Cannabis use is prevalent among youth with mental illness, despite the increased risk of exacerbating psychiatric symptoms. The rapidly changing legality of cannabis has contributed to its normalization and decreased perceived risks. This study qualitatively gathered young adult psychiatric patients’ (n=15) perspectives on cannabis to inform a use reduction intervention. NVivo12 was used to organize coded data and facilitate analysis. Motivations to use included viewing cannabis utilization as normalized, supported, and a safer alternative to psychiatric medications. Facilitators for decreasing use were cannabis’ inadequacy at long-term symptom relief, the negative psychiatric sequelae seen in other users, and moderation of intake. Recommendations for the intervention included avoiding overly critical content and providing behavioral skills to aid reduction while improving psychiatric symptoms. Young adults in psychiatric care have unique motivations for cannabis consumption and decreasing use, which should be targeted in future interventions.

尽管加剧精神症状的风险增加，但大麻的使用在患有精神疾病的青少年中很普遍。大麻合法性的快速变化有助于其正常化并降低感知风险。这项研究定性地收集了年轻成年精神病患者的（n=15）关于大麻的观点为减少使用干预提供信息。NVivo12 用于组织编码数据并促进分析。使用的动机包括将大麻的使用视为正常化、支持和更安全的精神药物替代品。减少使用的促进因素是大麻在长期症状缓解方面的不足、在其他使用者身上看到的负面精神后遗症以及摄入量适度。对干预的建议包括避免过于批评的内容和提供行为技巧以帮助减少，同时改善精神症状。接受精神科治疗的年轻成年人对吸食大麻和减少吸食大麻有着独特的动机，这应该是未来干预措施的目标。
