The Importance of Research:

Given the ongoing debate surrounding vaping, rigorous scientific research is vital in unraveling the true health implications. Researchers are actively studying the effects of vaping on various aspects of health, including lung function, cardiovascular health, and the potential for developing respiratory diseases. Long-term studies are crucial to comprehensively understanding the risks associated with vaping and providing evidence-based guidelines.

Helping Smokers Quit:

While the safety of vaping remains uncertain, it is important to note that for individuals who already smoke traditional cigarettes, switching to vaping may offer some benefits. Research suggests that vaping can be an effective tool in smoking cessation, as it allows smokers to gradually reduce their nicotine intake. However, it is crucial to use vape as a temporary aid to quit smoking rather than as a long-term habit.

Quitting smoking can reduce the risk of lung cancer, heart disease, and many other diseases. However, many people find quitting smoking to be a challenging task. It is important to determine if using vape can assist in smoking cessation and whether users aiming to quit smoking with vape experience any adverse reactions.

Research on vape Smoking Cessation:

We conducted a randomized controlled trial, where the treatment individuals received was randomly assigned. Such studies typically provide the most reliable evidence regarding treatment outcomes.

We focused on:

  • The number of individuals who successfully quit smoking for at least six months.
  • The number of individuals reporting adverse reactions after using for at least one week.

Study Conditions and Elements:

This study involved 22,052 adult smokers.

The studies compared vaping with:

  • Nicotine replacement therapy, such as patches or nicotine gum.
  • Varenicline (a medication to aid smoking cessation).
  • Nicotine-free vape.
  • Other types of nicotine-containing vape (e.g., pod devices, mod devices).
  • Behavioral support, such as providing advice or counseling.
  • No support or only behavioral support for smoking cessation.

Study Results:

Compared to nicotine replacement therapy (2378 people) or nicotine-free vape (1447 people), using nicotine-containing vape may result in a higher number of people quitting smoking for six months or more.

Compared to no support or only behavioral support, nicotine vaping may help more people quit smoking (3126 people).

Out of every 100 people using nicotine vape for smoking cessation, 8 to 12 people may successfully quit smoking. In comparison, among 100 users of nicotine replacement therapy, only 6 may succeed, while among 100 users of nicotine-free vape, 7 may succeed, and among 100 individuals with no support or only behavioral support, only 4 may succeed.

We are uncertain whether there is a difference in the number of adverse reactions between users of nicotine vape and nicotine replacement therapy or no support or only behavioral support. Some evidence suggests that non-severe adverse reactions are more common in the group receiving nicotine vape compared to those receiving no support or only behavioral support. In studies comparing nicotine vape with nicotine replacement therapy, a small number of adverse reactions (including severe ones) were reported. There may be no difference in the number of severe adverse reactions between users of nicotine-containing and nicotine-free vape.

The most commonly reported adverse reactions to nicotine vape are throat or mouth pain, headache, cough, and nausea. As users continue to use nicotine vape, these adverse reactions gradually diminish.

How Reliable Are These Results?

Our results are based on several studies focusing on most outcomes, and for some outcomes, there is considerable variability in the data.

We found that nicotine vape may help more people quit smoking compared to nicotine replacement therapy. Nicotine-containing vape may be more effective than nicotine-free vape, but this conclusion requires further research for confirmation.

Studies comparing nicotine vaping with behavioral support or no support also show a higher quit rate among users of nicotine vape, but due to study design issues, the quality of the provided data is lower.

When more evidence becomes available, many results of our adverse reaction studies may change.

Key Information:

Nicotine vaping can help people quit smoking for at least six months. Evidence suggests they may be more effective than nicotine replacement therapy and possibly more effective than nicotine-free vape.

Nicotine-containing vaping may be more effective than no support or only behavioral support, and it may not be associated with severe adverse reactions.

However, more evidence is still needed, especially regarding the effectiveness of new vapes that have better nicotine release than older ones, as improved nicotine release may help more people quit smoking.


High-quality evidence indicates that nicotine-containing vaping increases the smoking cessation rate compared to nicotine replacement therapy, and there is moderate-quality evidence suggesting that nicotine-containing vaping increases the smoking cessation rate compared to nicotine-free vape. Evidence comparing nicotine-containing vape with standard treatments/no treatment also shows benefits, but the quality of this result is lower. Therefore, more research is needed to confirm this effect. Regarding data on adverse events, severe adverse events, and other safety indicators, confidence intervals are generally wide, and no differences in adverse events were observed between nicotine-containing and nicotine-free vape groups or between nicotine-containing vape and nicotine replacement therapy groups. The overall occurrence of severe adverse events in all study groups was very low. We found no evidence of severe harm caused by nicotine vape, but the longest follow-up time was two years, and the number of studies was limited.

Due to the low number of randomized controlled trials and often accompanied by a low event rate, the primary limitation of the evidence base remains imprecision, but further randomized controlled trials are underway. To ensure that this systematic review continues to provide the latest information for decision-makers, it will be kept up-to-date in real time.

Protecting Youth Health:

One of the most significant concerns surrounding vaping is its popularity among young people. The appealing flavors, marketing tactics, and misconceptions about its safety have attracted adolescents and young adults to try vaping. The presence of nicotine in vaping products can quickly lead to addiction, with potentially lifelong consequences. Implementing strict regulations, including age verification measures for purchasing and stricter marketing restrictions, is essential in protecting the health of our youth.

Remaining Informed:

As scientific knowledge about vaping continues to evolve, it is crucial to stay updated with the latest research and recommendations from reputable health organizations. Responsible reporting by media outlets can also play a significant role in disseminating accurate information and debunking myths. By remaining informed and critically evaluating the available evidence, individuals can make informed choices about their health and well-being.

The Future of Vaping:

The future of vaping remains uncertain, with ongoing research aiming to shed light on its long-term effects. Regulatory efforts are expected to intensify as policymakers seek to strike a balance between restricting access to vaping among youth while enabling smokers to access potentially less harmful alternatives. Continued scientific scrutiny, public education, and comprehensive regulations will be key in guiding the future of vaping and safeguarding public health.

In conclusion, vaping has sparked considerable interest and controversy. While it may offer an alternative for smokers seeking to quit traditional cigarettes, the health risks and addictive nature associated with vaping cannot be overlooked. Understanding the potential dangers, particularly among youth, and staying informed about evolving scientific research are essential steps in navigating this complex landscape. With continued research and vigilant regulation, we can strive to protect the health of individuals and promote evidence-based strategies for smoking cessation.
