Résumé / Abstract
Smoking remains the leading cause of preventable
disease in the United States. Exposure to tobacco smoke leads to cancer,
heart and lung disease, and addiction. The origin of the tobacco and
cigarette manufacturing practices of counterfeit cigarettes are unknown.
Because toxic metals are incorporated into the tobacco lamina during
cultivation, the ambient metal content of the soil could produce
significant differences in metal levels in both the tobacco and smoke of
counterfeit cigarettes. We compared mainstream smoke cadmium, thallium,
and lead deliveries from counterfeit and authentic brands. Mainstream
smoke levels of all three metals were far greater for counterfeit than the
authentic brands, in some cases by an order of magnitude. Significant
differences still existed even after normalizing mainstream smoke metal
levels with nicotine delivery; the counterfeits typically delivered much
higher levels of all three analytes. Our findings, based on 21 different
counterfeit samples, suggest that counterfeit cigarettes potentially
result in a markedly greater exposure to toxic heavy metals than authentic
brands, even after correcting for differences in nicotine intake. In view
of the unknown health risks associated with inhaling higher levels of
toxic metals, it is prudent to minimize exposure to toxic substances
whenever possible. Published by Elsevier Ltd.
