Consumer preferences for electronic cigarettes: results from a discrete choice experiment

Area of Science:

• Public Health
• Consumer Behavior
• Regulatory Science

Background:

• E-cigarettes pose regulatory challenges due to market diversity and rapid evolution.
• Understanding consumer perceptions of e-cigarette characteristics is crucial for effective policy.

Purpose of the Study:

• To investigate how e-cigarette product attributes influence consumer perceptions and trial intentions in Canada.
• To identify key characteristics that drive consumer choices regarding e-cigarettes.

Main Methods:

• An online discrete choice experiment involving 915 Canadians aged 16 and older.
• Analysis of stated preferences across three subpopulations: non-smoking youth/young adults, smoking youth/young adults, and smoking adults.
• Multinomial logit regression to analyze the impact of flavour, nicotine content, health warnings, and price on trial interest, harm perception, and quit aid usefulness.

Main Results:

• Health warnings were the most influential attribute for trial intentions (42%) and perceived quit aid efficacy (39%).
• Flavour (36%) and health warnings (35%) significantly predicted perceptions of e-cigarette harm.
• Consumer choices varied across different subpopulations, indicating diverse trade-offs.

Conclusions:

• Consumers make distinct trade-offs regarding e-cigarette attributes, with significant variations among demographic groups.
• Health warnings and flavour emerge as critical attributes influencing consumer decisions.
• These findings suggest that health warnings and flavour characteristics should be prioritized in e-cigarette regulatory frameworks.
