TSNA levels in Canadian cigarettes
NNAL is the biomarker for one of the main tobacco-specific nitrosamines, which are predominantly formed during the curing and processing of tobacco, and through combustion that occurs when cigarettes are smoked. TSNA levels have a wide variation among different types of cigarettes depening upon the tobacco blend and curing process. For example, we have previously published a paper showing that Canadian cigarettes are much lower than US cigarettes on some TSNA levels. A new paper demonstrates that smokers in Canada actually ingest lower levels of one of the main TSNAs, consistent with some of our previous cross-country work. The public health issue is whether governments should limit TSNA. To date, however, it isn’t clear if the differences in TSNA levels translate into meaningful differences in risk: tobacco smoke has several thousand chemicals and dozens of different carcinogens. . The findings highlight the importance of additional research in the area of science to inform tobacco product regulation.

Tobacco industry science & destroyed documents
Over the past 20 years, tobacco companies have released more than 14 million “internal” documents through court disclosure requirements in various legal proceedings. Most documents span the period from the 1950’s through 2009, and represent a rich source of information on business practices, marketing strategy, and internal research and development activities.
We have reviewed tobacco documents in two areas. The first was a review published in the Lancet examining of industry research on smoking behaviour and the phenomenon of “compensation” for ostensibly “lower tar” cigarettes. Second paper examined Canadian documents that were intentionally destroyed to conceal evidence from the public.
