When non-smokers breathe in this smoke, they are exposed to harmful chemicals that can damage their cells and increase their risk of developing cancer
This pairing yielded the third-highest score, demonstrating that the sum was greater than the two parts
Five specifications of increasing complexity were compared (main effects, two-way interactions with year, additional cross two-way interactions, selected three-way interactions, and a full four-way model including lower-order terms) using Bayesian generalised linear models fitted with INLA [10]
While it is reasonable to assume that, if existing smokers switched completely from conventional cigarettes (with no other changes in use patterns) to e-cigarettes, there would be a lower disease burden caused by nicotine addiction, the evidence available at this time, although limited, points to high levels of dual use of e-cigarettes with conventional cigarettes, no proven cessation benefits, and rapidly increasing youth initiation with e-cigarettes, the authors said
