Will "Big Marijuana" become the next "Big Tobacco?"

Three more states have legalized recreational marijuana.  It will be on additional state ballots in the future.  As indicated in a post below, the health and market risks of these moves may be underappreciated.  The libertarian in me applauds the move.  My cautious libertarianism gives me doubt.  Although the analogy may not be appropriate, if you deplore what big tobacco did in this country, what will "big marijuana" do?
