I just saw this list on reddit and had only seen The Bridge out of them. To be honest, reading the descriptions, I'm not really in the right mindset to watch any of the other at the moment, but they may be of interest to others.

2. The Scariest Drug in the World
Scopolamine is a drug that when taken keeps a person coherent but makes them open to follow commands. It’s been used to make people steal, as a rape drug and a way to humiliate people. It’s known as a “chemical hypnosis”. This film documents people’s experience with it. Link:
