“Our findings suggest that e-cigarettes release unstable chemical mixtures containing a large variety of chemical products with unexpected toxicological properties. Regulators need to be made aware that these compounds can form so that toxicology studies can be initiated to evaluate their...
A list of smoke toxicants and their approximate concentrations in today's cigarettes is nearly useless without an appropriate ranking of their relative toxicity. Unfortunately, the toxicological data for ranking importance are available for fewer than 5% of the approximately 4800 reported smoke ...
