Alongside the rise of emerging adulthood, policy contexts for marijuana have rapidly changed, with increases in availability and the number of daily users. We identify heterogeneous pathways of marijuana use from age 16 to 26, and examine how these pathways differentiate adult role transitions by age 28. Latent class analyses identified five trajectories: abstainers, dabblers, consistent users, early heavy quitters, and persistent heavy users. Dabblers are no different from abstainers on educational and labor market outcomes, and both have higher odds of adult role transitions relative to heavier use classes. Dabblers differ from abstainers on certain family transitions, yet remain distinct from the heavier use classes. Besides parenthood, early heavy quitters and persistent heavy users are similar, suggesting that heavy use is particularly detrimental early during transitions to adulthood. Distinct trajectories of marijuana use may differentiate young people into divergent pathways of transitions to adulthood, which may have long-term implications.
随着新兴成年期的兴起，大麻的政策环境迅速变化，其可得性和每日使用者数量都有所增加。我们确定了16岁至26岁期间大麻使用的不同路径，并研究这些路径如何在28岁时区分成人角色转变。潜在类别分析确定了五种轨迹：戒除者、涉猎者、持续使用者、早期重度戒除者和持续重度使用者。涉猎者在教育和劳动力市场结果方面与戒除者没有差异，并且相对于使用量更大的类别，两者在成人角色转变方面都有更高的几率。涉猎者在某些家庭转变方面与戒除者不同，但与使用量更大的类别仍有区别。除了为人父母之外，早期重度戒除者和持续重度使用者相似，这表明在向成年期过渡的早期，大量使用大麻尤其有害。大麻使用的不同轨迹可能会将年轻人分化为不同的成年过渡路径，这可能会产生长期影响。
