I'm the same way. Try to keep it uncommon. I hadn't really thought about it that way but it's true. I guess that's an example of Maslow's hierarchy of needs in action. For someone who isn't in that position of poverty, they think about how that behavior affects their health and social status, but in order to have any sort of focus on those issues of safety and self-actualization, you first have to be content in your psychological state. Many aspects of poverty are detrimental to that psychological state, so cigarettes and beer help with that at the expense of goals that are more far removed, and seem less urgent to people in positions of poverty.
