The Oregon Senate has sent a bill that would add post traumatic stress disorder, PTSD, to the list of medical conditions that may be treated by medical marijuana. Sen. Laurie Monnes Anderson says many veterans testified in committee hearings that pot is the only drug that helps ease their minds and prevent terrifying flashbacks to war. Opponents of the legislation say they cannot support prescribing a drug that is still illegal in Oregon. The House will consider amendments written to address concerns the state police have with the plan.
