目的：确定将大麻使用者分为不同类型是否有助于澄清大麻功效与消费行为、有害身体影响和心理依赖性之间的关系。方法：招募了 388 名在过去一个月至少吸过一次大麻的受访者作为现场样本。我们在荷兰五个城市的 28 家大麻咖啡店对他们进行了联系和采访。通过辅助自我完成问卷收集数据。使用 k 均值方法进行聚类分析。 结果：观察到自然环境中的大麻使用者以各种方式调整其摄入量以适应药物的效力。聚类分析确定了三大类大麻使用者。最强的高类型是最年轻的，每月消耗的剂量最高，吸入效力更高的大麻更深，并且心理大麻依赖得分最高。一贯的高类型更喜欢温和的大麻，每月消耗的剂量最低，并通过减少吸入深度和减少吸烟来补偿更强的大麻。稳定量类型是最古老的，通常单独吸烟，每月消耗中间剂量，并且不倾向于根据大麻的效力调整吸入深度。结果表明，这种类型也可能反映了持续吸食大麻的职业生涯中的三个连续阶段。结论：评估较高 THC 浓度对大麻外部和内部暴露影响的实验室研究应该考虑到所研究的吸食者类型可能影响结果的可能性。 (c) 2006 Elsevier B.V. 保留所有权利。
Aims: To determine whether a classification of cannabis users into different types can help to clarify the relationship between cannabis potency and consumption behaviour, harmful physical effects and psychological dependency.Methods: A field sample of 388 respondents was recruited who had smoked cannabis at least once in the past month. They were contacted and interviewed in 28 cannabis coffeeshops located in five Dutch cities. Data were collected with an assisted self-completion questionnaire. Cluster analysis was performed using the k-means method.Findings: Various ways were observed in which cannabis users in natural settings adjusted their intake to the potency of the drug. Cluster analysis identified three broad types of cannabis users. The strongest high type was the youngest, consumed the highest monthly dose, inhaled higher-potency cannabis more deeply, and scored highest on psychological cannabis dependency. The consistent high type preferred milder cannabis, consumed the lowest monthly dose, and compensated for stronger cannabis by inhaling less deeply and smoking less. The steady quantity type was the oldest, usually smoked alone, consumed an intermediate monthly dose, and did not tend to adjust the depth of inhalation to the potency of the cannabis. The results suggest that this typology might also reflect three successive stages in the careers of continuing cannabis users.Conclusions: Laboratory studies to assess the effects of higher THC concentrations on external and internal exposure to cannabis should allow for the possibility that the types of users studied can affect the results.
