Quitting smoking is tough, so tough that only about 5% of smokers who try to quit in a given year actually succeed.

Medications can double those odds, which still leaves a high failure rate.

And a promising vaccine, meant to arouse an immune response

to nicotine, couldn't beat a placebo in clinical trials. But researchers haven't given up on a vaccine

just yet. Instead of revving up the immune system, though, they've come up with a new idea. Why not

use an enzyme to break down nicotine before it gives you a buzz?

Almost 50 years have been reports of bacteria that can actually use nicotine to thrive on.

Kim Jonda, a chemist and immunologist at the Scripps Research Institute.

The bacteria uses nicotine as its sole source of carbon and nitrogen.

It does the trick with a nicotine chomping enzyme,

so John De and his colleagues added the enzyme to mouse serum, doped with a cigarette's worth of nicotine.

The enzyme was stable at human body temperature, and it was able to cut the half-life of nicotine from

a couple hours to less than 15 minutes. That is, it greatly accelerated nicotine's disappearance.

The study is in the Journal of the American Chemical Society. But Jonda says the enzyme isn't ready
