Abstract

Highlights: Validity of a purchase task to assess little cigar/cigarillo demand was supported. Demand for little cigars/cigarillos was associated with greater use and dependence. Intensity and price sensitivity were the most significant predictors. Abstract: Introduction: Hypothetical purchase tasks have been widely used to assess the reinforcing value of tobacco products. However, a task has not yet been validated for little cigars and cigarillos (LCCs), a popular tobacco product class among vulnerable populations. This study sought to validate the LCC Purchase Task (LCCPT) in a sample of experienced LCC smokers. Methods: Data were collected from 65 young adult (18–34 years) LCC and cigarette dual users (78.5% male) in Connecticut (2018–2020). Participants completed the usual-brand LCCPT for consumption in 24 h at increasing prices. We calculated four observed demand indices: intensity (consumption at $0), breakpoint (price after which consumption reaches 0), Omax (maximum daily expenditure), and Pmax (price at which daily expenditure was maximized). Two indices were estimated from demand curves: Q0 (predicted consumption as price approaches $0) and price-sensitivity (sensitivity to price increases). Spearman correlations and multivariable regressions examined the associations between demand indices, self-reported cigar use, and dependence. Results: Correlations were in expected directions. All indices except breakpoint and Pmax were positively correlated with use, and all indices were correlated with multiple measures of dependence. Overall, greater demand and expenditure for LCCs and lower sensitivity to price changes were correlated with greater use and dependence. In regression analyses intensity and price-sensitivity showed the strongest relationships with use and dependence. Conclusions: The validity of the LCCPT was supported in a sample of experienced LCC smokers. This instrument can be incorporated into other protocols to assess the abuse liability of LCCs.
