Use of Nicotine Gums, Tablets and Lozenges: A Review.

Difficulty quitting is best predicted by how much one smoke on a daily basis and smoking within 30 min of waking up each day, both of which are measures of nicotine dependence.

The cigarette is the most contaminated drug-delivery device. If nicotine is largely what the smoker needs, the use of nicotine from alternative sources to sustain smoking reduction could be exploited for long-term harm reduction to the smoker unable to quit.
