>> Whether legalization will provide a net health benefit for American citizens is still a point of contention.

Might end up with a few less killed violently. Might end up with more money to spend on social programs instead of militarised police. Might end up with much more tax from economic activity brought out of the black market. Might end up with less contaminated produce.

All of these could end up being better for the health of American citizens.

And even if not you're bringing your problems in-house rather than shipping them off to poorer places and causing suffering there.
