Assessing cannabis consumption remains complex due to no reliable registration systems. We tested the likelihood of establishing a Standard Joint Unit (SJU) which considers the main cannabinoids with implication on health through a naturalistic approach. Methodology. Pilot study with current cannabis users of four areas of Barcelona: universities, nightclubs, out-patient mental health service, and cannabis associations. We designed and administered a questionnaire on cannabis use-patterns and determined the willingness to donate a joint for analysis. Descriptive statistics were used to analyze the data.
Forty volunteers answered the questionnaire (response rate 95%); most of them were men (72.5%) and young adults (median age 24.5 years; IQR 8.75 years) who consume daily or nearly daily (70%). Most participants consume marihuana (85%) and roll their joints with a median of 0.25 gr of marihuana. Two out of three (67.5%) stated they were willing to donate a joint.
Obtaining an SJU with the planned methodology has proved to be feasible. Pre-testing resulted in an improvement of the questionnaire and retribution to incentivize donations. Establishing an SJU is essential to improve our knowledge on cannabis-related outcomes.
由于没有可靠的登记系统，评估大麻消费仍然很复杂。我们通过自然主义的方法测试了建立一个考虑到主要大麻素并对健康有影响的标准大麻卷单位（SJU）的可能性。
对巴塞罗那四个地区（大学、夜总会、门诊心理健康服务和大麻协会）的当前大麻使用者进行试点研究。我们设计并管理了一份关于大麻使用模式的问卷，并确定了捐赠大麻卷进行分析的意愿。使用描述性统计来分析数据。
40 名志愿者回答了问卷（回应率 95%）；他们大多数是男性（72.5%）和年轻人（中位数年龄 24.5 岁；IQR 8.75 岁），他们每天或几乎每天（70%）吸食大麻。大多数参与者吸食大麻（85%），他们用大麻卷的中位数为 0.25 克。三分之二（67.5%）的人表示愿意捐赠大麻卷。
按照计划的方法获得 SJU 已被证明是可行的。预测试改进了问卷，并提供回报以激励捐赠。建立 SJU 对于提高我们对大麻相关结果的认识至关重要。
