Generally in an article about arresting or sentencing a drug dealer, people don't bring up that the drug users are actually to blame.

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.

I think that that is actually an oversight. One needs to consider the entire chain. For example, with proper parenting, there would be a lot less youth demand for drugs. It doesn’t make what a drug dealer does any less bad, nor does it make the efforts of the police to arrest the drug dealer any less important. But it’s suboptimal to consider a small piece of a system, without thinking of the whole.
