Could you explain a few things?
First off, what is the organization of this chart supposed to be; like, why were things put where they were? Is it functional? Or is it pharmacological? Why are tryptamines way in the middle, while other psychedelics over in the psychedelic corner? Tryptamines, psychedelic phenethylamines (incl mescaline) and LSD all act through the same receptors in very similar ways - i'd think they should all be together. Certainly, LSD, Tryptamines, and Mescaline should be closer to each than they are to Salvia, which is an entirely different drug, acting on entirely different receptors to produce very different effects.
Secondly, a lot of people are going to write off this whole diagram because of the ill-informed note at the top; You clearly are opposed to the use of benzodiazepines and mood stabilizers. This is a personal view, which is not consistent with the prevailing medical knowledge nor the prevailing experiences of recreational drug users.
Benzos and mood stabilizers do NOT act through the same mechanism as solvents (also, benzos, mood stabilizers, and solvents are all psychoactive; check the definition of the term. While solvents do not have a clearly defined mode of action, benzos definitely do (allosteric modulation of GABA at the BZD site), and mood stabilizers have known pharmacological profiles, though we don't really understand how they produce the effects they do). Benzos have not been shown conclusively to be carcinogenic (there are reams of studies, some of which show correlation, while others do not, so if there's an effect it's small). Benzos are neurotoxic (particularly the sedative ones), but only with long term use - if neurotoxicity is the criteria for excluding a drug, you should exclude alcohol and MDMA too (MDMA is more neurotoxic, for sure; in lab animals, single large doses produce neurotoxicity, while benzo-induced neurotoxicity takes chronic use). If you're trying to make a chart which will be viewed seriously, you should not use it to promote your personal views on what drugs are evil.
Finally, your fitting all these drugs into a space with only 4 types of effects marked is a gross simplification (where are the dissociatives? The psychedelic phenethylamines (between psychedelic and stimulant, depending on the one in question)?). The whole chart seems meaningless to me.
