How much is vaping taking up the slack? Here in the UK it seems that cigarettes have to be hidden from view in a 'drawer of shame' while vapes are in left clear view. I'm not sure why vapes seem to be getting an easier ride than cigarettes. Are vapes any less harmful than cigarettes? Apart from the effects on health they create a lot more waste. Also some vapes seem to be clearly marketed to children. (Disclaimer: I have never smoked or vaped, so it isn't a subject I know much about. Please enlighten me.)
