If you explore my previous comments and submissions you'll find some information about these matters.
In summary, there are a great deal of published resources about psychedelics, but they tend to be inaccessible to those without a good deal of psychedelic experience coupled with a penchant for reading academic or esoteric literature. Thus, for largely sociological reasons, most 'typical' modern users of psychedelics are not at all schooled in academic knowledge about them. On the other hand, the vast majority of systematizing, intelligent, intellectual types do not have sufficient experience with these compounds to really understand or effectively critique the literature about them.
So I'll mention a few quality sources that, if you study them, will almost assuredly arouse your curiosity:
* The Psychedelic Explorer's Guide (published book)
* The Antipodes of the Mind (published book)
* The Journal of Psychoactive Drugs (not just about psychedelics)
* Tryptamines I Have Known and Loved (published book, of particular edification and interest are the essays that precede the synthesis portion of the text)
* The research done by the Multidisciplinary Association for Psychedelic Studies (MAPS)
LSD has proven itself to be quiet beneficial in social situations many times in my life. For example, while 'up' on a moderate dose of high quality LSD, I watched a very attractive guy play guitar and sing at a house show. This led to me having an amazing fantasy experience days later where I finally started to deeply connect to my sexual desire for other men. This precipitated my decision to affirm my bisexual inclinations and pursue them, thus overthrowing years of internalized shame and confusion regarding this issue.
DMT and other very potent tryptamines have also proven to be potentially valuable in my experience. For example, while under the influence of a powerful dose of an orally administered research chemical tryptamine, I literally was able to relive my previous suicide attempt and forgive myself for such self destructive violence in a very deep and healing way. Words literally can't describe the true magnitude of the experience and the positive after effects are still in my life and personality years later.
Not very often but not infrequently either.
