Late last month, the University of Michigan released the results of the 2013 , a national study of youths in grades 8, 10, and 12. Despite the CDC's sirens about how e-cigarettes are leading to an increase in youth smoking, the data show that youth smoking rates reached a record low in 2013.

In the above analyses, the authors controlled for level of nicotine dependence.

Today, I express my opinion that the use of these studies to draw conclusions about the efficacy of e-cigarettes for smoking cessation is not just unscientific, but dishonest as well.
