Nicotine is a highly addictive compound found in all tobacco. It is conceivable that some cigarette companies might put extra nicotine into their brands to ‘hook’ users.
The pharmaceutical industry has produced nicotine products in the form of patches and chewing gum in an attempt to remove the need for people to obtain nicotine from smoking.
This is simply transferring the addiction from one method of administration to another. However, it is probably better to use a nicotine patch or chewing gum rather than smoking because you will be protecting the lungs, but dependence on these products maintains the addictive aspect and is less likely, therefore, to reduce the smoking craving in the long term. Many people are allergic to the patches and struggle with nausea when nicotine is chewed. See Smoking.
