I have an ill family member and as a result got involved with NAMI in 2006. I am now the State director for a 12-week course called
Family-to-Family which has the goal of helping families understand mental illness better and give them communication and problem solving skills. An educated family isle. From teaching this course at least 15 times now, and interacting with hundreds of family members, I am convinced that pot is NOT harmless but does in fact facilitate psychosis in young people.
At every fatal car crash involving marijuana in Colorado and Washington, a mile 420 marker should be posted. Funny how if a state violates Federal laws regarding abortion or gay marriage, they are censured by the Courts almost immediately. Somehow it is different if they contradict Federal drug laws.
