LSU Health New Orleans Review Suggests HNB Tobacco Products

A review of heat-not-burn (HNB) tobacco products from the laboratory of Dr. Jason Gardner, Professor of Physiology at LSU Health New Orleans School of Medicine, reports an association with elevated blood pressure, increased heart rate, cell death, and circulatory dysfunction shown by early studies. Additionally, chemicals found in the vapor produced by HNB devices have previously been shown to impair lung function, put users at risk of heart attack and stroke, cause cancers, increase circulating low-density lipoprotein (“bad cholesterol”) and more. The review is published in the American Journal of Physiology-Heart and Circulatory Physiology, available online here.To get more news about Hitaste, you can visit official website.
Cigarette smoking continues to decline globally, but vaping is becoming more popular, especially among youth and young adults. Recent cases of vaping-associated lung injury may lead consumers to try new methods of nicotine consumption. Heat-not-burn products are newcomers to the U.S. market. They produce nicotine-containing vapor by heating tobacco at low temperatures. This is in contrast to cigarettes that use high temperatures to burn tobacco and produce smoke or e-cigarettes that heat e-liquid, which contains nicotine but not tobacco, to produce vapor.

Due to the novelty of these products, little research has been conducted on HNB devices. The Gardner lab compiled findings from dozens of human, animal, and cell culture studies to determine associated inhalants and potential health effects, with an emphasis on the heart, arteries, and veins. Findings suggest that HNB devices produce fewer pollutants than cigarettes, but it is unclear if these reductions are reflected in health outcomes of users.
“While relatively new to the U.S., heat-not-burn products have become popular in other countries including Japan, Italy, and Korea,” notes lead author Nicholas Fried, an MD/PhD student in Dr. Gardner’s laboratory. “These products are often touted as a replacement for cigarettes, but the evidence does not necessarily support that. Almost all Korean users of heat-not-burn products are also current cigarette smokers; nearly half of Italian users had never even smoked a cigarette. These trends worryingly suggest that heat-not-burn may be a compliment or gateway to cigarette smoking, rather than a ‘healthy’ replacement. More troubling, nearly 2% of high school students in the U.S. are already using HNB tobacco products, and surveys show that 25% of students are susceptible to trying them. There is potential for these devices to become a significant public health issue.”
