What difference does it make if it's a "disease" or just insanely dangerous?
You know what alcohol in your body has done to you. All the intellectual hair-splitting in the world doesn't change the scientific fact that alcohol is a highly addictive toxic chemical that takes over your brain and thus every aspect of your life. Once those neural pathways are engrained, they can reactivated at any time at the previous level of addiction.
Maybe one drink wouldn't reactivate them the first time. Maybe not even the second...but sooner or later you're going to be back on the hamster wheel from hell. It's like clog dancing on the freeway...you might not get hit the first five minutes, but you know you'll ultimately end up as a hood ornament in ugly shoes.
Please, please don't.
