Some people say to buy only nicotine patches because that's the only ones with any nicotine in it. Well, this is a completely wrong thing to do. Nicotine patches are not a cure for smoking. Nicotine patches have many side effects, such as increased risk of cardiovascular disease, diabetes, and lung cancer, among many others. Also, some people start taking too many patches, which can have fatal consequences. Nicotine patches contain only a small amount of nicotine, so the risk of taking more than you need can be severe. The best products are the ones that don't contain any nicotine. You can easily avoid all the side effects by buying a nicotine patch that doesn't contain nicotine. This is an important point to keep in mind. There are several brands of nicotine patches available in the market. Most of them are available in multiple different strengths. It is very important to know the difference between them, and which one will work best for you. You can easily determine the strengths by reading the label. Some patches have only one strength. Others contain many different strengths, and others don't even have one. It all depends on the brand of the patch.
