NOW OPEN ACCESS: E-cigs have similar risks to cigs for some diseases and nearly as high for others. Dual use riskier than smoking alone

NEJM Evidence has graciously made our recent paper, “Population-Based Disease Odds for E-Cigarettes and Dual Use versus Cigarettes,” open access so that anyone can read and download it for free. As described in more detail in my blog post on the paper, it uses data from 107 population epidemiology studies of the association between e-cigaretteContinue reading “NOW OPEN ACCESS: E-cigs have similar risks to cigs for some diseases and nearly as high for others.

Smoking cessation quickly reduces mortality, within 3 years

It’s been long-established that quitting smoking prolongs life and that quitting young (below about 40) eliminates all or almost all the mortality costs of smoking. The new paper Smoking Cessation and Short- and Longer-Term Mortality by Eo Rin Cho and colleagues extends this case to more recent data and from several countries. While they confirmContinue reading “Smoking cessation quickly reduces mortality, within 3 years”

More information on how ecigs increase cardiovascular disease risk

The evidence that e-cigarette use is associated with increased cardiovascular disease keeps accumulaing, together with studies on the specific pathophysiological mechanisms through which e-cigarette use increases disease risk. The recent review by Huiqi Zong, Zhekai Hu and colleagues, Electronic cigarettes and cardiovascular disease: epidemiological and biological links, is the most recent summary of this evidence.Continue reading “More information on how ecigs increase cardiovascular disease risk”

FDA needs to reconsider its promotion of the “continuum of risk” for e-cigarettes

As of February 22, 2024, the FDA was continuing to embrace the idea that there is a “continuum of risk” with combusted tobacco as the riskiest and e-cigarettes being substantially less risky. As a result, FDA promotes e-cigarettes as a way for smokers to reduce risk. This view is based on the fact that e-cigarettesContinue reading “FDA needs to reconsider its promotion of the “continuum of risk” for e-cigarettes”

Cannabis use linked to increase in heart attack and stroke risk

Many people think cannabis is “medicine” and so ignore its heath effects. Abra Jeffers, Amy Byers, Salome Keyhani and I just published Association of cannabis use with cardiovascular outcomes among US adults in the Journal of the American Heart Association that found that cannabis use is associated with adverse cardiovascular events with heavier use (moreContinue reading “Cannabis use linked to increase in heart attack and stroke risk”

E-cigs have similar risks to cigs for some diseases and nearly as high for others. Dual use riskier than smoking alone

It is an article of faith among e-cigarette advocates that they are substantially less risky than cigarettes. Rather than being based on the actual associations between e-cigarette use and disease, this belief is based on the fact that e-cigarettes do not burn tobacco, so avoid the toxic combustion products that cigarettes produce. In recent years,Continue reading “E-cigs have similar risks to cigs for some diseases and nearly as high for others. Dual use riskier than smoking alone”

COP10 delegates need to base decisions on latest e-cig evidence, not the same old studies e-cig advocates promote

In the lead up to the WHO Framework Convention on Tobacco Control Tenth Conference of the Parties that starts today, advocates for e-cigarettes and other “reduced harm” tobacco products have been busy again arguing that delegates should embrace these products. In reviewing some of this material, I have been struck by the fact that theirContinue reading “COP10 delegates need to base decisions on latest e-cig evidence, not the same old studies e-cig advocates promote”

E-cigarettes associated with heart attacks in never smokers

Since we published the first study demonstrating that e-cigarette use was associated with higher odds of having had a heart attack, e-cigarette advocates have argued that this association was an artifact of current or former cigarette smoking or “reverse causation” due to smokers starting to use e-cigarettes after they had a heart attack.  Now TalalContinue reading “E-cigarettes associated with heart attacks in never smokers”

E-cigs associated with increased heart attacks; dual use is worse

Muhammad Talal Ashraf and his colleagues recently published “Association between e‑cigarette use and myocardial infarction: a systematic review and meta‑analysis” that pools the results of epidemiological studies and found that overall e-cigarette users are more likely to have had heart attacks than nonusers (odds ratio [OR] 1.44; 95% CI 1.22-1.74). They also found that dualContinue reading “E-cigs associated with increased heart attacks; dual use is worse”

Two new studies link marijuana with heart disease, including in non-tobacco smokers

Two papers are being presented today (November 13, 2023) at the American Heart Association Annual Scientific Sessions that show marijuana use is associated with increased cardiovascular disease. The first, Daily Marijuana Use is Associated With Incident Heart Failure: “All of Us” Research Program reports a 34% increased risk of incident heart failure in daily recreationalContinue reading “Two new studies link marijuana with heart disease, including in non-tobacco smokers”
