Addictive Potential of LCCs in Dual Users

March 5, 2026 updated by: Erin Mead-Morse, UConn Health

Addictive Potential of Little Cigars/Cigarillos in Dual Users: Effect by Flavor and Gender

This study is about whether or not little cigars and cigarillos cause or maintain addiction, and if flavors, such as fruit, make them more addictive. The purpose of this study is to understand the addiction potential of little cigars and cigarillos compared to cigarettes in young adults who smoke both products. This study will also look at the differences between men and women. In the rest of this form, little cigars or cigarillos will be referred to as LCCs.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Flavored LCCs
Half of the group will start with a flavored little cigar/cigarillo (LCC) and cross over to unflavored LCC. The LCCs will be a popular brand already available for sale on the market.
Flavored and unflavored LCCs that are currently available for purchase
Experimental: Unflavored LCCs
Half of the group will start with an unflavored little cigar/cigarillo (LCC) and cross over to flavored LCC. The LCCs will be a popular brand already available for sale on the market.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Demand Elasticity
Time Frame: Post-treatment (after being assigned to use it for 7 days)
Hypothetical consumption of LCCs as prices increase. These are the model-adjusted predicted mean values of elasticity, adjusted for covariates. It is the expected change in consumption for a one unit change in price.
Post-treatment (after being assigned to use it for 7 days)
Demand Intensity
Time Frame: Post-treatment (after 7 days of being assigned to condition)
Hypothetical consumption when free. These are the model-adjusted predicted mean values of intensity, adjusted for covariates.
Post-treatment (after 7 days of being assigned to condition)
