i belive that the safest way to deal with Bufotenine are smoking it or sniffing it.
Injecting or ingesting it may be very dangerous stuff.
I have read too that arundo leaves have a toxic glycosides which can damage the heart.
i am very interested about details of this experience, could you tell us??.
"Still, I know of at least one person who had a very strange and very psychedelic experience using A. donax rhizomes with [admittedly a large dose of] P. harmala seeds".
How many gr of arundo roots did your friend use?.
how many gr of peganum seeds?.
