I'm a psychiatrist and I work with an addiction population. I think many of them would be glad to have this as an option. It's certainly not perfect, but it would provide an additional layer of protection to people who struggle to maintain sobriety. I think it's sad that the first reaction to this is to think of it as something from "dystopian" science fiction. The oral medication disulfram shares a similar mechanism…
I hope you're right. I used to be a heavy smoker and even after I cut back I was still addicted to nicotine and unable to give it up completely. Eventually I was prescribed Chantix (which was still fairly new at the time) and took it in hope rather than expectation. It worked - to such an extent that it was like a time machine for my brain, unwinding it back to an earlier stage before I had overcome my dislike for the smell and taste of tobacco. Every day that I wake up without the taste of yesterday's cigarettes or draw a deep breath I feel grateful for it's availability; it was easily the best $400 I ever spent.
I hope this offers a similar benefit for people in the grip of alcohol addiction, a much heavier burden than the one I had to cope with.
