There's absolutely nothing wrong with prescribing opioids to people who may benefit from their use. What's wrong is putting the interests of big pharma above your patient. This kind of corruption damages the trust that people place in the medical profession. That's why the doctor lost his license. The article even says:
>You in effect sold your medical license to a pharmaceutical company
The DEA should have nothing to do with this. Treating doctors like potential drug dealers is going to make them extremely anxious about prescribing any kind of drug with high abuse potential. They invested hundreds of thousands of dollars and years of their life on their medical license and residency programs; do you think they're going to risk it with the threat of the DEA busting them? The DEA getting involved is going to directly harm patients with chronic pain (opioid users) and people with ADHD (amphetamine users).
