I spent a lot of time working in India a few years ago, 26 weeks, spread over 2 years.
The governments over the last 5 years, or so have been doing their best to discourage any form of smoking.
Cigarettes, hookah pipes, and vapers.
There was a resurgence of the use of hookah pipes a few years ago, that was quickly put down by propaganda informing people they were more dangerous than cigarettes.
The same is now happening with vaping.
Basicaly the government does not want to see anything new starting up.
Not for any health, or financial reason, simply that if they have a population of smokers they prefer them to use traditional cigarettes.
