Abstract
INTRODUCTION
Cigarillos dominate the US cigar market, and young adults largely drive use. While young adults prefer flavoured to non-flavoured cigarillos, especially those flavoured to taste like fruit or other sweets, the factors that underlie this preference have received little attention. We sought to determine if key indicators of abuse liability, the rewarding and reinforcing effects, are greater for sweet versus non-flavoured cigarillos.
METHODS
Young adults (18-24 years old) completed three laboratory visits assessing the subjective rewarding value (exposure paradigm), relative reinforcing value (computerised choice task) and absolute reinforcing value (ad libitum cigarillo smoking session) of sweet-flavoured versus non-flavoured cigarillos. General linear regression models were fit with the appropriate family link for each outcome measure.
RESULTS
Young adults rated sweet-flavoured cigarillos as more rewarding (estimated marginal mean (EMM) =4.52, 95% CI 4.00 to 5.03) than the non-flavoured cigarillo (EMM=3.31, 95% CI 2.80 to 3.83; B=1.20, 95% CI 0.80 to 1.60, p<0.001). The reinforcing value of sweet-flavoured cigarillos, measured by break point, was higher relative to non-flavoured cigarillos (6.34 out of 10), especially among young adults with a preference for flavoured cigarillos (B=1.94, 95% CI 0.71 to 3.18, p=0.003). Young adults took 1.9 times the number of puffs (35.75 vs 19.95) from sweet-flavoured cigarillos compared with non-flavoured cigarillos (Rate Ratio =1.94, 95% CI 1.30 to 2.90, p<0.001).
CONCLUSIONS
Sweet flavouring increases the abuse liability of cigarillos among young adults as reflected in greater liking, motivation to use and actual use. Banning sweet flavouring in cigarillos may diminish their use in young adults.Trial registration number CT.gov (NCT05092919).
