Now if we're in a discussion around the cartels, plenty of people do bring up (and there's also those that get annoyed by it) that the drug users are actually the ones funding the cartels via their drug use.
Along these lines, I think another fun comparison might be opioid use and Purdue.
eg: I grew up in a very nasty place. My neighborhood had a few pregnant 13 year old girls and a lot of drunks and smokers, including kids in their early teens. My parents kept me away from it all, while also both having full-time jobs. They put a lot of work into filtering whom I could be friends with and where I was allowed to be. THAT is the job of a parent.
