Former smokers using electronic cigarettes (e-cigs) report higher alcohol consumption. Social e-cig users, specifically, show increased risks for hazardous drinking patterns, warranting healthcare provider attention.
Area of Science:
- Addiction research
- Public health
- Behavioral science
Background:
- Electronic cigarettes (e-cigs) are increasingly used by former smokers.
- The relationship between e-cig use and alcohol consumption in former smokers is under-researched.
- Differences in alcohol use between e-cig users and non-users among former smokers remain unclear.
Purpose of the Study:
- To investigate differences in alcohol use between former smokers who use e-cigs and those who do not.
- To examine how regular versus social e-cig use relates to alcohol consumption patterns.
- To identify potential risks associated with e-cig use and alcohol intake in former smokers.
Main Methods:
- A sample of 198 former smokers was recruited online.
- Participants completed surveys assessing smoking status and alcohol use via timeline followback and the AUDIT.
- Statistical analyses examined the relationship between e-cig use status and alcohol consumption metrics.
Main Results:
- Former smokers who used e-cigs reported significantly higher total drinks and average drinks per drinking day compared to non-users.
- Among e-cig users, social users exhibited higher AUDIT scores, total drinks, and average drinks per drinking day.
- Social e-cig users were also more likely to be classified as hazardous drinkers.
Conclusions:
- Former smokers transitioning to e-cigs may exhibit elevated alcohol consumption.
- Social e-cig use is associated with a heightened risk for hazardous alcohol consumption patterns.
- Healthcare providers should consider e-cig use when assessing alcohol-related risks in former smokers.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
