The movie is called The Union: The Business Behind Getting High
http://www.imdb.com/title/tt1039647/

Its a documentary about pretty much everything about marijuana, its history, politics, medicinal uses, its uses as hemp, and about the business of growing weed illegally.

If you have a mom who doesn't like you smoking weed, make her watch this movie.

Watched this a couple of weeks ago. Really well done documentary, covers pretty much everything well with backed up claims and explanations.

If anyone is still against legalization, or even medicinal after seeing that guy with ms, they would have to be retarded/christian.
