As someone who's been broke as fuck and addicted to smoking at the same time while not having the capacity to quit there was no way I was not having cigarettes. I never robbed anyone but I can see how you'd get there and I did buy tobacco on the black market (smuggled in and sold illegally not stolen) when I could. It's harder to quit when you're under the poverty line and pushing people by making it more expensive is going to have negative consequences like an increase in crime!
