There is a wide range of efforts on cigarette harm reduction. This is done mostly in the shape of educating people about the harms of cigarettes, and products aimed at curbing the craving of nicotine without the added harmful chemicals.
Products aiming to relieve the nicotine craving, including nicotine patches, chewing gum and mouth sprays, but that have little or no other harmful chemicals, have existed for decades. This, along with the more recent efforts in the form of electronic cigarettes have been the key harm reduction tools for tobacco smokers. Electronic cigarettes have proved to be effective, in that they provide the user with the similar experience (in the shape, route of administration), they contain nicotine but not other chemicals that are usually found in a cigarette.
