How long does marijuana stay in your body

Marijuana, not being a water soluble drug, is stored in the fat cells throughout the body. It has, therefore, a relatively long elimination half-life of 3-4 days. This may be further lengthened up to 13 days depending on the frequency of usage and quality of the weed.

Therefore, it can be said that although one joint is expected to be eliminated from the body 16½-22 days, for frequent users of pot, this timeframe may go up to 72 days.
