The only definite way that i know of is just to not use marijuana at all.
Dont do drugs =)
Really easily. Don't smoke it
My answer would positive because marijuana is the main dangerous drug which can ensure other in the category .
No
No
No. THC is marijuana
yes ! not in a normal blood test , but if a drug test is taken it will show up as positive however it also depends when or how long ago did she do the drug before the drug test
yes it can be a false positive.
No.
I'm assuming you mean THC, Tetrahydrocannabinol, which is the chemical in Marijuana. So marijuana is the only drug that will test positive for THC.
Using someone else's urine, who has used pot, for the drug test would give a false positive.
A very small amount of marijuana can show up on a drug test. Most companies will allow a small amount of up to 20 ng to show up on a drug test and not test positive.
Tetrahydrocannabinol aka THC.
If the test is for steriods it will. If the test if for other drugs (cocain, marijuana, meth, etc) it will not.
