As someone who believes in legalizing all drugs and in general "personal freedoms", I'd add recreational drugs to this list.

The demand will always be there but there should be strong incentives to not incentivize use (e.g., the Purdue Pharma debacle). We're better served by having these markets addressed by legit players rather then criminal cartels.

I'm not sure what the best solution is, but unfettered promotion to consume is not the way.
