Drink plenty of water. I mean plenty. Drink so much that you urine has "0" color. No color indicates no specific gravity or a very low level. Worst case senerio is that your test would be considered " diluted ", but not altered. Meaning the person drinks has consumed to much water to have an acurate test conclusion for that time.
Get someone else's urine and put it in a small plastic container that is spill proof. Get 2 hand warmers, the one's you shake and they warm up, and rubber band it on each side. Then slide the bottle into your ground area while wearing baggy pants or long underwear, securing it so it doesn't move....
If it's a urine test, drink a ton of water, anything else fake it or your screwed.
Drink a lot of water until your urine is clear. If you want put about 1-3 squirts of visine in your urine. Works for me every time. In fact I'm about to have to do that.

Yes. the envelope for a saliva test is 12-24 hours
No you can not pass a drug test by drinking vinegar. You can however make a salad.
No. That is a myth.
its painkiller and it can be tested after 50 hours
Nope, it stays in you for 48 hours.
The drug Xanax does not stay in the saliva for more than 12 hours. If taking a saliva drug test the drug would not be detectable after 12-24 hours.
if your asking if you take half a xanax, and have a drug test the same day, will you pass? Then my friend the answer is no. Xanax half life is 6-12 hours. If you took it extremely early in the morning, and it was half of a 0.25 mg pill, you might have a 2% chance of passing.
There are no magic potions that let you pass a drug test if you have used within the time limits of the test. You're either going to have to stop doing drugs or stop trying to cheat on the tests.
12 to 14 hours
The best way to pass a test for meth is to not use the drug.
Vyvanse lasts 12 to 14 hours, so it will show up on a drug test... however if you are prescribed it then there should be no problem. Furthermore, it also depends on the type of drug test, and what the drug test is targeting; if the drug test is to test for steroid use, whether you have vyvanse in your system is irrelevant to the test.
All you have to do to pass a swab test is not use drugs for 12-48 hours before the test. Obviously the longer you're clean before the test the better.
