So a vaccine for... cocaine?

[Aerozord]

I think I might be more surprised the idea to make a cocaine vaccine even happened.

The novel vaccine Dr. Crystal and his colleagues developed combines bits of the common cold virus with a particle that mimics the structure of cocaine. When the vaccine is injected into an animal, its body "sees" the cold virus and mounts an immune response against both the virus and the cocaine impersonator that is hooked to it. "The immune system learns to see cocaine as an intruder," says Dr. Crystal. "Once immune cells are educated to regard cocaine as the enemy, it produces antibodies, from that moment on, against cocaine the moment the drug enters the body."

its an interesting idea. I'm sure some people will be paranoid but I think this is a net good. I do wonder if cocaine is an exception or the rule. Could they do this with other addictive chemicals, could this be expanded to dietary indulgences?

Though I'm betting there is a limit. Since it uses your immune system to attack the drug you can probably overtax it. This is designed for recovering addicts and not as some kind of method to keep anyone from using the drug.
