Effective general overview of the state of US marijuana reforms as of Fall 2015

I am giving a lecture this afternoon to a local bar association about the state of marijana reform in Ohio and throughout the United States as of Fall 2015.  Helpfully, this recent article from BloombergBNA provides a useful national overview with a number of state-level specifics.  The piece is titled "Marijuana in America, 2015: A Survey of Federal And States' Responses to Marijuana Legalization and Taxation," and I recommend it for those looking to get up to speed on a lot of the legal and tax basics ASAP.
