Saliva, urine, blood, yes you will pass. Concerning your hair, you will not pass. Also, testing positive for marijuana has a lot of different factors, from the amount of consumption, potency of the marijuana to height and weight. To be sure, use a home drug test kit you can find at Walgreen's or CVS, use the first passing of urine that day.

No supplement, exercise or "trick" will help you pass a drug screening. The only way to pass is to be clean. No remedies are worth the time or money as they do not work. Flushing your system, Golden-seal etc are ineffective. I suggest that if you need to pass a drug screening that you abstain from all substances for at least one month before the test.

Unlikely. THC remains in the blood 3-90 days depending on all sorts of factors. It can remain in the hair for up to six months.

You can try drinking alot of water to 'flush' your system a little (it won't make a massive impact). You can also try exercising to sweat it out (again this will be a minor improvement).

I would advise stopping smoking at least 3 months before any major drugs test. It is the only way to be sure sadly :(.

In most cases,marijuanatakes a month to be removed from the body and traces can be found in blood and urine until that time or even later. The only way to guarantee to pass a drug test is not to take drugs in the first place.
