Vaping exposes users to around 2,000 chemicals, including potentially harmful industrial compounds, according to a study of four popular brands by researchers at Johns Hopkins University.

Most of the chemicals found were unidentified, but of those that were, six were cause for concern, according to the study published in Chemical Research in Toxicology, a peer-reviewed journal. Researchers found condensed hydrocarbon-like compounds that are typically associated with traditional combustion products like cigarettes, despite the fact that vaping is often marketed as safer than those products. The study also found caffeine in some, which isn’t disclosed on labels.
