you don’t see diabetics recommending everyone constantly monitor their blood glucose and take insulin
To be fair, being aware of your glucose level isn’t a bad thing. Insulin is probably not an “everyone” thing but if monitoring blood glucose wasn’t so cumbersome, I would suggest it to anyone. It has similar value to monitoring weight, blood pressure or temperature.
Maybe the term “gateway drug” isn’t a warning for users about their habits but a warning to users about the slippery slope of companies realizing the next drug needs to be legalized and put on the shelf next to weed for more of that sweet, sweet money.
