I heard that if you can die if you inhale a butane gas can through your mouth and your heart stop if hypeventilate before

I had a friend, well more of an acquaintance die a few months ago from trying to get high from huffing air duster. It was a long an painful death. He was at my friends house and my friend told me it was absolutely awful. He is currently seeking therapy from this. He said every time he closes his eyes he sees his friend laying there screaming with his muscles atrophying.
