Nicotine replacement therapy

Nicotine replacement therapy (NRT) is a medically-approved way to take nicotine by means other than tobacco. It is used to help with quitting smoking or stopping chewing tobacco. It increases the chance of quitting smoking by about 50% to 70%. Often it is used along with other behavioral techniques. NRT has also been used to treat ulcerative colitis. Types of NRT include the adhesive patch, chewing gum, lozenges, nose spray, and inhaler. The use of more than one type of NRT at a time may increase effectiveness.
