You already touched on it but something that's always in the back of my mind when it's "because drugs" is that the excuse given doesn't even hold its own merit. The implication always seems to be that they're criminals (the dehumanization effect here is strong) and you're supposed to stop thinking critically now. It's incredibly frustrating to me how effective this is with a large population of people.
