Tobacco Harm Reduction Expert Fact Checks UCSF “Gateway” study

Dr. Brad Rodu

Dr. Brad Rodu, a renowned Professor of Medicine at the University of Louisville who holds an endowed chair in tobacco harm reduction research, has called for the retraction of a Pediatrics article by University of California San Francisco’s Benjamin W. Chaffee, Shannon Lea Watkins, and Stanton A. Glantz.

The article claims that “Among adolescent cigarette experimenters, using e-cigarettes was positively and independently associated with progression to current established smoking.”

“The findings and the claim are false,” wrote Dr. Rodu. “In their analysis, the authors ignore the fact that their study group consisted entirely of experimental smokers with widely varied experience….”

“When we added lifetime cigarette consumption (LCC),” Dr. Rodu explained, “the positive results for e-cigarettes essentially disappeared, negating Chaffee’s core claim.”

“Their study should be retracted.”
