While many of these restrictions are reasonable, the final restriction mentioned - the prohibition on electronic cigarette companies claiming that these products are safer than tobacco cigarettes - is both inappropriate and devastating to the public health interest.

Previous reviews have found that e-cigarettes are viewed by the general public as effective strategies for quitting and reducing harm, and research suggests some smokers use e-cigarettes for cessation purposes. Physicians may be interested in continuing the e-cigarette conversation with their patients in future appointments, as advising patients to quit smoking is the most often utilized intervention. The overall scope of most current studies show that, regardless of the delay from the FDA, most physicians will recommend e-cigs as a tobacco harm reduction tool, as they would any other traditional smoking cessation.

Whether e-cigarette use precedes smoking or smoking precedes e-cigarette use is a critical question, but it is one which needs to be answered through longitudinal research. We need studies that follow the trajectory of teen tobacco/e-cigarette use over time. That is the only way to determine which comes first.

Thus, the authors readily acknowledge that it is impossible from this study to determine whether or not e-cigarettes lead to smoking or whether smoking leads to e-cigarette experimentation.
