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.
The amount of time it takes for the effects to kick in also depends on your metabolism. People with faster metabolisms may feel medicated after an hour, yet people with slower metabolisms may not feel the effects for two hours or more. How Long Does the Effects of an Edible Last? Metabolizing cannabis makes the effects much stronger. Edibles are typically made with highly concentrated cannabis, be it in actual concentrate form (hash oil), cannabis-infused butter, or infused oil.
