About this study

Official title: 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Demand Elasticity

    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.

    Measured: Post-treatment (after being assigned to use it for 7 days)

  2. Demand Intensity

    Hypothetical consumption when free. These are the model-adjusted predicted mean values of intensity, adjusted for covariates.

    Measured: Post-treatment (after 7 days of being assigned to condition)
