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.
Edibles may be strong, but compared to inhaled cannabis, they actually deliver a smaller concentration of cannabinoids to the bloodstream. Ingesting edibles introduces only 10 to 20 percent of THC and other cannabinoids to the blood plasma, whereas inhaled cannabis falls closer to 50 or 60 percent. The effects of smoked cannabis tend to peak within the first 10 minutes and rapidly dissipate over the next 30 to 60 minutes.
