Although there are probably a few minor similarities in the behaviors of alcoholics and addicts, I would not be inclined to say all are of the 'addictive type". I would say "short attention span" would be more like it. But, not everyone with a proclivity to this type of behavior will become an aloholic or addict. And, not every alkie or addict exhibits this behavior. You really have to look for the similarities between alkies and addicts. They aren't usually very obvious.
Oh, and never say never about become an addict or alkie. It can happen at any age if you've got the right body for the disease to live in.
Re, drug therapy. I know of no current studies or attempts to create a drug that make an alcoholic or addict able to drink and use. There still disagreement over the concept of "disease" for anyone to get much past that.
