A New York University study has identified a pattern of lung cancer in mice exposed to the same amount of e-cigarette vapor as someone who's been using e-cigs for approximately three to six years.

The big picture: As vaping deaths and illnesses rise, the medical community and health regulators are increasingly concerned about the unknown effects of e-cigarette use. While e-cigs were originally meant to help cigarette users ween off smoking as a whole, vaping has dramatically increased in popularity in recent years, especially among young people.

By the numbers: The study exposed 40 mice to vapes with nicotine for 54 weeks. Out of that population:

  • 22.5% developed lung cancer
  • 57.5% developed pre-cancerous lesions in their bladders
  • Meanwhile, 20 separate mice who were exposed to vapes without nicotine were cancer free

What they're saying:

"E-cigarette vaping can cause lung cancer and pre-cancer changes in bladder in mice. The carcinogenic mechanism is via production of nitrosamines, the proven human carcinogens. So, the probability that e-cigarette vapor is a human carcinogen is high."
— Moon-Shong Tang, the study's lead professor, told Axios.

In response, federal, state and local lawmakers have been increasingly pushing for bans on the sale of e-cigs in general and flavored vape products in particular, due to their popularity among young people.

64 people have died from a lung injury associated with e-cigarette use in 28 states and the District of Columbia, the Centers for Disease Control and Prevention reports as of Feb. 4.

What's new: Nationally, most vaping-related patients with data on how they sourced products reported obtaining THC-containing products from "informal sources," per the CDC. The agency recommends users should consider no longer vaping THC products, rather than its original claim to refrain from e-cigarettes.

The delay in implementing comprehensive regulations for e-cigarettes has contributed to a growing crisis of vaping-related illnesses and deaths across the U.S. and poses particular risks to young adults.

The big picture: E-cigarette use by American teenagers has surged, and the dangers are heightened by unsafe black market vaping devices and THC cartridges. But a recent flurry of regulatory activity by states looks set to continue, with federal action following shortly.
