Isn't it also the same with alcohol, at least the beverage that people drink? Wine especially is very susceptible to conditions; soil, weather, strain, location, barrels, harvest time, aging conditions/temperature, etc.
Sure, the alcohol chemical is the same everywhere, but so is THC/CBD when you want to reduce it like that. Watered down ethanol is probably a thing but few people drink it like that.
I used to think so too, but apparently not. Ethanol is chemically the same everywhere, but there are lots of other compounds and different alcohol compounds in booze as well and apparently make a difference in your high and how much your head hurts afterwards.
Still, there is the information inside, that not just ethanol gets produced by fermentation, but also other alcohols and the main point was, alcohol is not the same as ethanol.
Huh. I didn't expect so much methanol to be present in booze! (Methanol is incredibly toxic, but ethanol is an antitoxin, so that explains why wine doesn't kill people.)
That was not my experience at all when I used to drink, and I don't think I'm alone in this. The feeling from different alcoholic drinks differed significantly.
A good portion of drunkenness is purely psychological. Tell people that fruit juice is alcoholic, and they start acting drunk, even though they're sober. I imagine it's mostly that, plus the different alcohol concentrations.
For some people that's definitely true, placebo is a real thing after all. But it's not like that with everyone, and even if "booze is booze is booze" is true, just like with cannabis, there is more stuff in the drinks than just alcohol, that might also change the effect you get from drinking.
