The Stratford Fire Department is issuing a warning to people who vape or use e-cigarettes.
The warning comes after an e-cigarette exploded in one man's mouth, knocking out two of his teeth and cracking two others a few weeks ago.
"Right in his mouth," says Lt. Robert Daniel. "Some of the witnesses stated it sounded like an M-80 going off."
Newer e-cigarettes are called "regulated mods" and include short-circuit protection, something the victim's setup did not have.
Fire officials say that victim is doing OK.
Workers at smoke shops say they want to stress that vaping is perfectly safe if done correctly.
They say regulated mods are more expensive, but they can prevent an explosion like the one that occurred in Stratford.
