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.

Description
Inclusion Criteria:
- Current regular dual user of little cigars/cigarillos (LCCs) and cigarettes, defined as: (a) report smoking cigarettes on ≥ 8 of the past 30 days, and (b) report smoking unaltered LCCs (without marijuana) on ≥ 8 of the past 30 days.

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.

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.
