In recent decades, European countries have seen a substantial increase in home cultivation of cannabis. In France, the prevalence of cannabis use continues to increase despite its possession, sale, and cultivation being strictly illegal. The present study aimed to describe the profile and motivations of people in France who cultivate cannabis at home. We separately analyzed data from two convenience samples of people who use cannabis daily in France, based on two online cross-sectional surveys. In the first analysis (N = 3840), we used a multivariable logistic regression model to assess factors associated with home cultivation as the main source of cannabis supply. In the second analysis (N = 574), we described participants' motivations for home cultivation and their cultivation patterns. In the two samples, 11% and 16% reported home cultivation as their main source of supply, respectively. Age, male gender, stable housing, living with a partner, consuming cannabis in herbal form, smoking joints with little or no tobacco, smoking cannabis from a bong or pipe, non-smoking modes of cannabis administration, and using cannabis exclusively for therapeutic reasons were all positively associated with home cultivation, while urban area of residence and at-risk alcohol use were negatively associated. The main reason reported for home cultivation was to manage quality. Few reported selling some of their crop, and most were self-sufficient. Finally, we interpret this practice as a personal response to cannabis prohibition and the unregulated market. Accordingly, possible harm reduction strategies are discussed.
近几十年来，欧洲国家家庭种植大麻的现象大幅增加。在法国，尽管持有、销售和种植大麻均属严格违法，但大麻使用的流行率仍在持续上升。本研究旨在描述法国在家中种植大麻的人群的特征和动机。我们基于两项在线横断面调查，分别分析了法国每日使用大麻人群的两个便利样本的数据。在首次分析（N = 3840）中，我们使用多变量逻辑回归模型来评估与作为大麻供应主要来源的家庭种植相关的因素。在第二次分析（N = 574）中，我们描述了参与者家庭种植的动机及其种植模式。在这两个样本中，分别有11%和16%的人报告家庭种植是其主要供应来源。年龄、男性、稳定住房、与伴侣同住、以草药形式消费大麻、吸食不含或仅含少量烟草的大麻烟、使用水烟筒或烟斗吸食大麻、非吸烟方式的大麻给药以及仅出于治疗目的使用大麻均与家庭种植呈正相关，而居住在城市地区和有酗酒风险则呈负相关。报告的家庭种植主要原因是控制质量。很少有人报告出售部分作物，大多数人自给自足。最后，我们将这种行为解释为对大麻禁令和不受监管市场的个人反应。据此，讨论了可能的减少危害策略。
