I do Crisis Intervention for the Haight Ashbury Free Medical Clinic's special division, Rock Medicine. (http://www.rockmed.org/spaceten.htm ) I specialize in dealing with intense psychedelic reations (bad drug trips) and a few years back we experimented with acupuncture, mainly auricular. Of course, TCM has no specific advice for someone on a bad acid trip, but using metaphors to psychosis, some protocols were developed. We had to stop because it walked a fine line in the law. Acupuncture is invasive since it breaks the skin barrier and you need some sort of permission to do that, which your not going to get from someone tripping on acid (actually you might but it would be valid.) It was a shame, because we were having some success with it.
