Progression to traditional cigarette smoking after electronic cigarette use among US adolescents and young adults
This study set out to work out what effect trying vaping had on 16 to 26 year-old non-smokers who weren’t susceptible to smoking.
They asked about vaping at the start of the study, and then followed up a year later to see if participants had smoked or become susceptible. Almost 700 participants were included in the study.
What They Found
Of the 16 participants who had vaped at the start of the study, 11 of them progressed “towards” cigarette smoking a year later. Six actually smoked and the remaining five just became susceptible. This was a larger percentage than those who didn’t try vaping.
The authors concluded that “use of e-cigarettes at baseline was associated with progression to traditional cigarette smoking,” and it spawned headlines such as “E-cigarette smoking gateway to the real thing, study finds.”
What’s Wrong With It?
Although this study determined whether the vaping or smoking came first, there’s still a familiar problem. Both vaping and smoking were defined as any use, even just a puff.
Taking a puff of an e-cig then later taking a puff of a cigarette is not a “gateway effect” in the way anybody understands it.
The tiny sample of 16 for the “e-cig user” group just heaps problems onto the already flawed study, and only six of them went onto smoke.
