Alternative nicotine delivery systems (ANDS)--public health-aspects.

This paper deals with a relatively new category of pharmaceuticals, namely alternative nicotine delivery systems (ANDS). We do not refer to products like smokeless tobacco or other smoking devices. ANDS are designed to provide nicotine without the harmful substances contained in cigarette smoke. Several different nicotine replacement preparations exist, which are used in nicotine replacement therapy to obtain tobacco abstinence. There is a bulk of scientific literature on the clinical use of ANDS, but very little has been published on the public health aspects of the same. Nicotine dependence is associated with heavy consumption, tolerance, regulation of intake and withdrawal. We described a new symptom of extreme nicotine dependence, namely the nocturnal sleep disturbing nicotine craving (NSDNC), and developed a concept of a nicotine pre-abstinence syndrome (NPAS). Five nicotine replacement preparations are currently available: gum, patch, nasal spray, oral inhaler and sublingual tablet. As far as safety issues are concerned, scientific evidence shows that the use of ANDS involves almost no risk for consumers and patients, especially when compared with the consumption of tobacco products. New concepts developed by our group are the following: definition of possible endpoints of smoking control measures, reduced smoking, nicotine dependence and preventive oncology, chemoprevention of lung cancer by ANDS, public health impact by OTC availability of ANDS and the "let them choose approach" of ANDS focusing on the specific preferences and needs of the individual client. One may also speculate whether ANDS will, at some stage, replace cigarettes as the major source of nicotine for people who need this psychoactive drug.
