No need to be passive aggressive. I think a lot of people care. If you've read my other post you'd notice I said I agree with decriminalization but believe Oregon didn't implement the law in a meaningful way. I don't know if you've lived in an area where there are homeless encampments before but drug use is often a big issue there. LA, Portland, San Francisco and Seattle, all places I've lived in have this issue. So yes, for you this may be a non issue for you but for communities that live with this problem it is a legitimate issue. What do you mean when youre advocating for full legalization? We might not even be talking about the same thing. I don't care about weed, all for legalization for that. Under no circumstances should drugs like heroin or meth be legalized. Are you saying you don't care about people who are at the highest risk for drug abuse and need the most help? That's ideally the place where rehabilitation will help the most.
Feel free to look at the statistics for drug use and homelessness here. https://americanaddictioncenters.org/rehab-guide/homeless
While I agree, the UK needs to chip a little more in too. This is everyone's problem, not just the United States.
