time

The results of federally mandating drug testing were similar to the effects of simply extending to the trucking industry the right to perform drug tests, and it has been argued that the latter approach would have been as effective at lower cost.

  1. I took half of a tylenol 3 Saturday at 10 am then I pissed for a test on Thursday. What are the odds of me failing this? I had never taken it and my girlfriend gave it to me for a headache.

  2. First of all–you’re dates on how long drugs stay in your system are incorrect. It can take up to 4-5 days for methamphetamines to get out of your system EVEN if you are not a heavy user. If you do a 1.5grams in one day, you could still be positive in 4-5 days. I know this because it happened to me

    Also- if you are a heavy user of opiates, you might as well increase your day by one.

    Really it depends on the state of your metabolism though. If you are a fat lazy sonofabitch you will most likely not metabolize teh drugs through your kidneys/liver as easily as someone who is younger and active and weighs less.

    Dont listen to the asinine advice that websites like this give you. Better yet–don’t do drugs for a week before any test, or just don’t do them period. If you are on probation (which I am, and have been for a long time) just dont do them at all. You will eventually get caught, and jail and prison is no fun. Go back to school, get a job, or get a hobby.

    If you want realiable information on such topics only got to .gov; .edu websites or look up actual medical journals. Websites like this land people in jail or without jobs.

  3. Also–if someone like your kid tells you that they are testing positive because a drug like an opiate is still in their system from months ago DONT LISTEN TO THEM THEY ARE LYING. There is no way an opiate would stay in your system for more than 5 days TOPS. It’s not marijuana, and it’s half-life is not long enough to keep it in your system that long. Dont be stupid if someone tells you such nonsense. They are lying.

  4. Hi everybody, to pass any drug test you need a detox drink. Iv been on probation for 7 years and am a chronic xanex and heroin user. iv never failed a test. my secret is alot of water and vale x4 strength detox drink. Search for it online or your nearest head/pipe shop. they should have it. you must drink a shiv load of water prior, dont take any illegal/un prescribed drug 12 hours prior and dont eat anything at least 8 hours before the test. after a full gullet and several pisses, consume the entire drink and fast! then fifteen min later fill the bottle w/ water and slam that in your belly. dont drink anything after that. you must time test perfectly to take three pisses prior to the test in a two hour time frame. so 4th piss at the two hour mark is prime for the test. use the middle of your stream cause begginin and end are dirtiest parts. if you abide these simple instructions youwill not fail.

  5. Bezoes-xanex, klonopin, valium etc
    stay in system up to two weeks
    cocaine- stay in system up to 5 days
    amphetamines- meth, aderral, ritalin, bath salts etc
    stay in system 3-7 days
    thc/marijuana-stays in system 2-4 weeks
    opiates-opana,dilloted, heroine, oxycodone/oxycontin/percocet, vicodoin, morphine etc
    stays in system 3-6 days
    barbituates-sleeping pills
    stays in system 5-12 days
    alchohol- necture of the gods
    stays in system 24-32 hours
    lsd/ACID!!! and psilocybin-mushies
    stays in system 6-24 hours but cant show on urine analysis plus really expensive blood or hair test(unlikrly to be tested)
    DMT- window to the gods
    leaves system within six hours but also naturly produced so technically never leaves and cant be tested
    PCP- stays in system 3-6 weeks
    All these stats must be taken into consideration of fat content of body, metabolism, age, and usage. ex if you weigh 250 lb., are 42 years old and are smoking an eighth of chronic marijuana on top of a perscription of oxycodone odds are you will be testing hot for the longer end of the spectrum. If you are a seventeen year oild with barely any body fat, have a super fast metabolism, weigh 125 lb and have mostly muscle, odds are that hit of marijuana you just hit for the first time in your life last night will be out of your system in a week and a half.

  6. Ud be surprised how fast opiates can leave ur system..i kno people who snortd 4 30mg roxis n pissd clean the mext day jus from drinkn water.

  8. Question,

    If I take two doses (tabs) of LSD on saturday evening (6 p.m) and have a potential urinalysis monday at 7 a.m. Will I test positive?

