Tobacco and other substance co-use among adolescents and young adults with cancer who use tobacco: prevalence and associations with nicotine dependence and depression.

ABSTRACT:

Introduction

Tobacco and other substance co-use has not been examined in adolescent and young adult (AYA) cancer survivors. We compared the prevalence of past-month co-use of tobacco+cannabis, alcohol and illicit drugs between AYAs with and without a cancer history and considered associations between co-use and nicotine dependence in AYA cancer survivors who use tobacco, exploring if past-year major depression moderates this relationship.

Methods

2015-2019 National Survey on Drug Use and Health data were used to analyse past-month co-use in 7793 AYAs (228 with cancer; 7565 without cancer). Weighted univariable and multivariable logistic regression models estimated associations between cancer history and co-use and co-use with nicotine dependence (among AYA cancer survivors)
