The Center for Environmental Health (CEH), citing an in-house report showing most of 97 e-cigarettes tested produced high levels of cancer-causing chemicals, said it would file suit against their manufacturers.

CEH described its report as the first large sampling of e-cigarettes and vaping products, including brands made by major cigarette companies. Ninety per cent of the 24 companies whose products were tested were marketing at least one that produced levels of formaldehyde and acetaldehyde higher than allowed in California, CEH said.
Founded in 1996 to protect people from toxic chemicals, CEH said it would take action in California against offending companies for failing to warn consumers under a law known as Proposition 65. Earlier this year CEH took action against vaping companies for failing to warn consumers about nicotine risks. “Anyone who thinks that vaping is harmless needs to know that our testing unequivocally shows that it’s not safe to vape,” said Michael Green, CEH executive director.
