No, you got your drugs mixed up. Methamphetimines(sp) will cause your teeth to rot. I saw the news report on it last week. I guess that's not good news in the Applachian mountains. Now, the cops think everyone is doing meth! Hydro only effects your hearing if you take it too often and too much sort of like Rush. What did you say?
That's what I know or don't know. If someone has the facts and they aren't the same then I'll change my story.
