4. People smoke because they are addicted to nicotine, but nicotine itself is not especially hazardous; it is the other constituents of tobacco smoke that cause most of the harm . Use of smoke-free nicotine would benefit smokers directly by reducing the personal harm caused by nicotine addiction. What is harm reduction, and how would it work for smoking? Excerpts from: Ending tobacco smoking in Britain; Radical strategies for prevention and harm reduction in nicotine addiction, Royal College of Physicians of London, 2008.

14. Among Swedish male daily smokers who take up snus use… 55% end up as daily users of snus only 32% end up as free of any daily tobacco use 3% end up as continuing daily smokers 10% end up as dual daily users These figures demonstrate that… - Only a small proportion develops dual use. - A substantial proportion eventually escapes nicotine dependence. The idea that snus use were strengthening dependence is not consistent with these findings.
18. Smokers who have started subsequent snus use appear to make more efforts to quit smoking than those who have not.
