HONOLULU (HawaiiNewsNow) - University of Hawaii Cancer Center researcher Pallav Pokhrel said two ingredients manufacturers mix in E-cigarette liquids are of particular concern.
"They usually like to mix propylene glycol and vegetable glycerin." he said.
When propylene glycol and glycerin are vaporized they produce formaldehyde. a gas that's used in embalming fluid and building materials. Formaldehyde is a known human carcinogen.
"It seems like it becomes dangerous when the E-liquid is heated at a high temperature, with high voltage, and when the E-liquid is dripped directly to the heating coil," he said.
