Lots of people (but hardly all) who've dropped acid or ingested mescaline are sure they've had a mystical experience, seen God, or the like, and say it changed their lives.

What do we make of that? Some possibilities:

1. It doesn't take much to light up the "god part" of the brain.

2. God operates through the "god part," but people can't tell the difference between God's influence and a chemical reaction in the brain.

3. Since God set the brain up that way, that's how He wants it.

4. Some people have religious experiences on drugs that they can't have ordinarily. Since God set the brain up that way, that's how he wants it.

5. It's impossible for people to distinguish between an experience of God and the chemical effect of a drug - except that people who experience God without having taken a drug know that they haven't taken one.

6. Perhaps all experiences of God are illusions generated by random neurochemical activity that is much the same as what can be induced by drugs.

7. Perhaps experiences of God are genuine, whether induced by drugs or not. If so, God must want some people to have those experiences, even when they're artificially induced, but doesn't want others to have them under any circimstances.

There may be further possibilities as well.
