That video was fucking ridiculous. It really does prove that people should research more into the way psychedelics and drugs in general work on your brain, and also look into how they think they may respond to the drug based on their own mental mindset and others' personal experiences, before they consume the drug. Under no circumstance should it be taken spontaneously at a concert or at a party with no previous knowledge of the drug - that's just asking for it, and fear would obviously be a response to the unknown. And also that some are not meant to take such heavily mind-altering drugs in general; their mindset from an early age has been to cling to the "truths" of reality.
