At the end of the day, the "experience" of using a substance exists entirely in an individual's mind, and I believe one way to be constructive with one's personal experiences (in general) is to effectively communicate them to others in hopes that they can generate positive discussion.
I think that communication is what makes life so great, and when it has to do with how something has improved or even harmed our lives, it can be helpful for others to make decisions, but yes, ultimately your own research MUST be done before undertaking significant risk.
Always interesting to hear anecdotal experiences of others with psychoactive substances. I have dabbled in a few that you have listed so I am excited by the balance of novel and familiar topics you plan to discuss. I love to laugh :)
