I was first introduced to the article entitled Observations on the Habilitation of Children with Cortical Visual Impairment as a subscriber to the Journal of Visual Impairment & Blindness (JVIB).
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.
Not Worth the Risk. How long marijuana stays in your system depends on your body and health, the amount of daily use and how long you have been smoking. Heavy users will find that pot can be detected in their system for weeks, while lighter users will have it run through in a week.
