MasterBaker - how was your experience on 30g? My friend who has experience with other psychedelics was planning on trying 50g for his first dose. Is that a good starting point, or is it too high/low for a good first experience? He doesn't want to overdo it, but he doesn't want to go through all the trouble of eating the powder only to find out he dosed too low, either. While on the subject of doses, can doses of powdered San Pedro be correlated easily to dosage suggestions on Erowid or elsewhere for pure mescaline, and, if so, what's the approximate mescaline content by mass of the powder?

Also, how often can San Pedro be taken without health risks or tolerance lessening the effects?
