Confuse a druggie, stop an addiction?

It could be the case.

Researchers temporarily disrupted the jonesing of drug-addicted rats by interrupting their drug-related memories.

Of course, it took another chemical to do that, meaning that this is of little real-world value, at least right now, and by itself.

Now, as part of a whole-spectrum package of treatment? Yes. But, even then, the addict has to be willing to follow the protocols involved, which gets back to willpower and willingness to change.
