Many of the skeptical cardiologist’s patients managed to quit cigarette smoking by using e-cigarettes . They often continue to vape, prolonging their addiction to nicotine but overall I felt they were probably better off than smoking cigarettes. However, a couple of recent articles have me very concerned about the overall effect of e-cigarettes on public health.
The first article came from the PR department at UCSF with the headline:
Smoking E-Cigarettes Daily, Doubles Risk Of Heart Attacks”
It focused on an abstract presented in Baltimore in February 2018 by Stanton Glantz, UCSF professor of medicine and director of the UCSF Center for Tobacco Control Research and Education. The abstract (paper yet to be published) was an observational study of about 70,000 individuals. Since it was observational the causality implied by the headline is not justified but the findings are still worrisome:
When adjusted for other risk factors, daily e-cigarette use was associated with significantly increased odds (Odds Ratio: 1.79) of having had a heart attack (myocardial infarction), as was daily conventional cigarette smoking (OR: 2.72). Former and occasional e-cigarette use were not associated with significant changes in the odds of having had a heart attack, while the same categories of cigarette smoking were associated with smaller increases in risk than for current smokers.
So e-cigarettes might be safer than real cigarettes but if you don’t quit smoking you are worse off:
“E-cigarettes are widely promoted as a smoking cessation aid, but for most people, they actually make it harder to quit smoking, so most people end up as so-called ‘dual users’ who keep smoking while using e-cigarettes,” said Glantz. “The new study shows that the risks compound. Someone who continues to smoke daily while using e-cigarettes daily has an increased risk of a heart attack by a factor of five.
Juul and The Rise In Teenage Vaping
The second article was from The New Yorker and is fascinating. Entitled “The Promise of Vaping and the Rise of Juul.” , it details an alarming rise in teenage vaping which often involves a particular brand of e-cigarette, Juul, which resembles a flash drive.
To Juul (the brand has become a verb) is to inhale nicotine free from the seductively disgusting accoutrements of a cigarette: the tar, the carbon monoxide, the garbage mouth, the smell. It’s an uncanny simulacrum of smoking. An analyst at Wells Fargo projects that this year the American vaporizer market will grow to five and a half billion dollars, an increase of more than twenty-five per cent from 2017. In the latest data, sixty per cent of that market belongs to Juul.
Scientists Warn of E-cigarette Health Risks
In March, a congressionally mandated report on the health effects of e-cigarettes from the National Academies of Sciences, Engineering, and Medicine concluded:
Evidence suggests that while e-cigarettes are not without health risks, they are likely to be far less harmful than conventional cigarettes, the report says. They contain fewer numbers and lower levels of toxic substances than conventional cigarettes, and using e-cigarettes may help adults who smoke conventional cigarettes quit smoking.
With respect to cardiovascular diseases, their conclusions were:
- We don’t currently have evidence that e-cigarettes increase risk of stroke or heart attack or subclinical atherosclerosis
- There is good evidence that in the short term the nicotine in e-cigarettes raises systolic and diastolic blood pressure and heart rate
- There is limited evidence that e-cigarettes increase biomarkers of oxidative stress, increase endothelial dysfunction and arterial stiffness. All of these factors are known to contribute to the development of atherosclerosis.
Long term, it is anyone’s guess what the consequences of vaping on the cardiovascular system will be.
As the New Yorker article makes abundantly clear, however, the youth of America are taking up vaping and Juuling increasingly and the National Academies are appropriately worried:
However, their long-term health effects are not yet clear. Among youth — who use e-cigarettes at higher rates than adults do — there is substantial evidence that e-cigarette use increases the risk of transitioning to smoking conventional cigarettes
Are Your Kids Vaping?
In 2015 there was a 40% chance your middle school or high school child had used e-cigarettes. The chart below from the CDC shows how rapidly rates are climbing.
The surgeon general/CDC issued a warning in 2016, writing:
E-cigarette use among U.S. youth and young adults is now a major public health concern. E-cigarette use has increased considerably in recent years, growing an astounding 900% among high school students from 2011 to 2015. These products are now the most commonly used form of tobacco among youth in the United States, surpassing conventional tobacco products, including cigarettes, cigars, chewing tobacco, and hookahs. Most e-cigarettes contain nicotine, which can cause addiction and can harm the developing adolescent brain.
Compared with older adults, the brain of youth and young adults is more vulnerable to the nega- tive consequences of nicotine exposure. The effects include addiction, priming for use of other addic- tive substances, reduced impulse control, deficits in attention and cognition, and mood disorders. Furthermore, fetal exposure to nicotine during pregnancy can result in multiple adverse consequences, including sudden infant death syndrome, altered corpus callosum, auditory processing deficits, effects on behaviors and obesity, and deficits in attention and cognition. Ingestion of e-cigarette liquids con- taining nicotine can also cause acute toxicity and possibly death if the contents of refill cartridges or bottles containing nicotine are consumed.
Stealth Vaping Devices
Vaping devices no longer clearly look like cigarettes. Here are some examples from the CDC report.
Note, however, that the Juul is not depicted.
It doesn’t look like a cigarette or a device that would be facilitating your child’s addiction to nicotine. And it has a USB port so it can be recharged from a laptop.
This wasn’t an issue as far as I can tell when my children were teens but I’m pretty sure if I had teenagers I would ban vaping and would confiscate anything that resembled an e-cigarette including flash or thumb drives that aren’t flash or thumb drives.

>there is substantial evidence that e-cigarette use increases the risk of transitioning to smoking conventional cigarettes
Jesus… that’s some sad irony, or something. E-cigarettes were purported to be “smoking cessation aids” and now are leading to children smoking who more than likely would otherwise have never started smoking. Can’t help but wonder if that was their plan all along.
You are incorrect on all counts, the result of anti vaping brainwashing. Please check your facts for bias. Jesus has nothing to do with it, only malicious humans with an agenda!
You need to understand you are living in the USA, where Stanton Glantz and his ilk have fouled your information waters. In Europe, the situation is really different with much proper, unbiased research being conducted into the safety of e cigarettes/vaping and proper science coming out. You cannot believe anything offered to you by Tobacco Control. You must avoid being brain-washed by their “Smokefree” dogma. Be aware. Be warned. Find your science in Europe.
Interesting comments. I have a lot of respect for Stanton Glantz as I studied, in detail his “Primer on Biostatistics” when I was doing research. This is what wikipedia says of him: “Often called the “Ralph Nader of the anti-tobacco movement,” Glantz is an activist for nonsmokers’ rights and an advocate of public health policies to reduce smoking. He is the author of four books, including The Cigarette Papers and Primer of Biostatistics. Glantz is also a member of the UC San Francisco Cardiovascular Research Institute and Institute for Health Policy Studies and co-leader of the UCSF Comprehensive Cancer Center Tobacco Program. He was elected to the Institute of Medicine in 2005.”
So, it’s hard to understand how he is fouling “my information waters.” Perhaps you can provide us with some references on the unbiased research coming from Europe.
