"...they can be addictive." No, this is not true they are actually anti-addictive. In fact there are many studies that show psychedelics are among the least addictive substances known. No withdrawal, no compulsive use-cycle, no dopamine hijacking, and they actually produce tolerance fast so frequent use ends up being self-limiting. Also, saying that psychedelics "alter reality" is a bit misleading too, it reduces the function of the default mode network (DMN), and while this treads into philosophy, one must question what is meant by "reality."
