Nonmedical (recreational) cannabis use is now legal in many states. Additional states are considering legalization, despite the weakness of the current evidence base regarding potential impacts on public health. This R01 proposal seeks 5 years of funding to understand: Aim 1) changes in cannabis use across the first decade following cannabis legalization; Aim 2) changes in alcohol use, nicotine use, and their co-use with cannabis following cannabis legalization; and Aim 3) whether psychosocial consequences of cannabis use change in a legal cannabis context. This knowledge is critical to inform policy, support efforts to maintain hard- won reductions in teen cannabis use since the 2000s, and promote responsible use by adults. The proposed project is grounded in life course theories of development and substance use, and uniquely suited to address stated goals. It continues and expands upon the Seattle Social Development Project-The Intergenerational Project (SSDP-TIP), which aims to understand the impact of cannabis legalization on youth and parent cannabis and other drug use (n = 426 families, 80% living in Washington State). SSDP-TIP includes a parent drawn from another ongoing longitudinal panel study that began in 1985, their oldest biological child, and a second caregiver (usually the spouse) when available. Seven waves of pre-legalization data (2002-2011; mean child age in 2011 = 12) and three waves of short-term post-legalization data (2015-2017; mean child age in 2017 = 18) from offspring and parents are available. The proposed study will add three additional annual data collections post-legalization in 2022, 2023, and 2024 with parents and offspring (mean offspring age in 2024 = 25; range: 11-36 years). For adolescent offspring, the accelerated longitudinal design allows us to compare offspring measured before legalization to offspring from later birth cohorts measured at the same ages, but after legalization. This permits the disentangling of child age and policy effects, and facilitates understanding of the implications of cannabis legalization for prevention in ways that other studies cannot. The inclusion of young adult offspring allows examination of the impact of cannabis legalization on patterns of use and consequences across the 20s and into the early 30s. The inclusion of parents permits examination of post- legalization changes in cannabis and other drug use and consequences across the 40s. SSDP-TIP is the only study in Washington State with longitudinal data from youth and their parents beginning 10 years before legalization. With the proposed data collections, it will also stretch to 12 years post-legalization. This prospective, longitudinal design provides important advantages over large, repeated cross sectional studies by enabling causal ordering of legalization and changes in behavior, disentanglement of change due to legalization versus time or age, and study of both within- and between-person change. Findings will inform the timing of efforts to prevent underage and problematic cannabis, tobacco, and alcohol use and help to clarify public health impacts in the context of cannabis legalization.

现在，在许多州，非医学（娱乐）大麻的使用是合法的。其他州正在考虑 合法化，尽管目前的证据基础较弱关于对公共卫生的潜在影响。 该R01提案寻求5年的资金来理解：目标1）大麻使用的变化 大麻合法化后的十年；目标2）使用酒精使用，尼古丁使用及其共同使用 大麻合法化后的大麻；目标3）大麻使用的社会心理后果是否 在法律大麻的情况下改变。这些知识对于为政策提供信息至关重要，支持维持艰苦的努力 - 自2000年代以来，赢得了青少年大麻使用的减少，并促进了成年人的负责使用。提议 项目基于生命课程的发展和物质使用理论，并且非常适合解决 陈述目标。它继续并扩展了西雅图社会发展项目 - 代际 项目（SSDP-TIP），旨在了解大麻合法化对青年和父母的影响 大麻和其他药物使用（n = 426个家庭，居住在华盛顿州80％）。 SSDP-TIP包括父母 从1985年开始的另一项正在进行的纵向小组研究中得出，他们最古老的亲生孩子和一个 第二个护理人员（通常是配偶）。七波冠军前数据波（2002-2011；平均值 2011年的儿童年龄= 12）和三波短期后的冠生后数据（2015-2017；平均儿童年龄 2017年= 18）来自后代和父母。拟议的研究将添加三个其他年度数据 在2022年，2023年和2024年的合法化后收集与父母和后代（2024年的平均后代年龄= 25;范围：11 - 36年）。对于青少年后代，加速的纵向设计使我们能够比较 从同一年龄衡量的后期同龄人合法化之前，在合法化之前测量的后代，但 合法化后。这允许解散儿童年龄和政策影响，并有助于理解 大麻合法化对预防的含义，以其他研究无法进行。包括 年轻的成人后代允许检查大麻合法化对使用方式和 在20年代和30年代初期的后果。包括父母允许检查后检查 40年代的大麻和其他药物使用以及后果的合法化变化。 SSDP-TIP是唯一的 在华盛顿州学习青年及其父母的纵向数据。 合法化。随着拟议的数据收集，它也将在法律化后12年延长。这 前瞻性，纵向设计通过 实现合法化和行为变化的因果秩序，由于 合法化与时间或年龄，以及对人之间变化的研究。调查结果将告知 防止未成年和有问题的大麻，烟草和饮酒的努力的时机，并有助于澄清 公共卫生在大麻合法化的背景下影响。
