>Seriously addictive drugs being sold OTC
Nicotine is one of the most addictive substances in existence and it is sold everywhere. If governments actually cared about addiction risk, a whole lot of things would have to disappear from normal stores.
Governments have spent considerable effort on it, but it's tough to ban something as popular as tobacco or alcohol.
Voters tend to get what they want, and a sizeable fraction of voters smoke or drink.
Nicotine is far more regulated and generally won’t lead you to pass out behind the wheel of a car or drown in a hot tub. You can’t even smoke in the vicinity of many buildings, but kratom? It’s basically an unregulated opiod that anyone over 18 can get and use wherever, whenever, with little to no control over what’s actually in it because it’s not food, medicine, etc.
You have to provide ID and be over 21 to purchase nicotine. You can't advertise nicotine products. You have to be licensed to sell nicotine products.
Same for alcohol. Restrictions on who can buy, who can sell, and how you can advertise and market.
These are not the same as some random pill from a gas station sold to anyone with cash with zero regulations, safety, restrictions, or even any requirement to tell you what's actually in it.
