Upping the ante on his critically acclaimed documentary The Union:The Business Behind Getting High, Canadian director Brett Harvey returns with an in-depth analysis of marijuana policy called The Culture High. 

In its quest to understand what’s really going on behind pot prohibition, the documentary features testimonials from experts and unforgettable characters on both sides of the debate—including undercover agents, representatives of advocacy organizations like Transform and Release, and famous advocates like Snoop Dogg (of course) and Richard Branson. Branson was so enthused by The Culture High that he’s promoting it on the Virgin website.

The Culture High will be released in the US on October 17 but you can check out the latest trailer below:
