Yes, don't ask why and it was the worst thing I've ever put up my nose but a long way, I reckon it took 4 days to get over, DO NOT DO IT
Hated the stuff as well, I needed it for a while at the time but I wouldn't recommend it unless your having serious mental health issues, it has absolutely no recreational value IMO.
I was on the stuff at the time so if your asking about the effects of Chlorpromazine (Thorazine) it juts shuts you down mentally, depending on the dose the effect just gets stronger, I wasn't on a high dose (50mgs daily in the end for a while) but even that made me significantly less functional all round, just not really thinking, at higher dose there is a shuffle and a mask like look that seems unique to the drug.
I believe it now use instead of ECT and actually lobotomy and was responsible for the emptying of many and old style asylum, whether it was to the benefit of those patients I could say.
