To investigate the influence of the family socioeconomic status (F-SES) on various intensities and frequencies of cannabis use in late adolescence.
DESIGN/SETTINGS/PARTICIPANTS: Data were obtained from a cross-sectional survey conducted in 2008, which was representative of French youth aged 17(n = 39,542). Outcomes were overall use (abstinence, lifetime use, 1-9, and 10+ uses in the past year) for all adolescents, and frequent use for those who smoked cannabis at least 10 times in the past year (≤9, 10-19, 20+ uses in the past month). Additionally, cannabis use disorders and heavy use (having smoked at least 4 joints last time) were studied among previous-year users. F-SES was the highest occupational category of both parents (in 7 categories, from managers/professionals [used as the reference category] to inactive/unemployed). Multinomial logistic regressions were computed controlling for gender; other substances use; parental separation; parental use of alcohol, tobacco, and cannabis; housing, being out of school, and sociability.
For overall use, we found a strong positive social gradient: the lower the F-SES or the higher the frequency of use, the lower the odds ratio (OR) (from .85 to .52 for 10+ uses in the past year among farmers). For frequent use, we found a strong negative gradient: the lower the F-SES category, the higher the OR (from 1.02 to 2.05 among inactive/unemployed), and likewise for cannabis use disorder and heavy use (OR = 1.85 and 2.03 among inactive/unemployed).
Adolescents from affluent families are more prone to experimentation with cannabis and to use it at low levels but present lower levels of frequent, heavy, or problematic use than those from other SES categories. Mechanisms that hinder transition to intensive use should be investigated.
研究家庭社会经济地位（F-SES）对青少年晚期各种大麻使用强度和频率的影响。
设计/设置/参与者：数据来自于 2008 年进行的一项横断面调查，该调查代表了法国 17 岁青少年（n=39542）。结果是所有青少年的总体使用情况（禁欲、终生使用、过去一年中使用 1-9 次和 10+次），以及过去一年至少使用大麻 10 次的青少年的频繁使用情况（≤9 次、10-19 次、20+次）。此外，还研究了过去一年使用者中的大麻使用障碍和重度使用（上次吸烟至少 4 个烟卷）。F-SES 是父母双方最高的职业类别（分为 7 类，从经理/专业人员[用作参考类别]到不活跃/失业）。控制性别、其他物质使用、父母离异、父母使用酒精、烟草和大麻、住房、失学和社交性，进行多项逻辑回归。
对于总体使用情况，我们发现了一个很强的正社会梯度：F-SES 越低或使用频率越高，比值比（OR）越低（从过去一年中使用 10+次的农民的 0.85 到 0.52）。对于频繁使用，我们发现了一个很强的负梯度：F-SES 类别越低，OR 越高（从不活跃/失业的 1.02 到 2.05），大麻使用障碍和重度使用也是如此（OR=1.85 和 2.03，从不活跃/失业）。
来自富裕家庭的青少年更容易尝试大麻，使用量也较低，但与其他 SES 类别相比，他们的频繁、重度或有问题的使用水平较低。应研究阻碍向密集使用过渡的机制。
