  1. Default How long does it take for Xanax to leave your system (drug test)

    Took xanax over weekend and my school has random drug testing twice a week. How long will it take for this to clear my system?

  3. OMG what school do you go to? Is it public?

  4. it takes 48 hours or so to get out of my system

  5. I have been told anything that is water soluble aka if drop it in a cup of water and it dissolves is out of you system in 24-48hrs. Your best beat if you’re really worried about it is to drink a lot of water and exercise. This will flush out your system faster than anything naturally.

    Xanax has a half life of 11.2 hours, 16.3 hours (elderly), and 19.7 hours (for those with alcoholic liver disease).

    So after your last dose your system should be clean about 23 hours. However, it could be longer if someone is abusing xanax and taking very high doses or if their health is compromised and they cannot process the xanax as fast as other healthy individuals.

    My advice would be to drink plenty of water after the last dose to help flush your system. You could also try using a product designed to flush your system that contains goldenseal and other herbs after the last dose to flush your system. You can find these products at head shops. Some are better than others, do your research.

  7. if your not taking them on a regular basis then..48hrs they should be outa your system.

    Xanax goes out of your system rather quickly. I would say anywhere from 24-72 hours. I would give it four days just to be safe.

    I actually had a drug test about 9 hours after doing 8mg of xanax. I drank a QCarbo32 (I think that is the name of the drink) two hours before the test and passed. If you need more info on that, I'd be happy to help.

  9. I was taking random drug tests for a while and passed one even though I had taken Xanax the night before. I also drink a lot of water and I think a lot of it just has to do with your body.

    remember that could just be 1. the type of test was not testing for benzos and or 2. they administer the drug tests only to a select few of the total population of samples. schools have a budget. they're not going to spend it all on drug testing.. i wouldn't be surprised if they just threw away the samples and used the testing as a scare tactic. anyways.. drinking water and cranberry juice should help it pass your system faster..

    This test is administered to me every month from my personal physician. I literally pee in a cup and then watch them drop the urine into each of the 5 or 6 things they test for. The drug test looks almost exactly like the one in the picture below. I have to sit in the room right behind the nurse and wait for her to circle positive or negative for each one and then hand the sheet back to my doctor before he will write me a prescription. Sometimes he has a 10 panel test, and sometimes a 5 or 6 panel test, but every time Benzos have been on the list. They are not supposed to be taken with the drug I am prescribed (Suboxone), so he always tests for that.

    I have never been a believer in drinks, but I have also never been in this much of a "danger zone" right before a drug test. I googled something real quick and came across that drink. You are supposed to drink the entire 32oz bottle 2 hours before you test, and then 64 oz of water on top of that. It tells you to urinate a few times before you go in. My urine was literally a neon yellow/green color when I provided the sample

    Anyway, I'm not sure if I passed because of the drink, because I drank a bunch of water, or that their test has a higher minimum threshold for benzos, but it was indeed a legitimate test.

    However, you bring up a good point about drug tests being expensive and being used as more or less a scare tactic for kids. I'm sure that is being used more than people think. My doctor actually charges me $60 just for the the drug test itself.

  12. Wow.. your school does random drug testing? what if you were to refuse? That is kinds intrusive. What meds your on is none of their business. IMO

  13. If it's something really important I would give it a whole week to clear out of your system. It really depends on how fast your metabolism is!

    This is not for school. I'm on Suboxone treatment and my doctor gives me a drug test every month before writing my prescription

  15. It will take about 4 half-lives to get a drug out of your system. xanax is around 12 hours so figure 2 days. but it depends on how much you take, how good your liver is at clearing and how sensitive the test is.

    it also matters what time of day you take test and how much water you drink and void out first

    alprazolam can actually show up in your system two weeks after discontinuing use depended on alot of factors I.E. habitual user, ocasional user, etc but, the national drug testing cut off for urine analisis is legally a 4 day cut off. in other words although capable, they can legally only go back 4 days so most all DT are designed accordingly.

  17. Default days

    The half-life (time it takes for 50% of the drug to be removed from the body) is 10-12 hours. Since storage in the fat cells is negligible, theoretically it would take only a few days to clear xanax. However, if you are taking other benzodiazepines or very large amounts of xanax, I'd recommend being clean for a week. What the drug text actually tests is for Benzodiazepines, not Xanax specifically, so make sure there is no valium, restoril, ativan etc in your system either.

    My mothers pain management doctor has had to switch drug testing companies 3 times since January, according to the doc, due to alot of false positive test results. At any rate, we were told that the anti depressant medication Zoloft will very often show up on a urine drug screen as xanax.

  19. what about ativan? Does that take longer to clear than Xanax?
