Why does it matter ? It would not fair you on a drug test that I am aware of ? ( assuming this is an issue)
Very short day or two at the most, but I can't see it being there an issue

Xanax, a Benzodiazepine, will stay in your urine anywhere from 1 - 42 days. It is currently unknown how long they stay in saliva, blood, and hair.

Well, I may be able to help you with this. I took a single dose of Xanax (0.50 MG) 3 weeks ago then about 2 weeks later I took another single dose of Xanax (0.50 MG) 178 hours ago (7 days, 10 hours) and purchased a 12 panel home drug test kit at wal-mart for $35 (First Check Home Drug Tests - the most advanced home drug and health tests. Home Drug Test Information. - Inverness Medical (http://www.firstcheckfamily.com) for more information) then piss tested myself (178 hours have passed since my last dose of xanax & 168 hours have passed since my last dose of Oxycodone (15 MG) ) and passed the test (without dilution)

Cut off levels are 100 ng/l for Oxycodone & 300 ng/l for Benzos.

I was told since xanax has only a 12 hr. halflife(the shortest of any benzo) its passed in urine way faster than other benzos which I know for sure can stay in urine for up to 30 days I was told xanaxx should not be detected after 3 days but other benzos way longer. Is this true

Yes unless you've been taking for years.

I just called the addictions # & he said 2-5 days for a urinalisis. BUT, I would drink plenty of water . Also you might want to take this bottled stuff called "THE STUFF".( If it's that important)

Oh you can get "THE STUFF" @ any health food store :)

If I been taking xanax bars 2mg everyday for weeks and taking 3 or more a day how many days would it get out my system? I just want to know cause I have a piss test soon.

How long does xanax bars 2 mg get out your system if you been taking it everyday for a year or more?

The duration of your Xanax use will definitely weigh on how long the drug can be detected in your urine. If you have been taking a moderate to high dosage for a year, you will need at least 5 to 7 days for the drug to be undetected in your urine. However, you DO NOT want to stop Xanax cold turkey unless your life depends upon it. People withdrawing from Xanax and similar drugs have been known to experience fatal seizures and other horribly dangerous symptoms. I realize the importance of passing a urine screen. I take one monthly and my life depends upon it. However, please PLEASE be extra careful. Good luck to you and I hope you fare well.

If you are being urine screened for a job, you may not even be tested for Xanax. However, probation or clinical settings will call for a full panel screening. Since you have been using the drug for a year or more and it is a moderate dosage, you will need to give yourself 5-7 days for the drug to be undetectable in the urine. However, you do not want to withdraw from Xanax cold turkey without medical attention close by. You could suffer from fatal seizures or other horrible withdrawal symptoms. Please be careful and good luck.

I have 2 answers from 2 different doctors that have suboxone programs, for which benzos are a big NoNo!!
The 1st doctor said 72 hours, and the 2nd doctor said 7 days. I am a LPN and was taught in Pharmacology that it was 30 days. So where the truth lies I don't know but if anyone can figure it out let me know so I can actually pass a drug screen with my own urine.

all I know is I get random drug screenings at a methadone clinic going on 3 yrs now and I take either ativan or xanex which both have relatively low half lives { xanex's is a little longer than ativan's} but I only take 1 to 2 days off at the most before going in on my pick up days and I'v passed every time... I do have a very fast metabolism though. I would stay away from klonopin though, it has an unusually long half life among the benzodiazipam family which most people would'nt assume, since it is on the weaker side as far as benzos go. If you need to find out accurate half lives [ which is basically half the amount of time a drug metabolizes in... so in other words say the half life is 12 hrs... multiply that by 2... check out wikapedia for reliable info. But always waiting as long as u can, drinking pleanty of water and taking your meatabolizim into concideration is important. There is really no difinative answer for this question because every one's different and there are a lot of factors that effect how fast your body expels a drugs even down to simple things like your diet, if you take vitamins or supplements etc. So I'm just sharing my personal expierance with how I'v managed to pass my drug tests. I hope this was helpful to someone.

It also helps to find out how many panels are on the drug screen. The more panels the more expensive the test. Most pre-employment tests are only 5 panel coke, meth, metham. pot, opiates. The 12 panel and higher will have benzos and opiods. Most people (including myself or a LONG time) don't realize that Opiates are like morphine, opium, heroin, codeine... Vics and Roxys are opiods, hydrocodone and oxycodone are synthetic opiates (opiods) and don't show up on a 5 panel.
I've taken a single .25 xanax in the afternoon and had a saliva test the next morning without it showing up. This has happened several times with has shocked me, I was fully expecting to fail.

I took 3mg of xanax this weekend and I have a drug test on Friday, that was the 1st time I've took xanax in well over a year what are the chances that ill fail?

Xanax does stay in urine any where from 3-5 days however like klonapin staays in urine from 7-21 day wide range huh? Well good luck I take valume and xanax daily there for it takes me like 14days to be clear of benzos clonzapam is my fav. But I'm on subutex so can't take benzos lol but there's ways around it get yer urine from trustworthy source and get a wizz kit they work wonders exspensive yes... But way worth yer freedom

I have to take a piss test every 2 weeks at my Pain Clinic and I took 10 1mg Xanax 5 each day for 2 days and had to take my piss test 4 days later and I passed ;) and they even send my test to be further tested by doing a special test that the look at it through a micro scoop and everything came back okay :) so I think that if you only take it every once in a wile then you should be fine within 3 to 4 days!So sense I know by first hand experiences,I think I should get some respect and not made fun of unless you make fun of me in a funny clever way ;)

I have read lots and lots of posts on how long xanax stay in your system. I could not get a good answer so I did a test on myself to see. I went to walmart and bought a 12 panel drug test. I ate 1 mg of xanax. 5 days later I took the test and not only was there not a faint line the line was thick as if I have never taken the drug. It tested for 300/ng and was 100 percent pass. Hope this helps
