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.
However, if you consume pot-infused edibles, the effects of eating weed start only in half an hour or even later. But when THC is finally absorbed by the liver, the weed high can last from four to eight hours. So, just keep in mind that: The effects of smoking pot flowers last 1-3 hours. The effects of eating weed edibles last 4-8 hours. Here is one interesting fact: teenagers experience the marijuana high longer than adult users. Scientists explain that the teen brain has more places for the marijuana compounds to land, so the effects of smoking weed last for more extended periods of time. Does Marijuana Cause Hangover?
