It may be an artifact of the division between body and mind, common in Western cultures. Any problem related to the psyche is treated differently (ie taken less seriously) from problems related to the body. I wonder how many millenia this ostensibly subtle difference in conception will keep on giving us pain and mental anguish. Its so deeprooted, I wonder what it will take to pull it out.
There are plenty of people hooked on this stuff in the east. Addiction doesn't care about your philosophy. Some people are just more mentally available to addiction in all it's myriad forms.
