I've watched both of the episodes, I thought the 2nd one on ecstasy was better. It's nice to watch a program which isn't just negative propaganda, and the mdma therapy part was really interesting. I hope they keep looking into the positives of using it in therapy, could help a lot of people out!
I wish they'd gone more into how although ecstasy can be fatal, 40 deaths a year really isn't that much out of an approx 500,000 people popping pills in comparison to the mortality rates of other drugs.
