The idea seems simple enough.
Preserve all the rituals of smoking: Light up a cigarette, inhale the smoke, including the nasty stuff that can kill you, and exhale. But remove most of the nicotine, the chemical that makes tobacco so darn hard to quit, to help smokers smoke less.
The Food and Drug Administration has been contemplating that strategy for at least six years as one way to make it easier for smokers to cut back, if not quit entirely. Less than two years ago, it authorized 22nd Century Group, a publicly traded plant biotech company based in Buffalo, New York, to advertise its proprietary low-nicotine cigarettes as modified-risk tobacco products.
