Cannabis and Cannabinoids (PDQ®) - National Cancer Institute

It isn't a new study, but an overview of other studies regarding MJ and cancer. The reason why it's notable is because this is the first time a federal organization has admitted marijuana has medical use. More findings like this by other federal agencies will strengthen the case for changing marijuana's status from a Schedule I narcotic to a Schedule 2 non narcotic, which would be a major liberalization of MJ policy.
