But the point is that the US don't prosecute (and persecute) obese people and supermarkets, because health problems are not criminal matters. That's where the difference is.
The US doesn't treat obesity or addiction, or we can say they treat obesity and addiction exactly the same.
Also, "the US don't ... (and persecute) obese people," in just a few moments I can find plenty of people claiming otherwise.
Yet, you can't arrest an obese person for possession of Big Macs. You can't bust them eating a rasher of bacon mid-bite and throw them in a cage.
So, addiction to drugs _is_ a criminal issue. They are not treated in the same way. That needs to change.
If we outlawed you we could turn around and declare you an illegal and use it to justify the law against you. Why won't you just turn yourself in and end the manhunt? With that sort of circular logic in play it becomes obvious that our court system is actually just welfare for people in blue shirts.
