HOW LONG DOES THC (MARIJUANA) STAY IN THE BODY?
This answer depends on your metabolism, the frequency of smoking and concentration of THC. Even if a person has been clean for a month, they may still test positive on a drug screen because there are still residual amounts of the drug in their body. If a person was a heavy smoker and had a slow metabolic rate, it is more likely that THC will stay in his/her body longer than someone who smoked less frequently, and had a higher rate of metabolism.
