Best Answer: Marijuana remains in your system for about 14 to 30 days. However, hair follicle tests typically detect THC (marijuana) for up to 3 months after you have quit using. Since THC (marijuana) stores itself in your fat cells, exercise -- especially fat-burning exercise like weight training and intense cardio -- can help get it out of your body faster.
Also, it stays in your system for much longer periods of time than any other illegal drug. On average the weed will be stay in your system between a week and thirty day. However, in some extreme cases thc has been detectable in the body (urine and blood) for up to 180 days.For a hair drug test marijuana can stay detectable forever until that hair is cut.or a first time pot user, thc will remain detectable in the system for a period up to 7 days. For some casual weed user who have smoked weed 2-3 times each week, thc can be detectable for a period up to 21 days. Chronic users who smoke pot everyday can expect to excrete thc toxins for up to 90 days.
