Tell me what are the negatives you've heard about. Scientist are doing a study were they are giving terminally ill cancer patients LSD, to help them cope with their means to an end. 90% of patients have stated that they now feel much more comfortable about dyeing after their experience with it. A professor conducted a study asking college students to describe the importance of their experience after they were given LSD during a study in the 60's and the students described it as a life changing experience that's just as important as the more important things in their life, such as the birth of their first child, or the first death they've experienced, or graduation. The way it changes your thought process is something that is indescribable, unless you've tried it. LSD latches on to your serotonin receptors once ingested, and these receptors are the most important ones in your brain. Serotonin is the reason you dream, the reason you feel happiness, sadness etc... The visuals that come along with LSD are just a perk along with the many other things it has the possibility to do.
Scientists are now experimenting with other inactive analogues of LSD to help battle depression. They find it's better than the sh!tty anti-depressants the governments putting out now.
