Will you show show positive on a drug test if you only smoke on ocasion once every few months I took two hits of a joint Im 6 3 190 pounds?

Answer 1

Depends on a few different things:
For somebody your height/weight AND that only smokes once every few months:

The main factor in your situation is the time between those last two hits and your test.
Was the time previous to those two hits a few months beforehand? or days? If it was months, you should be safe within a week. If it was days, maybe two weeks.

Most marijuana drug tests are not necessarily true/false. They measures the amount of residual THC left in your body on a scale. Even somebody that has never smoked marijuana can show a low-but-non-zero reading on the scale. Many things may cause this, for instance, ibuprofen(advil).

For daily smokers, it may take up to 3 months for the residual THC levels to become low enough to receive passing marks on a marijuana drug test. This is because THC (the psychoactive ingredient in marijuana) is fat soluble. Because of this, it gets stored in your body's fat cells. The more you smoke, the more saturated you fat cells become with THC. This is also why heavy marijuana smokers develop a tolerance. The marijuana drug test scale can loosely be associated with the measure of a smoker's tolerance. When a heavy marijuana smoker stops smoking for three months (usually in anticipation of an upcoming drug test), the THC slowly exits from their body. When they return to smoking after taking the drug test, they get much higher from much less marijuana because their tolerance is gone. The same thing happens with many drugs; cigarette smokers develop a tolerance to the nicotine and over time, they need to smoke more cigarettes to feel the same effect as when they originally started smoking.
