I know that this story is about two years old, but there is talk of reviving this bill in light of the Zohydro (non-tamper-resistant hydrocodone ER).
There are several problems with tamper-resistant opioids:
1) tamper-resistant opioids don't always work as well (or at all)- they're tested on healthy people who have an easier time absorbing them (the healthy people have to absorb them within a 30% tolerance)
2) they don't stop people from abusing them, but it does weaken the "high", which causes them to go to diacetylmorphine/diamorphine/heroin
3) they increase pharmacy prices, which makes it harder for pain patients to afford their medications
3b) increased pharmacy prices lead to increased street prices, which causes addicts (& sometimes even pain patients) to switch to heroin
3c) street heroin has unknown potency, unknown impurities, & poor oral absorption causing people to resort to intravenous injections
The ONLY way to reduce the harm caused by drug addiction is to switch from the law enforcement model to a treatment based model and to LEGALIZE ALL DRUGS (private prisons and the DEA would lose money, so they spend a small fortune fighting this). Legalization (& the drop in prices that this would cause) would eliminate the violence, crime, and disease (people inject heroin because it HA poor oral absorption & injecting is cheaper- same high from less drug; legal drugs also lack the dangerous impurities found in street heroin).
