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.

New Zealand has only eight active novel coronavirus cases no COVID-19 patients in hospital after reporting another day of zero cases. However, the death toll rose to 22.

Zoom in: A top health official told a briefing a 96-year-old woman "was regarded to having recovered from COVID-19 at the time of her death, and COVID-19 is not recorded as the primary cause of her death on her death certificate." But health officials decided to include her death in the overall tally of deaths related to the virus.
