I just happened upon this place, Center for Cognitive Liberty and Ethics, while I was looking for information on the dangers of smoking from tinfoil. They seem like they are (or were) onto some good things: stuff about having the right to autonomously use the full spectrum of your mind and multiple modes of thought. Looks like they are a non-profit and lost their funding though. They have a section on Entheogens & Drug Policy, as well as a Journal of Cognitive Liberties. I also want to come back and check out this multi-part essay “On Cognitive Liberty.”
