OK guys, I got him to answer some questions, so make them good. We will be verifying him as well. He will be available between around 6-8 PM each day for a few days, so don't get impatient. Post your questions, and we will try to get them answered ASAP.
Some background info on Rick for those who don't know who he is. Here is a Wikipedia link. Here is a link to a documentary about DMT and a quick little trailer with him in it. And here is his web page.
He is obviously most interesting for his work with DMT. Ask away!
