Did hallucinogens have any impact on you longterm?

Yes, they can: Long-term lsd effects include ongoing psychosis and hallucinogen-persisting perception disorder (hppd), or "flashbacks." psychosis with hallucinations & mood swings can continue years after the trip. Hppd has visual disturbances like seeing false motion on the edges of the field of vision, bright or colored flashes, and halos or trails attached to moving objects. This can persist for years also.

Longterm benefits &: Hallucinogens are powerful medicines. Some people have "bad trips" leading to psychosis & ptsd, but research suggests it is much more common to have lasting positive benefits including "self-realization", stronger spirituality, greater longterm happiness, compassion & patience.
