Project Summary An estimated 1.5 million U.S. young adults are dual users of cannabis and tobacco. Dual users experience higher rates of dependence and difficulty quitting, compounding their risk of long- term health problems and posing a unique public health challenge. Drive to obtain and use substances despite cost is a centerpiece of addiction. Overvaluation of substances is captured by the concept behavioral economic demand (referred to hereafter as demand). Progress in preventing and treating dual use among young adults requires studying demand for cannabis and tobacco in three key areas. First, it is essential to characterize demand for cannabis and tobacco among users of both substances and understand how demand for each substance changes over time (Aim 1). Second, critical gaps in our understanding of dual use include not knowing how the link between demand and substance-specific outcomes, such as dependence and quit attempts operates among dual users, and whether demand for one substance impacts outcomes for the co-used substance (Aim 2). Third, the lack of a theory-based, explanatory model connecting demand to dual use is a barrier to progress in prevention and treatment of dual use. Social cognitive theory (SCT) is a widely used behavioral health model for understanding substance use, containing modifiable factors such as expectancies, perceptions of risk and social acceptability, and identity, which has yet to be applied to dual use of cannabis and tobacco. This study will identify SCT factors linked with demand and dual use (Aim 3), providing actionable targets of intervention. Addressing these aims will create significant progress in preventing and treating a unique public health problem among a high-risk group, consistent with NIDA’s mission. A prospective, cohort design will be used to measure behavioral economic demand for tobacco and cannabis, current use of tobacco and cannabis and related behavioral health effects, and SCT factors among 250 young adults (age 18-25) current tobacco and cannabis users in San Diego, CA at three, 75-minute visits: baseline, month 6, and month 12. The study will be conducted by an experienced university research lab in San Diego, CA with a track record of recruiting and retaining tobacco and cannabis users, in collaboration with an expert in behavioral economic demand measurement and a leading biostatistician. This project will provide students a high-quality research experience in the execution, analysis, and reporting of the study, consistent with the R16 aim.

项目概要 据估计，有 150 万美国年轻人同时吸食大麻和烟草。双用户 经历更高的依赖率和戒烟困难，增加了他们长期依赖的风险 长期健康问题并构成独特的公共卫生挑战。驱动获取和使用 尽管价格昂贵，但物质是成瘾的核心。捕捉到物质的高估 行为经济需求（以下简称需求）的概念。进展情况 预防和治疗年轻人的双重使用需要研究大麻的需求 和烟草三个关键领域。首先，必须确定对大麻的需求特征 两种物质使用者中的烟草，并了解对每种物质的需求如何 随着时间的推移而变化（目标 1）。其次，我们对双重用途理解的关键差距包括： 了解需求与特定物质结果（例如依赖性）之间的联系 和戒烟尝试在双重使用者之间进行，以及对一种物质的需求是否会影响 共同使用物质的结果（目标 2）。三是缺乏理论基础、解释依据。 将需求与双重用途联系起来的模型是预防和治疗进展的障碍 双重用途。社会认知理论（SCT）是一种广泛使用的行为健康模型 了解物质使用，包含可改变的因素，例如期望、看法 风险和社会可接受性以及身份，尚未应用于大麻的双重使用 和烟草。本研究将确定与需求和双重用途相关的 SCT 因素（目标 3）， 提供可行的干预目标。实现这些目标将创造重大成果 在预防和治疗高危人群中独特的公共卫生问题方面取得的进展， 与 NIDA 的使命一致。前瞻性队列设计将用于衡量行为 对烟草和大麻的经济需求、烟草和大麻的当前使用及相关 250 名年轻人（18-25 岁）当前吸烟的行为健康影响和 SCT 因素 加利福尼亚州圣地亚哥的大麻使用者进行了 3 次每次 75 分钟的访问：基线、第 6 个月和第 1 个月 12. 该研究将由加利福尼亚州圣地亚哥一所经验丰富的大学研究实验室进行 与以下机构合作，在招募和留住烟草和大麻使用者方面有着良好的记录 行为经济需求测量专家和领先的生物统计学家。这 项目将为学生提供执行、分析和研究方面的高质量研究经验 研究报告，与 R16 目标一致。
