Now in the US if a passenger lights up during a flight, the purser may sue the manufacturer for "health problems" caused by passive smoking. The ruling, passed by a Miami judge, has triggered off a fracas between the anti-smoking lobby and tobacco firms. The Miami suit tests whether tobacco companies can be held liable for health consequences of "second-hand smoke". The action was enforced in 1991 by 25 former non-smoking flight attendants against Philip Morris, and 7 other cigarettemakers.
