Smoking
Nicotine Addiction

Thanks in part to restaurant and bar bans, taxes on cigarettes, and better public health programs, smoking has decreased in the developing world. By 1997, Americans were smoking at half the rate that they were in the mid-1960s. But for those who relish the social rituals of smoking and the temporary rush of that nicotine high, disincentives to smoking may not convince them to kick the habit.
