E-Cig Vapor Below USP Standards for Metals in Inhalation Medications


The study reported that: “The aerosol contained particles greater than 1 micrometer comprised of tin, silver, iron, nickel, aluminum, and silicate and nanoparticles (less than 100 nanometers) of tin, chromium and nickel. The concentrations of nine of eleven elements in EC aerosol were higher than or equal to the corresponding concentrations in conventional cigarette smoke. Many of the elements identified in EC aerosol are known to cause respiratory distress and disease.”

While the article scared many vapers by comparing the metal levels in e-cigarette vapor to that in cigarette smoke, it failed to inform readers that the levels of metals in electronic cigarettes are generally comparablle to those in nicotine inhalers. Today, I compare the levels of metals reported by Williams et al. to the USP standards for metals in inhalation medicines.
