I don't use marijuana, but I do know that it not physically addicting, but it can be philologically; then again so can soda, peanut butter or and thing else that a person might obsess over. There is a lot of ongoing research on how to use marijuana more effectively as mainstream prescribed medication. I wish we'd just get the legalization process over so the we (tax payers) stop wasting money on enforcing the existing laws, and legitimize reliable sources of distribution so that the drug cartel suppliers take a hit in their bank accounts. Not to mention the tax revenue that can be put to work for us all. In my opinion, everyone who wants to smoke/consume pot are already doing so.
