If you are interested in learning more about psychedelics, and their context in 2018, I'd recommend UC Berkeley Professor Michael Pollan's latest book "How to Change Your Mind". It is a really nice, easy to read primer on the topic, and his experience with psychedelics. He approaches the topic with a scientific yet accessible tone, and he asks and answers lots of good questions. Pollan interviews many of the people mentioned in this New York Times article.
