It has to do with denial. You're in denial about your own disease, and the sociopathy that controls UNKewlJ's lying.
You can't see that you merely substituted one mind altering substance for another when you stopped drinking? If you had at least stopped you could say, I was an alcoholic but I stopped because I saw where it was taking me. Instead, you denied your alcoholism because if you'd realized you were one you would have avoided all the other psychoactive drugs you've kept up with since.
