Fair enough - there's strong evidence that passive smoking increases the risk of heart attack, lung cancer and cot death. Now some smoking researchers are warning that third-hand smoke - the particles that linger on skin and clothes long after the cigarette has been extinguished - could also be a danger (see "Fuming"). Is this a step too far?
