What is a 'nicotine patch'?
A nicotine transdermal (meaning "going through the skin") patch delivers nicotine for a continuous level 24 hours a day. It takes about two hours to reach that effect, and then once you pull it off, it will take about 30 to 45 minutes for the nicotine levels to start diminishing. So we recommend that you put a patch on when you're ready to quit smoking. Because of this continuous level, there should be enough nicotine in that patch to satisfy the need in your brain for a cigarette, so that it basically extinguishes the withdrawal symptoms, makes someone feel OK. But it will never feel quite as good a cigarette, which gives a really high level with every puff that goes into the lungs and up the carotid arteries quickly to the brain. It will never feel like a cigarette, but it will keep you from having withdrawal.
