Anecdotal but, a business we buy supplies from that hires all mentally handicapped people, they had CV run through their office last year, 2 people died (they were apparently very unhealthy from what I have been told), everyone that works there got it except for 2 men - both smokers. The guy that delivers to us is one of the smokers that didn't get it.

So when I read that 4chan post a couple days ago about the same and nicotine it made a lot of sense.
