Dear Sir,Great effort has been taken by the team of Raute[1] in air quality measurements at various venues to assess second hand smoke exposure. They wanted to assess the implementation of smoke-free policies, seven months after enforcement of the law mandating a ban on smoking in public places. They found 32 out of 50 venues where smoking within premises was not observed, which they consider as less. In India, 64% compliance within 7 months of implementation of a law is really a good number, I feel.Moreover, the authors have concluded that considerable scope for improvement in implementation of smoke-free policies exists. This statement would have had greater emphasis if they would have found out lacunae in implementation of the law. For example, they could have interviewed the owner and workers at the venues they assessed, which in turn would have revealed issues like their knowledge about the law, attitude towards it, knowledge about the hazards of smoke, etc., Through these efforts, they could have managed to find out ways to improve the implementation of the law, rather than just mentioning that there was scope for improvement. Nevertheless, the initiative which they took should provoke the policy makers, administrators and researchers to tackle this important issue of second hand smoke which is a preventable public health hazard.
