I wrote a report on LSD and the source I used was a Dr which took the drug and recorded and wrote down all the effects that occurred. From the recordings, notes, and the memories he retained he was able to write such a detailed report I felt as if I took LSD. This was a report from a Dr in the 70s.

The question of do they take the medications. I'm sure they have some sort of study that includes taking the medicine for the effects. But that's just a guess and I've never thought about asking or looking into that before. I have doctor friends and I'll ask them this question and let you know.
