Not sure what's ironic about it? At least in the usual definition.
It's been a huge problem up here. Baltimore and a lot of MD is struggling w/ heroin and ODs from Fentanyl lacing have skyrocketed. One can say, "well that's a problem that will cure itself in time once they all OD", but the problem is that the dealers aren't the users, and there's lots of folks who are just trying to get by w/ "maintenance levels" on the road to recovery and don't know their getting a huge hit instead.
