Carcinogenicity of N'-Nitrosonornicotine in Sprague--Dawley rats

Journal Article · · Ann. Surg.; (United States)
OSTI ID:7256404

N'-Nitrosonornicotine was added to the drinking water of outbred Sprague-Dawley rats. Adenocarcinomas of the olfactory epithelium occurred in all 15 rats, squamous papillomas of the esophagus in 1, squamous papillomas of the nonglandular stomach in 1, and a hepatocellular tumor in 1. The possible ingestion and subsequent in vivo nitrosation of nicotine and/or nornicotine could create a serious carcinogenic hazard to cigarette smokers.
