People drink anything.
There are areas where I live that have epidemic levels of alcoholism and the stores had shelves full of cans of Lysol. People poked holes in the can and poured the liquid out, mixed it with water, and drank it. Cheap, accessible, could buy it at any hour any day.
It is very dangerous and I'm not sure if it is still a problem or not but I'd be surprised if it wasn't.
