Which Form of NRT is the Most Flexible to Use?

The gum can be used either as part of a fixed programme or on a more ad lib basis whenever you feel like smoking. The inhaler can also be used this way. How you puff on the inhaler allows you to alter how much nicotine you receive. The patches offer less flexibility than the other two forms. You can only apply one patch a day but the patches do supply a more steady level of nicotine to the body.
