Study: Vaping Nicotine Causes Cancer

A study sponsored by National Institutes of Health showed that E-cigarette vapor causes lung cancer and potentially bladder cancer in mice, damaging their DNA and leading researchers at New York University to conclude that vaping is likely “very harmful” to humans as well. The amount of smoke the mice were exposed to was similar to what a human would inhale if they vaped regularly for about three to six years.

“It’s foreseeable that if you smoke e-cigarettes, all kinds of disease comes out” over time, Moon-Shong Tang, the study’s lead researcher, said in an interview. “Long term, some cancer will come out, probably. E-cigarettes are bad news.”

As e-cigarettes or vaping products are still fairly new, only time will tell as to how carcinogenic vaping nicotine actually is, yet the study is the first to link vaping nicotine to cancer.

Researchers at NYU also found that e-cigarette vapor caused DNA damage in the lungs and bladder and “inhibits DNA repair in lung tissues.” Out of 40 mice exposed to e-cigarette vapor with nicotine over 54 weeks, 22.5% developed lung cancer and 57.5% developed precancerous lesions on the bladder.

None of the 20 mice exposed to e-cigarette smoke without nicotine developed cancer over the four years they studied the mice, researchers said.

That’s “statistically very significant,” said Tang, who’s a professor at the NYU School of Medicine.

A study released in February by the University of Southern California, found that e-cigarettes cause the same molecular changes in oral tissue found in smokers or regular cigarettes.

As of October 8, 2019, 1,299* the outbreak of lung injury cases associated with the use of e-cigarette, or vaping, products have been reported to CDC from 49 states, the District of Columbia and 1 US territory.

Twenty-six deaths have been confirmed in 21 states. Alabama, California (3), Connecticut, Delaware, Florida, Georgia (2), Illinois, Indiana, Kansas (2), Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New York, Oregon (2), Pennsylvania, Texas, and Virginia. More deaths are under investigation

The median age of deceased patients was 49 years and ranged from 17-75 years.

Among 1,043 patients with data on age and sex:

70% of patients are male.

The median age of patients is 24 years and ranges from 13 to 75 years.

80% of patients are under 35 years old.

By age group category: 15% of patients are under 18 years old; 21% of patients are 18 to 20 years old; 18% of patients are 21 to 24 years old; 26% of patients are 25 to 34 years old; and 20% of patients are 35 years or older.

The latest findings from the investigation into lung injuries associated with e-cigarette use, or vaping, suggest products containing THC play a role in the outbreak.

All patients have a reported history of e-cigarette product use, or vaping, and no consistent evidence of an infectious cause has been discovered. Therefore, the suspected cause is a chemical exposure.

The specific chemical exposure(s) causing lung injuries associated with e-cigarette product use, or vaping, remains unknown at this time.

No single product or substance has been linked to all lung injury cases. More information is needed to know whether a single product, substance, brand, or method of use is responsible for the outbreak.

Among 573 patients with information on substances used in e-cigarette, or vaping, products in the 3 months prior to symptom onset:

About 76% reported using THC-containing products; 32% reported exclusive use of THC-containing products.

About 58% reported using nicotine-containing products; 13% reported exclusive use of nicotine-containing products.

This complex investigation spans many states, involves hundreds of patients, and involves a wide variety of substances and e-cigarette, or vaping, products.

If you or anyone you know is experiencing symptoms associated with e-cigarettes and vaping, and has used these products in the past 90 days; it is important that you immediately speak to a healthcare provider.