    Are there any ways to flush LSD from your urine within that time period that would produce clean urine at test time?

    Please help!


  9. that 3 days for methadone to leave ur system is total bullshit. i used methadone 5 days ago when i was still in prison and i reported to my state parole officer for the first time this go ’round and i failed that shit miserably. i am 5’7 , 172 lbs. and im physically fit with a high metabolism. Yeah,explain that one. i’ve only been out 2 days and i had to pull some Stephen Hawking type shit to talk myself out of going back to prison already. It’s a damn good thing that i have the gift of gab and im a pretty intelligent person cuz i would be in a cell right now thanks to me going by the info on this site. No tolerance, no habit, i just used 20mg ONE TIME and that shit was still lighting that test up to the max after 5 days. My suggestion to anybody in the same situation is to fake that shit and use some clean piss cuz your booked. Or even better, DONT DO IT AT ALL. Just thought i’d post this valuable information cuz i know addiction all too well and we don’t do well on parole/probation. Getting sent back to prison for relapsing is like locking someone up cuz their cancer came out of remission…BE SAFE …ITS NOT WORTH YOUR FREEDOM!!!!

  10. lsd is not on any 6-7- or 8 panel test so u dont even have to worry bout that shit girly……..actually….i’ve never even heard of somebody failing for acid in my life….unless they just invented some test for it very very recently, i am positive that they can’t even get it from ur urine.

  11. this sight is knocked tha fuck off…….this is for michele,,,,always be safe though,,,i just did 31 months in prison so they may have a urine test for lsd now,,,do ur reasearch but tread with caution cuz the bullshit info i got about the methadone on this sight threw my ass under the bus. If ur on any parole or probation the max they use are 8 panel tests and they do not have lsd on them. Suboxone (bupanorphine) isn’t on ther either but they always have a special single dip test for that. That test is 85$ a dip so they only test for it if they have suspicion that u used it so they might hav that for lsd now too…..i wish u luck…always research for advice and if u still dont feel comfortable about it, hav somebody piss for u in a small visine body and keep in in ur little girly part till u get to takin the test,,that way it stays body temp….jus some advice from someone whos been through this shit way too many safe

  12. My question is.. I am female 5’3″ 95-100lbs I’ve been taking percocet about 60mg/day for about a month or so I started taking them for tooth pain but it lead to taking them for the euphoric feeling they gave me I have a urine drug test coming up in 4days and am wondering how long will it take for the percocet to clean our of my system and is there any chance of me passing this test if I dont use from now til I get tested?

  16. Everyone says cocaine stays in your system 72 hours but I took a drug test after smoking coke probably about a quarter ounce and took a urine test 12 days after and it showed up in my urine I and nothing else pretty muscular low body facts about 130 pounds I would never suspect asked if I knew you was gonna come out bad now I believe that it depends on how much how often. So the 72 hour thing I have no faith in I found out the hard way

I can pass a pre test anyway (have done so many times) but I’m worried about the blood test. Anything I can take or do to make it get out faster? I’m a heavy girl about 230 in my 30’s, and I’m pretty active….. Any help is much appreciated.

  30. I took a 5 mg of valium I am like 5 foot nothing and weight about 85 pounds…..what is the best case scenario when it would be out of my system going for a drug test for a job (hopefully) anyways….do they test for benzos? Or just the normal illegal street drugs?

