People who use the nicotine lozenge are twice as likely to quit and stay stopped.
When using the lozenge you take in less nicotine at a much slower rate than when smoking. This makes it less addictive and easier to stop using than cigarettes. However, it will be several minutes slower at easing cravings than a cigarette. The mini lozenge dissolves faster (10 to 13 minutes) than the lozenge (about 20 to 30 minutes). Over a day, lozenge and mini lozenge users typically absorb somewhat more nicotine than from similar doses of nicotine gum; that is, over one-third (2mg lozenge or 1.5mg mini lozenge) or over two-thirds (4mg lozenge and mini lozenge) of the dose of nicotine that they would get from smoking a pack of cigarettes per day.
The 4mg nicotine lozenge also appears to reduce weight gain that may occur after quitting, but doesn't have a lasting effect beyond its use.
