Daily use of electronic cigarettes is associated with nearly a doubling of the odds of a heart attack, according to a new study led by UC San Francisco.

Moreover, studies are increasingly documenting that instead of prompting smokers to switch from conventional cigarettes to e-cigarettes or quitting altogether as some scientists and policymakers had hoped, e-cigarettes are reducing the likelihood that people will quit smoking, while also expanding the nicotine market by attracting more youth to start.

The new study from UCSF and George Washington University drew upon National Health Interview Surveys of 20 involving 69,725 people, and controlled for conventional cigarette use, demographic characteristics such as age, gender and body mass index, and health characteristics such as hypertension, diabetes, and high cholesterol.

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). While we wait, can you explain how you controlled for conventional cigarette smoking?

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.“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. Someone who continues to smoke daily while using e-cigarettes daily has an increased risk of a heart attack by a factor of five. Are you saying you eliminated e-cig users who also had a history of smoking?

The work of the Center spans policy and historical research, economics, and science.

The work is designed to inform and improve the effectiveness of public health interventions to reduce tobacco use.

The report observed that there wasn’t yet evidence of the risks of heart, cancer or respiratory disease in people who used e-cigarettes, but found some support from animal studies that long-term use could increase those risks.

While noting that it could take decades for some health effects to appear, the National Academies report also showed a clear impact of e-cigarettes on young smokers: “Among youth – who use e-cigarettes at higher rates than adults do – there is substantial evidence that e-cigarettes use increases the risk of transitioning to smoking conventional cigarettes.” While e-cigarettes deliver lower levels of carcinogens than conventional cigarettes, they also expose users to high levels of ultrafine particles and other toxins that have been linked to increased cardiovascular and non-cancer lung disease risks -- which account for more than half of all smoking-caused deaths.
