Smokers are being warned about the increased fire as well as health risks of buying cheap illicit cigarettes.
Derbyshire County Council has issued the warning after illicit tobacco products seized in recent raids were missing vital safety features which help to prevent house fires.
Deputy cabinet member for health and communities Councillor Ellie Wilcox said: “The fire risks of fake tobacco are all the more reason for people not to smoke. But if they choose to do so they should buy tobacco from a legitimate local shop.
“It’s no surprise that criminals involved in the illegal tobacco trade are prepared to risk even more lives by flouting safety laws designed to protect people from house fires.”
