How NicoDerm works.
       NicoDerm CQ patches provide nicotine to your system.
   They work as a temporary aid to help you quit smoking by
   reducing nicotine withdrawal symptoms including nicotine
   craving. NicoDerm CQ provides a lower level of nicotine 
   to your blood than cigarettes, and allows you to gradually
   do away with your body's need for nicotine. 
 
       Because NicoDerm CQ does not contain the tar or carbon
   monoxide of cigarette smoke, it does not have the same health
   dangers as tobacco. However it still delivers nicotine,
   the addictive part of cigarette smoke. Nicotine can cause side
   effects such as headache, nausea, upset stomach, and dizziness.
