I’m sure you’re aware of the concept of “set and setting.” The environment can greatly influence the character and content of a psychedelic experience.

Mind control can be as simple as attaching trauma to a particular ideology, or invoking a spiritual experience with some specific subject matter.

I think it could probably be done although it would be wildly unwieldy and unethical.

Not necessarily. LSD reduces the influence of implicit priors. What gets reintegrated depends on context ("set and setting").
