Factors Associated with Past 30-day Abstinence from Cigarette Smoking in a Non-Probabilistic Sample of 15,456 Adult Established Current Smokers in the United States Who Used JUUL Vapor Products for Three Months

Summary of Study

Bottom Line: Between 28.3% and 47.1% of adult smokers quit smoking cigarettes completely after using a JUUL vaporizer for 3 months. More frequent use of a JUUL and primary use of JUUL flavors appear to be important to new JUUL users’ chances of quitting smoking. The impact of banning retail sales of flavored JUULpods on adult smokers’ likelihood of quitting should be closely assessed.

Since their introduction to the US market in 2007, e-cigarettes have rapidly grown in popularity among adults in several countries as an alternative to smoking conventional cigarettes and the increasing use of e-cigarettes has been associated with significant increases in rates of smoking cessation. E-cigarettes are now the most popular assisted method of quitting smoking in the USA.

The ability to inhale e-cigarette vapor aerosol in a vast and growing variety of characterizing flavors—a distinguishable taste or aroma, other than the taste or aroma of tobacco—is thought to be a major feature accounting for the appeal of e-cigarettes to adult smokers as an alternative to continuing to smoke cigarettes.

Past 30-day smoking abstinence at the 3-months assessment was reported by 28.3% of the intent-to-treat (ITT) sample and 47.1% of an efficacy subset sample that completed the 3-months assessment. 

Eight variables were significant in predicting smokers’ likelihood of reporting past 30-day abstinence from smoking after using a JUUL vaporizer for 3 months. The following five were associated with significantly higher odds of not having smoked in the 30 days prior to the 3-month assessment: 

  1. Daily use of a JUUL vaporizer in the past month.
  2. Primary use of Mint or Mango flavored JUULpods. 
  3. Exclusive use of JUULpods in characterizing flavors. 
  4. Purchasing one’s first JUUL Starter Kit in a retail store.
  5. Purchasing one’s first JUUL vaporizer to help to quit smoking completely. 

The following three variables were associated with significantly lower adjusted odds of not having smoked any cigarettes in the 30 days prior to the 3-month assessment:

  1. Smoking regularly for more than 20 years.
  2. Smoking more cigarettes per day and smoking on more days in the 30 days before purchasing one’s first JUUL Starter Kit.
  3. Primary use of Classic Tobacco flavored JUULpods.

Compared to those who primarily used Virginia Tobacco flavored JUULpods in the 30 days prior to the 3-month assessment, those who primarily used Mint flavored JUULpods or Mango flavored JUULpods were 37% and 26% more likely, respectively, to have not smoked a cigarette in the 30 days prior to the 3-month assessment. Mint and Mango were the most common primary flavors, with primary users of Mint and Mango flavored JUULpods in the 30 days prior to the 3-month assessment together accounting for 49.8% of all participants who had not smoked a cigarette in the 30 days prior to the 3-month assessment, and 44.7% of all participants who completed the 3-month assessment.

Findings:

  • Between 28.3% and 47.1% of adult smokers quit smoking cigarettes completely after using a JUUL vaporizer for 3 months.
  • Purchasing one’s first JUUL Starter Kit in a retail store is strongly associated with higher smoking quit rates. 
  • These findings should inform regulations on vape shop and convenience store sales of JUUL devices.
