I didn't get a chance to listen to that. One big factor that lead to LSD crackdown in Canada was the now mostly forgotten death of Benji Hayward in 1988. Before his death buying LSD in downtown Toronto streets was quite easy, his death led to a huge crackdown on street sales of acid. It even helped contribute to the death of Yonge St as a mini Times Square, the porn shops and head shops and massage parlors gave way to gentrification. It's amazing that one single death from misadventure was exploited by the media and government and law enforcement and downtown business interests so effectively. In the time it took to hold inquest into his death something like 90 young people died in alcohol related mishaps. I don't think there will be legal psychedelics in Canada any time soon.
