AN eighth person has died from a mysterious lung disease as the across the US outbreak surges to 530 cases.
The growing toll has prompted officials to launch a criminal investigation.
However, they are still struggling to identify a single product or chemical in e-cigarettes behind the outbreak.
But Mitch Zeller, a director at the Food and Drug Administration, said: “The focus is on the supply chain.”
The illness was first reported in April and all patients are known to have used e-cigarettes — some containing the cannabinoid THC.
Symptoms can include fatigue, coughing, breathlessness and vomiting or diarrhoea. The 530 figure is up from the 380 sick reported a week ago.
The death toll is up by one, although an eighth unconfirmed fatality has been reported. Patients are mostly 18 to 34 and male.
States have begun banning e-cigarette sales and the first case has been reported in Canada.
Anne Schuchat, from the Center for Disease Control, urged vapers to give up. On the deaths, she said: “We do expect others.”
It came a day after India said it was banning e-cigarette sales and imports.
