Lots of chatter in the comments about a new study, one of whose authors is Our Stan (aka Stantonitis Glands), claiming that there had been a sharp fall in the number of children admitted to hospital with severe asthma after the smoking ban was introduced in England. Both DP and Chris Snowdon are on the case.
The implication is that this is the result of reduced secondhand smoke exposure. Of course, the smoking ban mainly affected places where children don’t go, ie. workplaces, pubs and clubs, so the authors suggest that the smoking ban inspired people to make their own homes “smokefree” of their own volition.
