The people I know who are using it are buying it as tablets and gummies that come in 1mg increment doses, and taking exactly as much as they want to have, which typically isn’t much.
Vape pens are presumably also more consistent and predictable, and seem to be taking over. I can’t even remember the last time I smelled actual weed smoke.
It actually strikes me as much more healthy than alcohol culture, where dose control can still be a problem because it’s hard to tell how many units of alcohol the bartender put in your cocktail, and driving home afterward is still quite normalized.
