The preference for sucrose solution in control rats was also lost in rats chronically treated with 0.16 mg/kg LSD, indicating a state of anhedonia in these rats. On the basis of these results and their earlier studies, the authors suggest that rats chronically treated with LSD may represent a new animal model of psychosis, with the advantage that the animals can be used long after the LSD treatment has been ended. Recently, the term entheogenic has come into use to denote the use of psychedelic drugs, as well as various other types of psychoactive substances, in a religious, spiritual, and mystical context.

When serotonin receptor–selective antagonists became available, it was Glennon et al. who demonstrated in a rat drug discrimination model that the 5-HT2 antagonists ketanserin and pirenperone blocked the discriminative cue of a Psychedelic . Further studies in numerous laboratories over the next 2 decades, primarily with rodents, then focused attention on the 5-HT2A receptor as the primary target for psychedelics. Agonist or partial agonist activity at the serotonin 5-HT2A receptor was ultimately concluded to be a necessary pharmacology for psychedelic effects, but it may not be sufficient to explain all of the qualitative differences between different drugs.
