Preamble

For as long as there have been people, there have been people who altered their own consciousness. The practice is older than any government that has tried to end it, and it has outlasted every one of them so far.

The last century made an exception of this ancient thing. It criminalized a category of experience, imprisoned people for the contents of their own minds, and called the result public health. That era is closing. What replaces it has not yet been finalized, and it is being decided now in legislatures, in licensing boards, and in the business plans of companies that did not exist ten years ago.
