The vast majority of quitters will relapse. That's already known. Well established, in fact. That's what "highly addictive" means. The median number of quit attempts before success is 7.

So it's unclear what usefulness this prediction will have. If it's accurate, it'll tell us what we already know: pretty much all quitters are at risk of relapse.

What's useful: advise quitters that relapse is not the end of the world, that the number one predictor of success is how many times you've tried. Don't give up giving up.

The brain events add nothing to that.

And the woo-woo future pharm has failed to arrive for 50 years. Don't wait for it.
