After urging FDA to ban e-cigs in 2010 because (he claimed) e-cigs don't emit nicotine, FDA funded Tom Eissenberg's new study urges policy makers to consider imposing nicotine limits on vapor products (after his study found that vapers using 36mg/ml nicotine e-liquid could consume even more nicotine than smoking a cigarette.
Electronic cigarette nicotine delivery can exceed that of combustible cigarettes: a preliminary report -- Ramôa et al. -- Tobacco Control
The only thing consistent about Eissenberg is that he is quick to recommend nationwide e-cig policy changes based upon findings of just one small study, and in this case, his findings and policy recommendations totally contradict his claims from just five years ago.
Below is his policy recommendation (from the full text version of the study)
"Thus, some ECIGs appear capable of exceeding the nicotine delivery profile of a combustible tobacco cigarette. We speculate that this excessive nicotine delivery may be harmful if it leads to a greater level of nicotine dependence, which could make ECIG cessation difficult if users eventually choose to try to quit their ECIG use. Alternatively, users of higher nicotine liquid concentration may control nicotine intake by altering their puffing behaviour. Nonetheless, there is no clear rationale for a product that potentially delivers more nicotine than a tobacco cigarette, thus policymakers worldwide may want to consider limiting access to ECIG device/liquid combinations that demonstrate this nicotine delivery profile."
