Evaluating Interventions Aimed at Increasing Intention to Quit Vaping Among Adult E-cigarette Users - A Systematic Review
This systematic review of nine studies involving 4,752 adult e-cigarette users concludes that diverse interventions, including educational materials, health warnings, and interactive tools, effectively increase the intention to quit vaping, thereby informing future evidence-based cessation strategies.

For the past decade, a quiet revolution has reshaped how many people consume nicotine. Electronic nicotine delivery systems, commonly known as e-cigarettes or vaping devices, have surged in popularity, particularly among young people. While these devices are often viewed as a less harmful alternative for adult smokers who switch completely away from traditional tobacco, public health experts warn that their recreational use poses significant risks for those who do not already smoke. The concern is not just about immediate health effects, but about the potential for long-term dependence on nicotine and the possibility that users might eventually transition to more harmful products. Even for those who believe vaping helps them quit smoking, using these devices without medical guidance can sometimes hinder cessation efforts or encourage the use of both vaping and traditional cigarettes simultaneously. This complex landscape has created an urgent need for effective strategies to help current users stop. A critical step in this process is understanding the "intention to quit"—the mental resolve a person forms to stop using the product. If researchers can identify what successfully sparks that resolve, they can design better tools to help people break the habit.
A researcher led by Javad Heshmati at the University of Ottawa set out to find the most effective ways to strengthen this intention to quit among current e-cigarette users. They conducted a systematic review, a rigorous method of gathering and analyzing all available scientific studies on a specific topic to draw a clear, evidence-based conclusion. They searched through thousands of records from major medical databases, filtering them down to a final set of nine high-quality studies that directly measured how different interventions changed a user's desire to stop vaping. These studies, conducted between 2015 and 2024, involved a total of 4,752 participants and tested a wide variety of approaches, ranging from simple printed warnings to interactive digital games. The goal was not to measure whether people actually stopped vaping immediately, but to determine which methods successfully made them think more seriously about quitting.
The researcher discovered that several distinct types of interventions can significantly boost a user's motivation to quit. One of the most effective tools turned out to be the visual and textual warning labels found on packaging. Studies showed that when users were exposed to labels detailing the dangers of the vaping industry or specific harmful ingredients, their cravings for the product dropped noticeably. In one experiment, warnings about the industry itself reduced the urge to purchase e-cigarettes, while warnings about specific ingredients had an even stronger effect. Furthermore, the format of the warning mattered; pictures depicting health hazards were found to be more powerful than text-only messages. These visual warnings not only increased the desire to quit but also sparked more conversations among users about the addictive nature of the devices and the health problems they cause.
Beyond static labels, the review highlighted the power of storytelling and personal connection. Interventions that used "vicarious self-affirmation"—a technique where a person reads a story about a character who overcomes a challenge or wins an award—proved surprisingly effective. When young adult users engaged with these stories before reading anti-vaping messages, they were less likely to dismiss the warnings and more likely to report a strong intention to quit. In one study, nearly half of the participants who received this type of narrative affirmation expressed a heightened desire to stop, a rate significantly higher than those who received standard messages or no special intervention at all. This suggests that connecting with a story that affirms a person's values can lower their defenses against health warnings, making the message about quitting more persuasive.
Digital tools and public service announcements also played a vital role. The review examined interactive video games designed to teach young adults about the risks of vaping. While these games did not always result in an immediate, statistically significant drop in the willingness to try the devices among current users, they did successfully increase the players' perception of risk and their knowledge about what is actually in the vapor. Similarly, social media campaigns that focused on the harms of vaping, rather than just promoting a lifestyle, were shown to increase quit intentions. When messages were tailored to specific groups, such as young women, and focused on the negative health consequences, they were more effective at reducing the desire to purchase or use e-cigarettes than messages focused on pride or fitness.
The researcher noted that while these findings are promising, the evidence comes with some caveats. Many of the studies relied on participants reporting their own feelings and intentions rather than tracking whether they actually stopped using the devices over a long period. Additionally, the follow-up periods in many of the studies were short, meaning the long-term durability of these interventions remains uncertain. Despite these limitations, the review provides a robust summary of what works in the short term. It suggests that a combination of clear, graphic warnings, engaging narratives that connect with personal values, and interactive digital education can effectively shift the mindset of current vapers. By understanding that the intention to quit is a malleable state that can be influenced by the right message, public health officials and clinicians can develop more comprehensive strategies to help people navigate the challenges of vaping cessation.
