Cannabis use is a frequent problem among people with psychotic disorders that has been related to a worse prognosis. Understanding the reasons of cannabis use may help to develop comprehensive treatments and, as a result, improve the psychosis course.
A systematic review of studies published in English and Spanish language from 1990 until March 2012 describing reasons for and subjective effects of cannabis use in patients with psychosis were reviewed. However, only those studies in which cannabis use was one of the three main substances studied were included.
Initially, 73 studies, of which 12 met the inclusion criteria, were identified. Most of the studies include heterogeneous patients, at different illness stages, and a few studies included a non-psychotic comparison group. The most common reasons for cannabis use were those related with social activities, mood disturbance, relaxation and getting high.
The most common reasons for cannabis use in patients with psychosis were related with social activities, mood disturbances, relaxation and getting high. However, a more homogeneous methodology need to be established, including different illness stages, to facilitate the interventions to reduce cannabis use in all phases of psychotic disorders development.
大麻使用在患有精神障碍的人群中是一个常见问题，且与较差的预后相关。了解大麻使用的原因可能有助于制定综合治疗方法，从而改善精神病病程。
对1990年至2012年3月期间以英文和西班牙文发表的研究进行系统综述，这些研究描述了精神病患者使用大麻的原因和主观影响。然而，仅纳入那些将大麻使用作为所研究的三种主要物质之一的研究。
最初识别出73项研究，其中12项符合纳入标准。大多数研究纳入了处于不同疾病阶段的异质性患者，少数研究纳入了非精神病对照组。大麻使用最常见的原因与社交活动、情绪障碍、放松和兴奋有关。
