This clinical trial will recruit young adults who currently use cigarillos and examine the smoking behavior and perceptions of different flavored cigarillos, product ingredients/additives impacting these perceptions, and simulated tobacco use outcomes (quitting, switching) in various policy scenarios where different types of flavors are available on the market.

This clinical trial will isolate the unique effects of concept descriptors on increased cigarillo use and appeal among experienced young adult cigarillo users. The study will seek to determine the addiction potential of concept flavored cigarillos by examining associations of cigarillo flavor type (concept, characterizing, tobacco) and cigarillo flavoring additives/ingredients to complementary measures of product appeal: subjective effects (e.g., satisfaction, reward, taste), actual smoking behavior (e.g., number of puffs), and simulated cigarillo purchasing, other tobacco product substitution, or quitting under different flavor ban scenarios via an Experimental Tobacco Marketplace (ETM).
