A religion made up solely of heightened religious experiences would not be a religion at all. …The major religious traditions address the mysteries (with or without entheogens), but they have other business to do: widen understanding, give meaning, provide solace, promote loving-kindness, and connect human being to human being.

Entheogens are not to be lightly trifled with… However, if taken with the right attitude and in the proper setting, psychoactive drugs may produce religious experiences. …it is far less clear that they can produce religious lives.
