The reason people get addicted is because, as a non-addict, they have no conception of how powerful and addiction actually is. They figure they won’t get addicted because they’re not stupid, or what not.
E.g., Many folks said “I’ll just quit smoking when I get out of high school.” For the addict chance is low. There is currently no way to determine, in advance, the degree of someone’s addictive nature.
Addiction is a pyschosomatic experience. Non-addicts can’t comprehend addiction anymore than someone who has been blind from birth can comprehend color.
Actually it’s not psychosomatic.
Addicts’ body and brain chemistry has been altered by the drug they abuse. It takes control of them and there’s tons of research on the effects of addiction on the brain.
Psychosomatic would refer to a perceived illness with no basis in biology.
