I'm just curious as to whether LSA been as researched as some drugs. If there hasn't been a study done on it, I think it would be interesting to see what the outcome would be. (Quick! Stash your HBWR seeds before it gets outlawed)
I don't think LSA has been as extensively studied as LSD or some other Psychedelics but what kind of studies are you looking for ? I found an article suggesting LSA may be effective for alleviating pain associated with cluster headaches. http://www.maps.org/research/sewell_2008_aha_lsa_poster.pdf
I believe Albert Hoffman did some sort of testing on it. Not sure of the extent, but I do know that he tried it for himself and compared it to LSD. Perhaps doing a search on it would turn up more information?
