I don't suggest anyone attempts to get a pro massage while high (LOL)- it puts the massage therapist in a legally bad position, obviously. I once had a client who felt comfortable getting high before his session with me (he had seen be sober a couple times), and he told me way too many details about his life, how great he thought I was, and asked me a string of very personal questions. I had to ban him from coming back, and I'm sure he felt embaressed afterwards, but as much as I adore MDMA- no one wants to put their professional career on the line for it.
I think getting a good massage at a rave/event/home/wherever while rolling would be best- the music and ambience contribute, and when you're rolling you really don't need someone extremely skilled getting your knots out or targeting a sore muscle- you just need someone that knows how to make you feel good. =)
