And they’re making a fucking mess of the pharmacological and social definitions of “drug”. It’s the propaganda version of that “ackshyually tomato is a fruit, not a vegetable” brain-rotting idiocy.
Depressant, stimulant, those refer to the pharmacological activity; it’ll include even things not socially considered as drugs, such as caffeine (stimulant) and alcohol (depressant). In this sense marijuana is not its own class, it’s THC is a depressant.
That “club drugs” category is a fucking mess in both definitions. Ketamine is an anaesthetic, thus likely a depressant; ecstasy is mostly a stimulant with weak hallucinogen properties, pharmacologically they’re nothing alike. And socially they’re closer to caffeine (as things that you ingest willingly) than to date rape drugs (things that people give you against your consent).
And even the division in social drugs depends on usage. Marijuana for example can be used for clinical or recreative reasons; abuse is of course bad, but frankly I wouldn’t be surprised if most marijuana smokers had better lungs than I do (I don’t smoke weed but I smoke tobacco - nicotine is a depressant stimulant BTW). Same deal with the date rape drugs, alcohol could be used as one.
Aaaaah, sorry for the rant. What I want to convey is that yeah, I get why this infuriates you. It infuriated me too.
