The team falsely claim: “Since 2017, the number of studies reporting on the association between e- cigarette use and smoking behavior has continued to accumulate.”
They say they, “conducted 4 analyses, examining (1) the effect of e-cigarette consumer product use among people who smoke, regardless of motivation to quit smoking; (2) the effect of e-cigarette consumer product use among people who smoke who are motivated to quit smoking; (3) the effect of daily and less-than-daily e-cigarette consumer product use among people who smoke; and (4) the effect of being provided with free e-cigarettes as a therapeutic intervention in RCTs compared with conventional therapy.”
Thanks to selective inclusion of some studies and ignoring others, they erroneously conclude:
- E-cigarette companies and e-cigarette advocates have promoted e-cigarettes as effective cigarette smoking cessation tools. In this meta-analysis, we found that, in observational studies of adults who smoke cigarettes, e-cigarette consumer product use was not significantly associated with cigarette smoking cessation.
- In observational studies of adults who smoke cigarettes and express some motivation to quit smoking, e- cigarette consumer product use was not significantly associated with cigarette smoking cessation.
Wang said: “In observational studies, you’re basically asking people ‘out in the wild’ about their use of e-cigarettes that they’ve purchased themselves from a corner store, without specific guidance to quit. But in a randomised trial you’re testing a product, treating it like a therapy – a medicine – to see if an e-cigarette or some other product is more conducive to quitting.”
“It’s important to recognise that in clinical trials, when certain e-cigarette devices are treated more like medicine, there may actually be an effect on quitting smoking. But that needs to be balanced against the risks of using these devices. Also, only seven e-cigarette devices were studied in the clinical trials. Whether the effect observed with these seven devices is the same or different than that of the thousands of different e-cigarette products available for sale is unknown.”
Wang added: “The question we explored is of both scientific interest and public health interest, and we hope that the [Food and Drug Administration] will pay attention to our study as they try to make these decisions.”
The Planet of the Vapes forum has around 60K members who, almost exclusively, have used vaping to quit tobacco use. We sincerely hope nobody pays attention to this piece of junk masquerading as a study.
