DENVER (AP) — Hundreds of military veterans received free marijuana during a special giveaway in Denver designed to show that pot can help ease their pain. Members of Operation Grow4Vets said the Saturday event aimed to offer veterans an alternative to prescription drugs to help with anxiety, pain and other problems. Colorado this year rejected marijuana as a treatment for post-traumatic stress disorder, so the condition is not on the list of ailments for which doctors can recommend medical marijuana. Bob Doyle of the Colorado Smart Approaches to Marijuana Coalition said organizers of Saturday's event were reckless to give away a drug that can also cause paranoia and may have other unforeseen side effects.
