you’re more even keeled. … You don’t get too far up, and you don’t get too far down.” Maine voters legalized marijuana for medical purposes in 1999 and approved a law creating a statewide network of marijuana dispensaries 10 years later. Twenty states and the District of Columbia have legalized medical marijuana use, but only six other states allow its use for PTSD, according to the Marijuana Policy Project, a D.C.-based advocacy group. Gordon Smith, executive vice president of the Maine Medical Association, said the question of medical marijuana use for PTSD treatment is contentious among the medical community. “We heard both from doctors who felt that particularly people coming back from Afghanistan might be assisted (by it), and we heard from doctors who thought there was not a sound evidentiary basis for it,” Smith said. Because the drug is still illegal under federal law, there is a lack of federally funded studies on medical marijuana. That has been a challenge to understanding its impact on various conditions, Smith said. The U.S. Department of Veterans Affairs changed its policy on medical marijuana in 2011 to ensure veterans using medical marijuana in states where it’s legal aren’t punished, said Michael Krawitz, director of the Virginia-based group Veterans for Cannabis Access. But VA doctors still can’t recommend medical marijuana for treatment or provide documentation to get it. McCarrier said he suspects the new law will bring many new patients into Maine’s medical marijuana program, which had more than 1,450 patients registered with the state in 2012. Efforts to expand the program to include more qualifying conditions will likely continue in Maine. The first draft of the proposed law would have allowed doctors to prescribe marijuana for any condition they deemed necessary.
