An addictive personality is often talked about, but I'm not entirely sure that it exists. Yes it is true that some people get addicted to more than one thing, or that when they stop abusing one substance they get hooked on something else. but that doesnt necessarily mean that they have an "addictive personality". I think it is more likely that when they quit the substance, they have not learned new coping strategy to deal with their problems/stress, so they resort to the same old methods they have always relied on. they think they have mad progress because they have given up eg booze, but might become a workaholic, or start abusing another substance etc.
