Based on the information provided, the document appears to be a report from the National Cancer Institute Expert Committee on the Carbon Monoxide Yields of U.S. Cigarettes. The report is part of the Smoking and Tobacco Control Monograph No. 7, published by the Department of health and human Services, National Institutes of health, National Cancer Institute.
The report mentions several studies and sources, including "The FTC Cigarette Test Method for Determining Tar, Nicotine, and Carbon Monoxide Yields of U.S. Cigarettes," a toxicity testing plan by the US Consumer Products Safety Commission and the US Department of health and human Services, and several research articles on cigarette smoke and its components, such as tar, carbon monoxide, hydrogen cyanide, and acrolein.
The findings of the report suggest that while tar yields of cigarettes have been used as a surrogate measure for the harm caused by cigarette smoking, they may not be a reliable predictor of exposure to other harmful components of cigarette smoke, such as carbon monoxide, hydrogen cyanide, and acrolein. The report highlights the need for more comprehensive testing and regulation of cigarettes to accurately reflect the health risks associated with smoking.
In summary, the report emphasizes the limitations of using tar yields as a sole measure of cigarette harm and recommends a more holistic approach to regulating and understanding the health risks associated with cigarette smoke.
