NO NO NO NO.......
Robin Williams's death had ZERO to do with drugs.
He had Lewy Body Dementia, which was gradually robbing him of his ability to function, and as a physical comic and one of the funniest people on the planet, he could not live like that. I wouldn't want that, that's for sure... and rather than be in that prison of the body, he decided he couldn't take it anymore. It's just when you have a family it's just 1,000,000 times worse and something I don't understand but that's what those kind of degenerative diseases do...
