Most people who smoke tobacco are law-abiding normal citizens who would like to stop. They would not resort to criminal or black-market activities if cigarettes were no longer legally available - they would just quit. Banning smoking would make this happen and massively lighten the burden on health resources of the countries in which it was banned. The reason why such actions may have happened in India was probably poor regulation of the market or mainly poor execution of already set out rules. Something that is easily preventable in Westernized countries.
