Lessons from the history of tobacco harm reduction: The National Cancer Institute's Smoking and Health Program and the "less hazardous cigarette".
Scientists and public health practitioners are sharply divided today over the risks and benefits of tobacco harm-reduction strategies. At the same time, a range of novel tobacco products is being marketed with claims of reduced exposure or risk. Current scientific efforts to study tobacco products and harm reduction should be informed by past experience. ⋯ NCI officials predicted during the mid-1970s that new "low-tar" cigarette brands would substantially reduce smoking-related mortality, but by 1978 the research agenda began to change in response to a reorganization of NCI research activities, modification of government antismoking efforts, and an emerging understanding of nicotine addiction that challenged key scientific assumptions. In retrospect, the program suffered from significant weaknesses that severely limited the likelihood that it would generate knowledge beneficial to public health, including a research agenda that failed to include surveillance and behavioral research, tobacco industry influence of the research agenda, and a lack of access to information about the characteristics of products on the market. There exists today a need for a public health-oriented research agenda on tobacco products and harm reduction, but current efforts should include input from a diverse range of disciplines, collect data on users' behavior, and limit the involvement of industry scientists.
