During his campaign for US Senate, "Medical cannabis should be treated like any other medical treatment that saves lives or eases pain and symptoms. In a land of freedom and liberty, that decision is best kept between a doctor and a patient. That is what I believe. That is how I will vote in the Senate. That is how I have voted in the House. I am a firm supporter of the Constitution's 10th Amendment states' rights provision. As such, medical treatment decisions are not the federal government's right to dictate. That decision should be left to state governments, their elected officials, doctors, and patients."

"We're going to have a test case that will help us better understand what the effect of the legalization of marijuana is... For example, student test scores: are the test scores going up or are they going down?... There's no way in the world that I have the kind of experience that the President of the United States has with alcohol, marijuana and other hard drugs. He's got personal experience. I don't, with those kinds of very dangerous substances." http://www.waff.com/story/24512779/mo-brooks-says-legalization-is-state-issue-not-federal
