Addictive Potential of LCCs in Dual Users

UConn Health72 enrolled

Overview

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.

Outcomes

Primary Outcomes

Demand elasticity for preferred flavor LCCs

It is measured by the Cigarette Purchase Task, which will be adapted to assess this product. It is the hypothetical consumption of preferred flavor LCCs as increasing prices on a log-log scale.

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

Demand elasticity for unflavored LCCs

It is measured by the Cigarette Purchase Task, which will be adapted to assess this product. It is the hypothetical consumption of unflavored LCCs as increasing prices on a log-log scale.
