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.
For this reason, when you ask âHow long does marijuana stay in your system?â you have to realize that itâs very unlikely that youâll be able to get a usable answer. The most common period of time is anywhere from 3-30 days, depending on your metabolism and the amount of marijuana that youâve smoked.hen you ask the question âHow long does marijuana stay in your system?â you need to take into account the fact that there is no simple answer to this question. THC (Tetrahydrocannabinol) can stay in a person's body for as long as 3 to 90 days after smoking or being ingested orally.
