Scientists analyzed global research and found that e-cigarettes with nicotine can help people stop smoking more effectively than other common quitting methods. This is especially true for high-quality studies.

Smoking is a major health risk, but quitting can be tough. Scientists wanted to see which methods work best to help smokers quit. They looked at 14 reviews of global research on nicotine replacement therapy (nicotine patches, gum, lozenges, etc.) and e-cigarettes. The results are clear: e-cigarettes with nicotine help people stop smoking better than other approaches.

The strongest evidence comes from high-quality studies that show nicotine e-cigarettes lead to higher quit rates. In contrast, lower-quality studies produced less consistent findings. Overall, the most reliable evidence points to nicotine e-cigarettes outperforming nicotine replacement therapy, non-nicotine e-cigarettes, and other alternatives.

Researchers also developed an 'Evidence and Gap Map' (EGM) to highlight areas where more research is needed. Currently, there are no high-quality systematic reviews directly comparing nicotine e-cigarettes with treatments like cytisine or bupropion. The EGM also indicates that evidence on serious adverse events linked to e-cigarettes remains uncertain.

The study's lead author, Dr. Angela Difeng Wu, emphasizes the need for future studies to better track potential risks and include populations from low-and middle-income countries.

Why It Matters

As India works to reduce smoking rates, understanding what methods work best can help policymakers develop effective programs to support smokers who want to quit.

Key Facts

• E-cigarettes with nicotine may help more people quit smoking than other common quitting methods
• The strongest evidence comes from high-quality studies that show nicotine e-cigarettes lead to higher quit rates
• Nicotine replacement therapy, non-nicotine e-cigarettes, and other alternatives are less effective for quitting smoking
• There is a need for future studies to better track potential risks and include populations from low-and middle-income countries
• The study's findings can inform the development of effective programs to support smokers who want to quit

Key Terms

Nicotine replacement therapy

A method that uses nicotine in a form other than smoking, such as patches or gum, to help people stop smoking

Implications

As India works to reduce smoking rates, understanding what methods work best can help policymakers develop effective programs to support smokers who want to quit.
