I've been looking into ayhuasca as i may be able to get it soon. Now from what i've found out it uses a MAOI to stop the DMT from being broken down. Anyway
i've read that some foods can become poisonous.
http://www.magicalshrooms.co.uk/ On this site click order, then Ayahuasca, at the bottom of the description is a link to a page on MOAI.
The site uses some kind of script so i can't link straight to the page
The relevence of all this is MDMA is on their list of dangerous substances when taken with an MAOI.
I suggest lots of research. Good luck
Edit : Just noticed that Zoloft is on that list.
