Smaller diameter cigarettes show lower alleged mouse skin tumorigenicity

{{#badges: Tobaccowiki}} Smaller diameter cigarettes show lower alleged mouse skin tumorigenicity

This 1976 internal R.J. Reynolds memo from Frank Gerhardt Colby to Murray Senkus discusses unpublished research sponsored by the Tobacco Research Council of the United Kingdom of Great Britain which showed that decreasing the diameter of a cigarette (circumference) reduced to tumorigenicity of the cigarette. The memo attributes this largely to the higher flow rate of the puff through the smaller-diameter cigarette.
