yo, was reading the stimulants part... there are several that seem to be missing. the legal ones would be nicotine and caffeine. the RCs would be 2,3,4-FA, 2,3,4-FMA, the cathinone family (khat kind of falls in that category), and i would change the 'dexedrine' one because that is a brand name, and replace the dexedrine with dextroamphetamine, and finally i would add levoamphetamine to the stimulants list. its also worth noting that some people find recreational value in diphenhydramine, which is technically an antihistamine but is also a depressant, and at very high doses it becomes a hallucinogen. it may also be worth adding poppy seeds/poppy pods to the opioids list, although the chemicals are roughly the same as those of opium, but the poppy seeds and pods are generally not associated with the latex. just a thought. under the psychedelics section, mescaline and peyote are basically the same thing (mescaline is the active ingredient in peyote). another drug to add to psychedelics (or dissociatives, technically its both) would be ibogaine. in psychedelics, the 2c family has many more drugs, including 2c-p, 2c-e,2c-c, 2c-d, 2c-f, 2c-g, 2c-h, 2c-n, 2c-tfm, 2c-t, 2c-t-7, 2c-se, and more. another couple to add to opioids would be oxymorphone and hydromorphone. another to add, but im not sure where you should put it, would be the kavalactones. another to add to depressants would be the muscle relaxers, namely cyclobenzaprine and carisoprodol. another one to add would be kratom, which i believe belongs in the opioid section. i cant think of anymore at the moment, but i know there are plenty.
damn after all the edits i just added like 20 drugs to that list...
