Can someone still develop the habit of gambling and become an addict even though no one around gambles?
Humans are social being, if others in the society are not around gambling then I think gambling addiction will not survive for long. And gambling comes from thousands of years ago, so I think some changes may come as a result of the change in environment, but it will not be possible to turn gambling off.

But if someone starts it and gives the idea that it's fun and there's money on it, the likely of influencing the others is very high. That's what is going to happen.
At first, if there's no encouragement, there will be no people that shall gamble at that place. And if somebody gets the initiative then we can't be sure if it won't exist there.
