Will exercise clean the body of marijuana?
It will help clean the marijuana out of your system, yes. Marijuana (THC) stores itself in your fat cells, which is why it takes so long to leave your system. Drugs like speed, heroin, cocaine, and Ecstasy stay in your bloodstream, so you can pee them out in a few days, but since marijuana stores itself in your fat cells, you have to work it off — like, burn it off. Exercise burns fat, so it helps get rid of the THC faster.
