A US man has died after an electronic cigarette exploded in his face.
24-year-old William Brown from Fort Worth in Texas died on January 29th - two days after the device exploded in his car.
The Tarrant County Medical Examiner’s Office said the exploding device severed his left internal carotid artery.
His grandmother Alice Brown told the Fort Worth Star-Telegram that he was weeks away from his 25th birthday and had just bought the device before the accident.
“It just hurts so bad,” she said. “Now he’ll never see that birthday. It’s a waste of the things he could have accomplished.”
“It just all seems so unreal. He was running around doing his thing at 24 and now he’s gone.”
She said he was not a regular smoker - and had been told that there was a certain type of vape pen that could help with his asthma symptoms.
Mr Brown was at least the second person to die from an exploding vaporiser in the US over the past 12 months.
A report from the US Federal Emergency Management Agency said 133 people were injured by faulty devices between January 2009 and December 2016.
Last month a major new study published in the New England Journal of Medicine found that vaporisers are almost twice as effective as other nicotine replacements for giving up smoking.
