BACKGROUND
Approximately 1 in 6 cannabis users develop a cannabis use disorder (CUD) and the odds increase to 1 in 2 for daily users.
OBJECTIVE
The Dual use of Cannabis and Tobacco Monitoreing through a Gamified Web app (DuCATA_GAM-CaT) project aims to identify cannabis-tobacco patterns of use and withdrawal symptoms among individuals with CUD who are attending substance abuse programs.
METHODS
The project uses a mixed methods approach consisting of 3 studies. First, a participatory qualitative study involves focus groups comprising individuals with CUD, clinicians, project researchers, and an expert gamification company to co-design a gamified web app. Second, a longitudinal prospective study to follow up individuals over 6 weeks with CUD attending substance abuse programs . Participants report their cannabis-tobacco usage patterns, type and frequency of tobacco use, nicotine dependence, withdrawal symptoms, psychoemotional factors, and motivation to quit both substances. Predictive analysis techniques are used to analyze clinical, demographic, psychological, and environmental data to predict the probability of achieving abstinence. Third, homogeneous focus groups to explore participants' experiences during their CUD treatment.
RESULTS
By June 2024, the project had completed the first study, defining eligible cannabis user profiles, developed the initial web app prototype, and initiated recruitment across 10 centers, with 74 participants enrolled, aiming to reach 150 participants in total.
CONCLUSIONS
All participants are required to provide informed consent, and their information is kept confidential and anonymized following confidentiality rules. The research team is committed to disseminating the results obtained to professional and patient groups, as well as informing public health agents, to positively influence political and social decision makers and design programmers. Additionally, we aim to prioritize the publication of the results in high-impact journals specialized in drug abuse, public health, and health care services research.

背景
大约每 6 个大麻使用者中就有 1 个会出现大麻使用障碍（CUD），而每日使用者的这一比例上升至 1 比 2。
目的
通过一款游戏化网络应用程序（DuCATA_GAM-CaT）监测大麻和烟草双重使用的项目旨在识别参加药物滥用项目的 CUD 个体的大麻-烟草使用模式和戒断症状。
方法
该项目采用混合方法，包括 3 项研究。首先，一项参与式定性研究包括由 CUD 个体、临床医生、项目研究人员和一家专业游戏化公司组成的焦点小组，共同设计一款游戏化网络应用程序。其次，一项对参加药物滥用项目的 CUD 个体进行为期 6 周随访的纵向前瞻性研究。参与者报告他们的大麻-烟草使用模式、烟草使用的类型和频率、尼古丁依赖程度、戒断症状、心理情绪因素以及戒除这两种物质的动机。使用预测分析技术分析临床、人口统计学、心理学和环境数据，以预测达到戒断的可能性。第三，进行同质焦点小组讨论，以探索参与者在 CUD 治疗期间的体验。
结果
截至 2024 年 6 月，该项目已完成第一项研究，确定了合格的大麻使用者特征，开发了初始网络应用程序原型，并在 10 个中心启动了招募工作，已有 74 名参与者入组，目标是总共招募 150 名参与者。
结论
所有参与者都需要提供知情同意，并且他们的信息将按照保密规则进行保密和匿名处理。研究团队致力于向专业和患者群体传播获得的结果，并向公共卫生机构报告，以积极影响政治和社会决策者并设计项目。此外，我们还旨在优先在专门研究药物滥用、公共卫生和医疗保健服务研究的高影响力期刊上发表结果。
