This lower has been noticed in parallel to the elevated quantity of people that have tried vaping as a smoking cessation technique, which rose from 3.7% to 9.7% over the identical interval.

The variety of people who smoke who tried to give up utilizing medicine and cessation companies decreased from 14.6% to 11.1% and from 7.5% to five% respectively.

Nevertheless, the authors notice that these information come from the US, and that merchandise on the US market could differ from these bought in Europe
