Once they start cracking down on the pill mills over in fla.. (I believe they've already started) Heroin will then become an epidemic in that state. Just like pretty much every other state.
They already started cracking down on it a few years ago, probably in large part due to that documentary called 'The OxyContin Express' which showed how easy it was to Dr shop, and how many people were dying as a result. Once they started taking down the pill mills they got pretty extreme with the restrictions of the prescribing of oxy, to the point where it was very difficult for even legit patients to get their prescriptions filled since a lot of pharmacies stopped carrying products containing oxycodone. So since then the dope started taking over, so that's pretty much old news.
