Most of these products claim to help you quit smoking, but they have little to no scientific evidence supporting their effectiveness. Many of these products have been proven to be ineffective. They don't have to be harmful, they just have to work. You are free to do your own research, or just buy products that say they are safe and effective. I'm going to review the evidence for some of these products, so that you can make an informed decision. It's the most efficient way to stay away from dangerous products. These products come in a wide variety of packaging. Most contain little or no information about their benefits or risks. The biggest danger is nicotine. This can get you addicted to it, even if you don't smoke. If you are a smoker, I suggest you avoid any tobacco products containing nicotine. I think the best place to start is with e-cigarettes.
