If this was true (which I'm 99.99% positive it's not), that would be like absorbing 660 mg of nicotine a day for 9 months. Assuming he was actually sleeping 8 hours a night and using his e-cigarette non-stop the other 16 hours, he would have had to have been vaping about 17 ml (approximately 12 typical pre-filled cartridges) of 24 mg nicotine per hour to get that much nicotine in his system! Nicotine stays in the human body 24-48 hours and experts say the potential lethal dose of nicotine for a 150 lb human is 30 - 60 mg. I'm not even sure if it's physically possible to vape that much in 60 minutes. Typical e-cigarette users, even previously very heavy smokers, report they use only 3 - 6 ml per day.
Dude, you would have been dead the first day if you vaped that much. Unless you were drinking the liquid straight from the cartridges. If that's the case, you weren't doing it right. And the "anti freeze" lie that people keep spreading around is getting old. If you prefer smoking, just say so. But please don't tell lies about a device that is saving millions of lives.
