Not a big fan of the ongoing productisation of transcendental, possibly brain-scrambling experiences. Keeping them somewhat less accessible tends to filter out people who don't do their homework to understand the substance and who consider it just another novel experience to try on a whim, which increases the risk of negative outcomes.
I'm of very two minds on this topic. On one hand, it's widely accepted that most (not to say all) drugs leave a permanent mark on brains that are not yet fully developed, so teenagers who are often most curious about these things. Gated access is highly desirable in this context, especially as you can't take self regulation for granted. On the other hand, many of these substances show great promise in many clinical trials for a wide variety of issues, and decades of hostile legislation has kept all of that on the back foot. Openly sharing information about these topics can help people make more informed choices whereas those who came before them often had to go it blind.
