Nearly a quarter of those trying to conceive said they regularly or occasionally vaped, according to the report by the women’s health firm Hertility based on data from 325,000 women, mostly in their 20s and 30s. The study was conducted in the UK and was based on analysis of anonymised data.
Are we back to the time of not knowing second hand smoke introduces a lot of the same health risks as first hand smoke? Anyone would be able to infer that women that want to get pregnant shouldn't smoke from the proposed headline, but they might think a bit more about their own contributions to the health of others.
Because its the responsibility of adults to make healthy choices for themselves? Vape companies aren't going to peoples houses and pumping vapor into peoples houses while they sleep.
