Are Electronic Cigarettes Harmful, and Can They Help You Quit Smoking?

Are electronic cigarettes harmful, and can they help you quit smoking? Electronic cigarettes are promoted and used as harm reduction and smoking cessation products in many countries around the world. However, many countries, especially those with high tobacco revenues, have a fluctuating attitude towards electronic cigarettes. Are electronic cigarettes an important tool for quitting smoking or a newly emerging public health issue?

According to ongoing research by Olivia Wackowski, an assistant professor at the Rutgers School of Public Health's Department of Social and Behavioral Health Sciences and Tobacco Research Center, public perceptions of the safety of these new products mainly stem from advertising, packaging, and media coverage.

Wackowski's research on tobacco communication, product and risk perception, and product usage trends is crucial for informing regulatory science, as it relates to the FDA's authority over tobacco product regulation.

Wackowski discusses how the market surge of this broad category of electronic devices—from “cigars” that resemble traditional cigarettes to larger “vaporizers,” “tank systems,” and “pod” systems popularized by brands like JUUL—presents new challenges for public health.

Are electronic cigarettes harmful?

Because electronic cigarettes do not contain or burn tobacco, they do not expose users to the same quantity and levels of chemicals and toxins found in cigarette smoke. However, they may contain nicotine, which is an addictive substance that can harm the developing brains of adolescents. The aerosol produced by electronic cigarettes may contain chemicals and toxins, although at lower levels than those found in cigarette smoke.

As electronic cigarettes are a new product, we do not fully understand the long-term risks associated with them, nor do we know the safety of inhaling the flavorings and additives in electronic cigarettes. While electronic cigarettes should not be considered safe, some public health experts believe they can play a meaningful role in reducing harm for smokers who no longer use traditional tobacco products. However, a concerning issue is that non-smokers and young people may start using these products for recreational purposes, attracted by flavors or trendy designs.

What is the public perception of electronic cigarettes?

In recent years, perceptions of the harms of electronic cigarettes seem to have changed, with the public increasingly inclined to view electronic cigarettes as harmful as traditional cigarettes. However, research shows that young people, electronic cigarette users, and smokers are more likely than the general public to believe that electronic cigarettes are less harmful to health than traditional cigarettes. In fact, this is one of the reasons people use electronic cigarettes.


How do packaging, advertising, and media portrayals change public perceptions of electronic cigarettes?

Product advertising can enhance people's perceptions of electronic cigarettes, brand awareness, and product trial. Research indicates a correlation between exposure to electronic cigarette advertisements and interest in using electronic cigarettes. For example, the current popularity of the JUUL brand may be linked to its bright, modern advertising style and the product's design, which is small, stylish, and resembles a USB flash drive.

Conversely, the increasing news coverage of electronic cigarettes may lead to a growing negative perception of them. Research at our Tobacco Research Center indicates that news reports about electronic cigarettes are more likely to discuss potential risks than the benefits of reduced harm for smokers.

How do the sales, marketing, and production regulations of electronic cigarettes differ from those of tobacco products?

The minimum legal sales age for electronic cigarettes varies between 18 and 21 years across different states. The FDA has not yet imposed any restrictions on the marketing channels for electronic cigarettes—you may have noticed broadcast or television advertisements—but since the 1970s, the FDA has banned such advertising for cigarettes. However, electronic cigarette advertisements can no longer claim that these products have improved risks compared to traditional cigarettes without first obtaining FDA approval. Although the FDA banned flavors in regular cigarettes in 2009, it has not prohibited flavors in electronic cigarettes. #p#分页标题#e#

Do electronic cigarette packages need product warning labels?

Until recently, electronic cigarette products and advertisements were not required to carry warnings, although some companies voluntarily did so. However, new FDA warning requirements that took effect on August 10, 2018, mandate that electronic cigarette packaging and advertisements must include a prominent warning stating that they contain nicotine, an addictive chemical. This is important because research continues to show that some young people are unaware that the electronic cigarettes they have used contain nicotine.

However, research I conducted with experts in tobacco control communication suggests that concerns about nicotine addiction warnings may not resonate sufficiently with young people—the primary audience for electronic cigarette warnings. If it aligns with public health, the FDA may propose additional warnings in the future. My current research explores the impact of other warning themes on young people, such as the dangers of nicotine on adolescent brain development and warnings about potentially harmful chemicals in electronic cigarettes. We are also investigating whether the FDA's nicotine addiction warnings can be enhanced by pairing them with simple images, such as a yellow triangle with an exclamation mark, which is a recognizable warning symbol.

Nevertheless, warning labels on electronic cigarettes present an information challenge: they should inform consumers about the risks of electronic cigarettes, deter non-smokers from using them, while not discouraging current smokers from using these products to quit smoking and reduce harm.
