Daily use of e-cigarettes doubles the risk of heart attack

23 August 2018

A new major American study of nearly 70,000 people has found that daily use of e-cigarettes doubles the risk of heart attack.[1]

The study conducted by researchers from the University of California San Francisco (UCSF) also found the combined use of e-cigarettes with conventional cigarettes is more dangerous than using either product alone, increasing the risk of heart attack five-fold.

“Most adults who use e-cigarettes continue to smoke cigarettes,” said senior author Professor Stanton Glantz, professor of medicine and director of the UCSF centre for Tobacco Control Research and Education.

“While people may think they are reducing their health risks, we found that the heart attack risk of e-cigarettes adds to the risk of smoking cigarettes.

“Using both products at the same time is worse than using either one separately,” said Professor Glantz.

This study, published on 22 August, adds to the growing evidence that e-cigarettes are harmful to health.

Leading Australian health authorities including the National Health and Medical Research Council (NHMRC) and the Therapeutic Goods Administration (TGA) have taken a precautionary approach to e-cigarettes, and a recent Australian Parliamentary Inquiry has recommended that the TGA continues to oversee the regulation of e-cigarettes.

The current public health evidence as reviewed by the NHMRC, the TGA, and other leading evidence-based agencies, does not support e-cigarette use in any form.

“It is crucial that the medical and scientific evidence on the effects of e-cigarettes be rigorously evaluated in terms of their overall impact on population health,” said Mr Maurice Swanson, Executive Director of the Australian Council on Smoking and Health.

Together with the increasing and alarming evidence that the use of e-cigarettes by young people is a precursor to the use of the conventional cigarettes, this new study from the US adds to the growing evidence of direct health harms, including increased risk of respiratory disease, cardiovascular disease and carcinogenesis.
