Do the potential benefits of marijuana use outweigh the risks? This question is the ultimate question that has to be answered within the context of the other real answers. Don’t fool yourself into thinking that there are no risks involved with using marijuana. The risks have been clearly documented over the past 20 years and include the risk of dependency, addiction, brain impairment and even the potential for permanent brain damage. This is all very serious stuff because marijuana is not a benign, harmless herb.
