Abstract
INTRODUCTION
Cigarette and little cigar/cigarillo (LCC) dual use is popular among young people and poses a substantial health risk. What remains unclear is the abuse liability of LCCs vs. cigarettes, LCCs' substitutability for cigarettes, and the influence of flavors on the abuse liability and substitutability of LCCs.
METHODS
Sixty-five young adults (18-34 years) who dual use completed hypothetical purchase tasks to measure consumption of usual brand cigarettes and LCCs in 24 hours at increasing prices (demand), and LCC consumption at increasing cigarette prices (substitution). Three demand indices were calculated from raw data: breakpoint (price after which consumption reaches 0), Omax (maximum daily expenditure), and Pmax (price at maximum expenditure). Two indices were estimated using nonlinear mixed-effects modeling: intensity (consumption when free) and price-sensitivity (rate of decline in consumption as price increases). Substitution, and associations of flavored use with demand and substitution, were estimated using linear mixed models.
RESULTS
Results indicated similar abuse liability for LCCs and cigarettes. Intensity was greater for cigarettes, but price-sensitivity was similar. Flavored LCC use was associated with lower price-sensitivity and greater intensity than unflavored. LCCs were significant substitutes for cigarettes, but the effect was small. Flavored use was not associated with substitution.
CONCLUSIONS
Among young adults who dual use, LCCs and cigarettes had similar abuse liability, and those who used flavored had higher demand for their LCCs. A flavored cigar ban, as well as targeted prevention and cessation services for those who smoke flavored LCCs, may be important for reducing dual use in young adults.
IMPLICATIONS
Cigarette and LCC dual use remains high among young adults. Using hypothetical purchase tasks with young adults who dual use, LCCs had abuse liability similar to cigarettes, but were only modest substitutes for cigarettes. Participants who used flavored LCCs reported greater abuse liability than those who used unflavored, but not greater substitution for cigarettes. Prevention and cessation services are needed to target LCCs in young people, particularly those smoking flavored products. A flavored cigar ban may help to reduce their demand.
