Hi-
I got my brother to roll with me on
my bday, and it was a beautiful transforming experience. The absolute best personal experience piece on MDMA was written by an annonymous author in 2001. It's a long read, but everyone I've ever shown it has wanted to roll after reading it. It was published in The Guardian.
Simply google: confessions of a middle aged ecstacy eater
I'd just ask him to please take 30 minutes to read the article to understand what MDMA means to you. I wouldn't approach it as "read this and you'll want to roll!" lol, he might be defensive.
I really hope you convince him to share the experience- i would love to hear how it goes. Much luck and love to you.
