Dozens of people say they have been fired, bullied and discriminated against due to their vaping habit, according to a study by an e-cigarette firm.

After speaking to about 2,000 vapers, online retailer E-Cigarette Direct said that one in five experienced negative reactions from colleagues due to their vaping, with 44 reporting bullying and 13 saying they were fired.

James Dunworth, chairman of the firm, said: "It is quite shocking to learn people have actually lost their jobs due to vaping." He expressed concern over individuals' "health and happiness" in the workplace, adding: "We spend at least a third of our waking lives at work."
