No, of course we shouldn't ban them - just like we shouldn't ban guns. But they SHOULD be much more regulated.
My sister in law is an example. She has back pain, and needs an operation. She got a prescription for Oxycontin. After awhile, it wasn't enough. Went back to the doctor, he added a prescription for Tramadol (sp), as well as the oxy. Still not enough for her, but her doctor wouldn't give her more. Went to another doctor, got duplicate prescriptions (filled at a different pharmacy). Repeated that whole thing several times. She takes a MASSIVE amount of painkillers every day - she's a single mom, drives her kid around. There should be a national network for pills like this - NO ONE should be able to get 8x the amount of prescription painkillers they need EVERY SINGLE MONTH.
