VOCs are a broad group of gases found in many common items, such as cleaning products, paint, cigarettes, vehicle exhaust, pesticides, and other substances. According to
“Pod-based e-cigarettes are commonly marketed to youth and young adults, as well as people who are trying to quit or cut down on regular cigarette smoking,” said the study’s lead author.
As part of the American Heart Association
The study included 106 young adults, aged 18 to 45, with no cardiovascular disease or risk factors (no diagnosis or increased risk of hypertension, type 2 diabetes or dyslipidemia (high cholesterol)). Participants were recruited between 2019 and 2021 at
About 45% (48) of participants used pod e-cigarettes; 20% (21) smoked combustible cigarettes; and 35% (37) reported not using tobacco in any form. At the time of the study, 37% of pod e-cigarette users said they had never smoked traditional cigarettes; 64% used e-cigarettes exclusively; and 36% used both e-cigarettes and combustible cigarettes.
The participants’ vascular function (functioning of the arteries and veins that move blood throughout the body) and blood pressure were measured before and after using their favorite tobacco product for 10 minutes. Measurements were taken in one day, during one clinic visit for each participant. Vascular function was measured by examining flow-mediated dilation of the brachial artery – the widening of the artery in the arm in response to increased blood flow – both before and 30 minutes after the participants used their preferred tobacco product, with a single measurement taken at both time points. Blood pressure and heart rate were measured 10 minutes after the participants used their preferred tobacco product, with the researchers recording the average of three readings before and after using the product. Urinary VOC levels were measured at baseline and one hour after using e-cigarettes or traditional cigarettes.
The results revealed that young adults who use pod e-cigarettes experienced changes in blood vessel health similar to traditional cigarette smokers:
“Our results demonstrate that pod-based e-cigarette use has long- and short-term effects on the vascular system in healthy young adults, including those who have only smoked e-cigarettes. and have never smoked combustible cigarettes. These results indicate that e-cigarettes release chemicals that are toxic to blood vessels, and the use of pod e-cigarettes may be associated with harm,” said Majid said Long-term effects included participants’ baseline readings for blood pressure and heart rate and short-term effects included those readings after participants used e-cigarettes or combustible cigarettes.
The use of pod e-cigarettes has increased among youth and young adults in recent years. “Youth and young adults should avoid using tobacco products, including pod e-cigarettes, as they can harm blood vessel health. Establishing regulations that make it harder for young people to start using e-cigarettes is an important part of achieving a tobacco-free future,” she continued. “We also need better approaches to help people stop using all tobacco products and expand support and access to cessation programs and medications.
Study limitations included participants using their own tobacco product, which made it difficult to isolate the effects of each of the products’ individual components, such as nicotine levels or flavors, as well as differences in vascular function. in each participant that may be associated with the use of specific types or brands of tobacco products. Additionally, most participants used mint-flavored pods, and larger studies may be needed to capture the differences associated with different flavor types.