  31. Is there a blood and/or urine test to show how you have taken your meds for the past month! Hydrocodone.

  32. Everyone I I have been prescribed opiates benzos muscle relaxers muscular dystrophy and probsbly 10 medical diagnosis and 5 mental diagnoses since a doctor ( a pretty strict one at that ) put me on 90 hydro 7.5 90 month ans .5mg klonopin 90 month plus seroquel neurontin….I have abused almost every illegal substance except for a few new research chems….I went to pharmacy school at WVU for 3 years but by that time I’d already done my research. For the past 18 years everybody called me dr.Blake or “the walking pharmacy ” cause prescription and illegal I had almost everything at all times……I’ve gave advice and dosed and took care of all my friends my family and my dog….if u wanna know anything 90% sure I’ll know it if not it won’t take me long……to the girl asked how long hydrocodone would stay in and asked if it would be out 13 days from then…don’t worry it all opiate based pain pills except for synthetics like bupenorphine (SUBUTEX OR SUBOXONE) and methadone stay in at the longest 4 days…..if Uve taken them for years it only takes 4-7 complete detox no trace. This also includes heroin coca in methamphetamine and amphetamines. One dose of subutex or methadone I’d say 7 or 8 days….if Uve been taking these regularly for a while it can take 14 to 21 days. Fentanyl is also synthetic but does not show up unless you get the ultimate drug test by a gas chromatography mass spectrometry analysis. …it’s a million dollar machine and u usually only find them in big universities. For a doc or law or job to do that would cost at least couple grand. So very unlikely. ….benzodiazapens single dose 4-7days…used regularly for while 2-4 weeks….muscle relaxers like so mad 2-4 days…..Marijuana occasionally use 1-2 weeks. ….habitual use up to 45 50 days…..lsd cannot be detected except through a spinal tap….ecstasy 2-5 days. …these are for urinalysis. In most cases they stay in ur blood even less. Hair is the bitch everything lasts longest in….if u know u have to give hair sample for job u can get special shampoo and go through a couple step cleansing process. ..Google it people. My parting words….if u have any doubts and if there not parole staring at ur dick…get clean piss put in ur crotch area a little before the test and it will always be right temperature. …if u have use detox products or hair cleansing. ..MAKE SURE U TAKE TIME TO DO THE RESEARCH! !!! 90% WILL LET U DOWN I’VE SEEN IT HUNDREDS OF TIMES. …AND THE OLD CHUG LOTS WATER THING DOESN’T FLY ANYMORE. ..THEY ALWAYS CHECK COLOR AND CAN CHECK AND PROVE UVE BEEN CHUGGING TOO MUCH WATER…IT STILL WORKS GREAT BUT DO RESEARCH TO FIND OUT AMOUNT….B12 ALONG WITH THE WATER B12 IS A VITAMIN THEY CAN’T GET YA FOR THAT. BUT LIKE I SAID I’VE TAKEN COCKY PUSSY PHARMACISTS AND DOCS IN DEBATE AND KNEW EVEN MORE CAUSE I’VE EXPERIENCED IT ALL 20 YEARS. ATTN:!!!#!! MY EMAIL IS if anybody ever has a question or needs help don’t hesitate to email. …I’m disabled and bored most time anyway. I’ll give u the truth and like I said…my niece finished pharmacy school 2 years ago and works at Wal-Mart. ..we like to get together and compete for fun. I taught her a lot over those 6 years a lot that u won’t learn in books. And sometimes she beats me on diabetes heart thyroid etc….like I said opiates benzos antipsychotics muscle relaxers antidepressants sedatives add adhd meds (amphetamines salts)… every illegal substance there is…..those are my expertise. I can also tell u how used properly medically what’s good for certain conditions. …dosages and mixing…side effects. ..the whole line. NO SHIT I JUST WANT TO HELP AND IT’S MY PASSION. ..EMAIL ME AND POST IT ON HERE…DOESN’T MATTER WHICH FIRST. BUT MY ANSWER WILL BE TIMELY AND U CAN TRUST IT….I’VE ALSO BEEN A CHEMIST FOR 14 YEARS SO…HMU ANYTIME PEOPLE

  33. Teri Lynn. ….usually 99% time it will be simple urine or blood to make sure ur taking ur medicine….just get some in ya 3 to 4 hours before test….as far as testing levels it takes highest level multiple million dollar machines usually only big universities have….it’s called gas chromatography mass spectrometry. …it’s the machine invited where u can take anything from Earth and it will break down exactly what %of everything that’s makes it up…down to the atomic level. It would cost doctors insurance company thousands of dollars so it’s hardly ever approved. …it’s only used for vehicular manslaughter cases sometimes high government jobs….or if catching u slipping will put u away for long time cause Uve became a huge problem to law enforcement (like if u deal big amounts they been after u years)…so don’t worry just make sure u have some in ur system
