Nicotine Lozenges first appeared on the retail market in 2002 as another form of nicotine replacement therapy (NRT). Other forms of NRT include: nicotine patches, nicotine gum and nicotine nasal sprays.

The nicotine lozenges are meant to be sucked slowly until they are fully dissolved. They can be chewed which will release the nicotine faster but this method of ingestion has been known to cause heartburn or indigestion.

Nicotine lozenges are meant to be only a temporary measure in the battle to quit smoking and should be used for no longer than 12 weeks at a time.

Some of the side-effects associated with using nicotine lozenges include: sore teeth and gums, indigestion and irritable throat.
