I'm guessing he was just joking.I don't do drugs and would rather a world without drugs at all but there was one university that allowed the scientific study of marijuana and no reputable studies have been done on it since it made a tier 1 drug about 50 years ago. So any garbage that is put into a book or documentary about weed is purely assumption and is non-scientific. The data is clear though...alcohol kills around 25k people a year in america at a conservative estimate, marijuana less than 100. So both should be illegal, but one should certainly be illegal.
