I am definitely a believer in the addictive personality theory.
Certainly there are physical addictions to substances which are undeniable. But there are other forms of addiction that can be just as compelling, even though they are psychological. The one everyone knows about is compulsive gambling. (Compulsion and addiction are not identical, but they are certainly related. It is said that if you feel a compulsion to do something repeatedly, you are addicted to it.) A related addiction that I am struggling with in my own life, not in myself but in someone whom I love dearly, is computer addiction. Specifically, computer game addiction. It is just about to destroy our relationship.
Then, of course, there is compulsive overeating. Which, I am beginning to believe now that I have read and am trying the Carbohydrate Addict’s Diet, can be a physical as well as psychological problem, and I think I’ve experienced both aspects of it.
I don’t know about “disease” vs. “weak mind”, I think that is too simplistic. But even if you could say that people who suffer from addictions have “weak minds” that doesn’t make them bad, it makes them weak, and what they need is tools to build up their strength.
This is a non-smoking area. If we see you smoking, we will assume you are on fire and act accordingly.
