I watched this documentary last night and it basically was a story of a chimp that humans abused for 20 years. The only one of them that he forgave was the one he would smoke weed with in the 80's. They were trying to study human language in apes in the 70's and ended up discovering a connection between weed and relationship communication. Even though the film didn't recognize that, I couldn't help but notice the evidence. Check out the film and tell me if I'm crazy.
