Cigar use progression among new cigar initiators: A two-part growth curve analysis among a youth and young adult cohort.

This study is the first to examine progression of cigar use among youth and young adults who have newly initiated cigars. Results show a high probability current cigar use within six months of initiation followed by a rapid decline and stabilization over time. Frequency increases among those who continue using cigars. Males, younger users and current cigarette smokers had the highest risk for cigar progression over time. Findings emphasize the need for targeting interventions by age, stage of use, cigarette, other tobacco and marijuana use and key sociodemographics to interrupt use pathways.
