I recently viewed The Culture High film and it is available to stream on NetFlix. The movie is directed by Brett Harvey, who previously brought us 2007's The Union: The Business Behind Getting High.
Whatever side you stand on legalization or even decriminalization of marijuana in the United States, the film is worth watching at least once.
One thing did feel out of place - around 35 minutes into the film there was a lone commercial/media report on "synthetic marijuana" depicted with a reporter holding up a package of the infamous Mad Hatter branded herbal incense. I don't understand why it was included. Did I miss something? Maybe an error?
