Nicotine
"My mother smoked for over 50 years and was recently in hospital for pneumonia. She had to be put on the patch (21 mg) while in there. I am thrilled to say that it has been 16 days and she has not even thought about a cigarette. I say that is a miracle because she always had to have an extra pack of cigarettes so she would not run out! Thank you for a great product!"
