Medical Marijuana Argument in Washington -- Litigation Coming?

Medical marijuana patients in Washington state are allowed to have a 60-day supply of medicine. A process to define what that means in practical terms, overseen by the state Health Department and based on expert input from doctors, researchers, and patients, was going just fine until Gov. Christine Gregoire stepped in, apparently trying to override science with politics. Having tossed out science-based recommendations in favor of a political compromise, it now seems the mess is only worsening and may even lead to a lawsuit. Why must it be so hard to base health policy on facts and data rather than posturing?
