Feel free to be loose with your definitions. “Not usually considered a drug” is fine to qualify as “non-drug”, for instance. I’m not really thinking so much of “foods”, though, but maybe “food ingredients” and substances found in food ingredients are fine, especially if they’re quasi-drug-like or if you’d get a lot of the same benefits/enjoyment from it consuming it straight rather than in food.
Also ITT, tell other users why their substances actually are drugs actually.
Mine:
- Chamomile - good for my mood and gives me vivid dreams.
- Capsaicin - I and Wilbur Scoville are well acquainted.
- Cacao - I don’t really do cacao any more because I’ve quit caffeine, but I include it here because I still miss sucking on unsweetend baker’s chocolate daily.


I’ll push the boundary somewhat and nominate bitters. I enjoy bourbon and bitters, as in an old fashioned without the sugar. Earlier this year I purchased some Orinoco bitters, which are spiced - think cumin and cardamom. I’ve been alternating the tropical fruit flavours of the more traditional Angostura with the Orinoco. I must get my hands on some citrus bitters too.
