If Delhi Government succeeds in ensuring that cigarettes are not sold within 100yards of educational institutions. If no smoking is enforced strictly in No smoking zones, then half the job is done. If one really understands the dynamics of tobacco and tobacco industry fully, vis a vis Indian politics and running of governments, very soon he realizes it's not so easy to make any place tobacco free. A practical way of approaching the issue,is to set attainable targets with respect to percentage of smokers among people, and achieve it. This way in the next four to eight years, the percentage of smokers will drastically come down. There can be no short-cuts if you look at it practically.
