Although there are a lot of unknowns (and I'd fully respect that sort of opinion), comparing a primarily-5HT2A agonist to a bullet in the brain seems wildly exaggerated given the current evidence I know. If you have scientific oriented links that say otherwise, feel free to share them. From what I know, I find this route of thinking rather hyperbolic.
To give another example, ketamine's another recreational hallucinogen; if it also was thought of as akin to a "bullet in the brain" and nothing more, scientists might not have recognized the potential anti-depressive nature of glutamatergic chemicals (as has happened in the last decade or so).
