These past two statements illustrate pretty clearly why very little research has been done on this subject. One mention of LSD, or many drugs for that matter, and you have people jumping to two extremes (that have nothing to do with the original topic of off-label treatment / pain-management.

I have no experience, so I can't say who's right or wrong. I just think it's sad that these type of arguments have given some drugs so much of a stigma that it set back medical research in this area for 40+ years.
