E-Cigarette Withdrawal Symptoms: Prevalence and Severity
Research shows that withdrawal symptoms can occur when people stop using e-cigarettes, but the severity and type of symptoms can vary depending on user history, device type, and context. Both physical and psychological symptoms have been reported, though they are often less intense than those experienced with traditional tobacco cigarettes Hughes2019Hughes2019.
Physical and Psychological Withdrawal Symptoms
Common withdrawal symptoms from e-cigarette abstinence include cravings for e-cigarettes and tobacco cigarettes, mood swings, anxiety, impulsivity, and anhedonia (loss of pleasure) . Physical symptoms such as increased appetite and decreased heart rate have also been observed . In studies of users who stopped e-cigarettes during intermittent fasting, most reported only weak physical and psychological withdrawal symptoms .
Comparison to Tobacco Cigarette Withdrawal
The severity of withdrawal from e-cigarettes is generally somewhat less than that from daily tobacco cigarette use, but it is still significant enough to indicate physical dependence Hughes2019Hughes2019. Fewer e-cigarette users report withdrawal symptoms compared to tobacco cigarette users, and the symptoms tend to be milder . In dual users (those who use both e-cigarettes and tobacco cigarettes), continued tobacco use appears to reduce e-cigarette withdrawal symptoms, but not vice versa .
Withdrawal in Never-Smokers and Former Smokers
Even never-smokers who use e-cigarettes daily can experience withdrawal symptoms when they stop, though these symptoms are usually mild and may not be clinically significant . Former smokers who switch to daily e-cigarette use also show withdrawal symptoms upon cessation, indicating that dependence can transfer from tobacco to e-cigarettes .
Device Type and Withdrawal Symptom Relief
The type of e-cigarette device can influence withdrawal symptom relief. Second-generation e-cigarettes are more effective at reducing nicotine withdrawal symptoms than first-generation devices . Additionally, the visual appearance of the device can affect withdrawal and craving, especially for new users; devices that look more like traditional cigarettes may provide greater relief .
Cognitive and Affective Changes During Withdrawal
Withdrawal from e-cigarettes can lead to cognitive and affective changes, such as anxiety, depression, and memory deficits. These symptoms can persist or even appear late after stopping long-term e-cigarette use, as shown in animal studies . In humans, acute use of nicotine-containing e-cigarettes can improve working memory and reduce withdrawal symptoms, especially in males .
Interventions to Reduce Withdrawal Symptoms
Preliminary research suggests that cannabidiol (CBD) may help reduce the severity of nicotine withdrawal symptoms and anxiety during e-cigarette abstinence . Behavioral strategies, such as keeping busy, are also commonly used by individuals to manage withdrawal symptoms during periods of abstinence, such as intermittent fasting .
Conclusion
E-cigarette withdrawal symptoms are real and can include both physical and psychological effects, though they are often milder than those from tobacco cigarettes. The severity of symptoms depends on user history, device type, and context. Awareness of these symptoms and potential interventions, such as CBD or behavioral strategies, may help individuals manage withdrawal and support cessation efforts.
