I've heard about this and it really upsets me. During the height of my drinking I would have used this to justify more drinking, "Oh I don't drink hand sanitizer/mouthwash/perfume so I'm not an alcoholic" as that was my pattern. It's sad really.
There was an episode of Intervention where this guy was only about 22 years old and was an alcoholic. He had been hospitalised something like 12 times in 3 months from alcohol poisoning and he got out of the hospital bed and started drinking the hand sanitiser. It was so upsetting.
