if you aren't a chronic smoker and have been clean for 3 months, you will piss clean much faster. it could take anywhere from i'd say 4-7 days or longer, depending on quite a few factors. i wouldn't chance it though.
If you've been clean it shouldn't take more than 72 hours to pass a test.
Depending on the substance yes. You need to completely flush your system, diarrhea helps if you cannot buy some anti toxin kit somewhere
You cant
You will pass don't worry. Detection period for weed / saliva drug test/ its 3-5 days.
Rectal seepage
yes you will pass
NO!
from 3-5 days
Nothing, you just quit using for about 3 days before test
about 2 or 3 days with lots of exercise and water
cocaine will show in a drug test for minimum of 3-5 days depending on how heavy an how often you used
about 3-4 months, unless you eat a lot of spice foods
Cocaine and heroin stay in your system anywhere between 3-5 days. From personal experience - if you drink plenty of water you may even pass a drug test after 2.5 days (60hours), but under normal circumstances you are looking at around 3-5 days depending on your metabolism.
I have personally used strip nc 3 days before a drug test after smoking very often and I passed.
