The "by any means necessary" method...? I think a society based around the normalization of this level of punishment is distopian. Achieving the lowest opiate addiction rate possible may not be worth it given the probability of wrongful incarceration/death, its optimising the wrong thing. I think humanity should just accept the multi-facetedness of the universe and work on systems which work without compromising our humanity. We are hooked on mental shortcuts and quick fixes.

Have you seen the opioid and crystal meth epidemics up close? They are far more dystopian than Singapore executing the odd drug trafficker.

Also ban the chewing gum while at it (as they do there).
