Intrastate mj regulation is now under the control of states, as it used to be and should have been all along per the Tenth Amendment.
Prohibition does not work. This is good news for a free people, in spite of the hysterical claims of those that learned everything they know about marijuana from an old episode of Dragnet.
Believe it or not, my county's sheriff was quoted about a year ago in a local morning paper that the "suspect" in question was all "hopped up on Marijuana". I blew coffee out my nose in laughter when I read that one. Not a fan of legalization, but I wonder how much of the mania around MJ is perpetuated by certain dupes in law enforcement.
