E-cigarette Vapors Contain Toxic Metals

According to a new study, E-cigarette vapors contain toxic metals.
Scientists at Johns Hopkins Bloomberg School of Public Health found that lead can leak from heating coils into the device's aerosols.
They tested for 15 metals in e-cigarette vapor.
They found high levels of chromium, manganese and nickel, but excluded arsenic, titanium, uranium and tungsten due to their low levels.
