i thought beta arasone was a carcinogen ?

Thought i may just add my calamus experience - i took 23.5cm of freshly harvested and dried wild gathered calamus rhizome (gathered in south africa)- chewed it thoroghly and swallowed it - after an hour i was sick, after 2 very sick, after 3 i was puking for the next 8 hours till i could puke no more - i almost had to call an ambulance - not kewl - there were mental fx yes but so not worth it. perhaps i ate too much but i had heard that is how much was used to create hallucinogenic scenes.
