I have found as of recently that there are ayahuasca groups in just about every major city these days. It's gotten to be quite a popular event in the counterculture. I know this is going to sound insane but try asking a few hair stylists. I guess they tend to get to know people in these types of cultures or something but I know several and I swear every one of them know about it. Seems odd for sure but you may not have to travel out of your country. You could also try doing it yourself if you wanted to.

I takes a little while before you can get out of the nursery. If you are willing to put in the effort and you follow the rules of the site it wont take you long. I know you say you have a lot of experience but honestly anyone can say that. If you contribute to the group here I have no doubt that you will get full membership soon. We look at maturity and responsibility in peoples posts.
