The study, which appears online Jan. 4, 2020, in Tobacco Regulatory Science, found that nicotine concentrations were five to eight times higher in rodents that were exposed to JUUL versus other tobacco products. The work also supports an earlier finding by the same researchers of harm to blood vessels from brief exposures to both direct and secondhand smoke from cigarettes, little cigars and combustible marijuana, and to aerosol from IQOS “heat-not-burn” tobacco products.
JUUL and earlier generation e-cigs are promoted as being less hazardous than cigarettes. Since 2016, there has been a dramatic increase in youth e-cig use, with JUUL devices particularly effective at recruiting teenagers to begin nicotine usage. A recent study found 27.5 percent of high school students and 10.5 percent of eighth graders currently use e-cigs, with more than half of both groups using JUUL as their preferred choice.
I have written repeatedly about the dangers of smoking cigarettes. Now, it appears that what was once considered a ‘less unhealthy’ practice has some negative impacts on our lungs.
E-cigarette vapor may have similar effects to cigarette smoke on bacteria associated with smoking-related illness such as chronic obstructive pulmonary disease (COPD) and asthma, according to a study published in Respiratory Research.
Although e-cigarettes are perceived as a safer alternative to cigarettes, recent research has suggested that acute lung disease may be associated with the use of nicotine-containing e-cigarettes, as well as conventional cigarettes. A team of researchers at the School of Pharmacy, Queen’s University Belfast, UK compared the effects of cigarette smoke and e-cigarette vapor on bacteria known to be associated with smoking-related chronic lung disease.

I feel very strongly about the dangers of smoking and have written about them repeatedly. It seems that some folks have switched over to vaping as a less unhealthy alternative. The more we learn about it, the less that seems to be true. Don’t smoke. Here is my Page on smoking – How many ways does smoking harm you?
Science hasn’t yet caught up with electronic cigarettes, leaving health care providers and users with many unknowns. But a new review of the research so far finds growing evidence that vaping can harm the heart and blood vessels.
“Many people think these products are safe, but there is more and more reason to worry about their effects on heart health,” said Loren Wold, senior author of the study, published today (Nov. 7, 2019) in the journal Cardiovascular Research. Continue reading
I have written repeatedly about the dangers of smoking cigarettes. Vaping, however, is new to me and I am virtually ignorant about it. I did post on it previously – Harmful vapors found in tank style electronic cigarettes.
Federal and state public health agencies are urging people to avoid vaping after a rash of related respiratory illnesses have resulted in 18 deaths and 1,080 lung injury cases across the United States. There have been 25 reported cases in Connecticut and one person has died from a vaping-associated lung injury. Here’s what you need to know about vaping-associated lung injury (also called vaping-related lung injury) and what you should do if you or a loved one develops worrisome symptoms.
What is vaping-associated lung injury?
Vaping is the act of inhaling the vapor created by liquid-filled cartridges used in battery-powered smoking devices called electronic cigarettes (e-cigarettes). Vaping-associated lung injury is damage to the lungs related to use of these vaping products. Continue reading
