Is drug addiction really a disease?

First of all, I'm a guy, and it says that on my profile, so there's something you're wrong about. Second of all, if my information is so commonly wrong, then provide some proof. Third of all, just because you have a drug addiction doesn't make you the foremost expert on drug addictions, diseases, or disorders. Lastly, it's been in debate for years now as to whether it's a disease or a disorder, and there is no fine line that states which it is. I simply stated my opinion on the matter, and although I admit I could have been more clear on that being my opinion, fact is that there are people who argue for both sides of this, so neither of us are wrong in this case.
