As I mentioned in my earlier post from last year I experienced LSD and Psilocybin Mushrooms a lot in my earlier life. Extreme conditions during the formative years created a lot of traumas and I have no doubt that those psychedelic experiences help guide me out of some pretty dangerous and life threatening circumstances. But I understood that it was just a tool and not a replacement for enlightenment and like all tools they to must be let go of at some point on the journey. We must be careful about "disregarding" the relevance of these types of tools yet we must also be intelligent about them and not fool ourselves into thinking that they will take us all the way to enlightenment not to mention the negative side effects if they are abused or taken in the wrong circumstance around the wrong people.
A couple weeks ago I was listening to Ken Wilber interview a very well known American Zen Master who was a student for years of a very well known and world famous Zen Master from Japan. The American ZM had been involved in the LSD scene in San Francisco during the late 60"s & early 70's. After he became a student of this world famous ZM he discussed his LSD use with him and he was very critical of it. One time at a group meeting with this world famous ZM, the American ZM asked his mentor if he could ask a question of the class and his mentor said yes. He asked the class, which was almost 80 students, how many of them felt that LSD use was why they had become interested in ZEN Studies and meditation? 62 of the 80 raised there hands in agreement. The world famous ZM never criticized the use of LSD again. Obviously, the American ZM who was just a student at that time eventually stopped using LSD and went on to become one of the most well known Zen Masters on planet earth.
In reading some of the posts on here I can see that there is some bias and judgement going on and that can be as detrimental to ones spiritual development as believing that LSD is a panacea for enlightenment. I have had many people over the years ask me to guide them through an experience yet I turned them down because I felt that it wasn't right for them. It has a place but not for everyone and certainly not for extended periods of time and some shouldn't never go near it.

Best wishes to all!
