"I am constantly surprised by the prejudice I find in some against vaping – the unthinking bias and the fact-twisting. It’s taking millions of people out of a lethal habit, it’s saving lives, and in social situations it produces only the smell many already have pumping from numerous kinds of scent makers and air fresheners in their homes."
