Schizotypy and its associated features—negative schizotypy, disorganization, and positive schizotypy—are correlated with increased cannabis use. Yet, it is unclear whether cannabis users with schizotypy are at greater risk of developing cannabis problems. Individuals with elevated schizotypy may be particularly vulnerable to cannabis problems. It is important to understand this association given the unknown harms of chronic cannabis use. Data for these analyses were drawn from a larger investigation of cannabis use in adult romantic relationships. Participants were community adults (N = 366; M Age = 24.6, SD = 3.1) who reported regular use of cannabis. Participants completed baseline surveys measuring cannabis use frequency, problems, and schizotypy. Follow-up assessments of cannabis problems and frequency were completed 4-, 7- and 10-months post-baseline. Multiple regression was used to test the effect of schizotypy—measured using the Schizotypal Personality Questionnaire-Brief (SPQ-B, Raine & Benishay, 1995)—on cannabis use problems controlling for 30-day cannabis use. At baseline, disorganization and positive schizotypy were associated with cannabis use, primarily for women. Results revealed that with cannabis use frequency in the model, the Disorganization subscale of the SPQ-B predicted cannabis problems at baseline and all 3 follow-up assessments. Results are consistent with research suggesting that those exhibiting odd behaviors report more problematic cannabis use. Future research may further this line of inquiry with a focus on longitudinal, reciprocal relationships among schizotypy features, cannabis use, and cannabis problems.

精神分裂症及其相关特征（阴性精神分裂症，混乱和阳性精神分裂症）与大麻使用量增加相关。然而，尚不清楚具有精神分裂症的大麻使用者是否更有可能出现大麻问题。精神分裂症患者可能特别容易受到大麻问题的侵害。鉴于长期使用大麻的危害未知，了解这种联系非常重要。这些分析的数据来自对成人恋爱关系中大麻使用的较大调查。参加者为社区成人（N = 366；M年龄= 24.6，SD = 3.1）报告经常使用大麻的人。参加者完成了对大麻使用频率，问题和精神分裂症的基线调查。基线后4、7和10个月完成了对大麻问题和大麻发生频率的后续评估。多元回归用于检验精神分裂症的影响（使用精神分裂症人格问卷调查（SPQ-B，Raine＆Benishay，1995））对控制30天大麻使用的大麻使用问题的影响。在基线时，杂乱无章和精神分裂症阳性与使用大麻有关，主要是女性。结果显示，在模型中使用大麻的频率下，SPQ-B的Disorganization分量表在基线和所有3次随访评估中预测了大麻问题。结果与研究一致，表明那些表现出奇怪行为的人报告使用大麻的问题更大。未来的研究可能会进一步研究这一问题，重点是精神分裂症特征，大麻使用和大麻问题之间的纵向，相互关系。
