Myth Busters: Marijuana aka Pot aka Mary Jane aka etc.

[Xelent]

I have always been one to question "conventional wisdom" as it can get you in trouble if you follow it too often. This is an example and I would like if anyone knew the correct answers to my questions.

-How long do you have to stop smoking before it will not show up in a standard company urine test? What about a more advanced one that takes a hair sample?

-Does it matter what kind of pot you smoked or how long/ how much you have been smoking?

For example, if a pot head that smokes every day for a year and stops for a drug test, does he have to wait longer than someone who smoked for lets say a month? A week? Just one day?
