I posted a couple days ago about yoga and transcendental meditation in the church. A friend mentioned a podcast he had downloaded from last month, where the effects of drugs were deemed similar to the effects of yoga and meditation.
After some digging, I found the full audio of that hour:

This segment contains interviews with several hallucinogen researchers and the bits with mysticism are not the complete focus. It is interesting to see the full force of what we are inviting into the church.
