Background: Cannabis is one of the most commonly used substances in patients with a psychotic disorder and is associated with a higher risk of psychotic relapses. Identifying reasons for cannabis use and subjective effects in patients with psychotic disorders can provide insight into the functions of cannabis use, and this may lead to targeted interventions. Methods: A literature search of the PubMed and PsycINFO databases for articles published from 1985 till 2008 was carried out to review studies that examined self-reported reasons for cannabis use and self-reported effects of cannabis use in patients with psychotic disorders. Results: Only a few studies were found that specifically assessed reasons for and effects of cannabis use. Despite the heterogeneity in the study samples and methodology, patients commonly reported that their reasons for cannabis use were enhancement of positive affect, relief of dysphoria and social enhancement. Fewer patients reported reasons related to relief of psychotic symptoms or relief of side effects of medication. Frequently reported positive effects of cannabis were positive changes in affect and relaxation. A large proportion of patients reported that cannabis negatively affected positive symptoms. Conclusions: Patients suffering from psychotic disorder report using cannabis mainly for affect regulation and socialization, despite the awareness that cannabis has a negative effect on positive symptoms. In spite of the heterogeneity of the studies, the results turned out to be broadly comparable and support the external validity of this review to a broad range of cannabis-using patients with psychotic disorder.

“…The first study to make a comprehensive examination of subjective experiences of cannabis use and reasons for using the drug among a group of people with psychosis found that the primary reason given was related to neither positive or negative symptoms, nor obvious side-effects of medication (Schofield et al, 2006). Instead, the most frequently cited motivations were to reduce boredom, improve socialisation and alleviate a cluster of symptoms, the most common of which were inner unrest/agitation (47%) and difficulty sleeping (43%).…”

Cannabis use is more common among people with severe mental illness than in the general population. It has detrimental effects on the course of the illness, physical health and social life of users, as well as being a financial burden on health services. It is important to understand why some people with severe mental illness continue to use cannabis, despite experiencing its effects on their condition. This article reviews research on the scale of cannabis use by such patients, the effects on the course of their illness, possible reasons to explain why they use it, and how they can be assessed in clinical settings, as well as providing some assessment tools to measure various characteristics related to cannabis use.

“…Reasons like these give voice to those who use marijuana to selfmedicate their psychosis Schofield et al 2006). The correlation between psychosis and regular cannabis use is concerning enough (Os et al 2002;Ruiz-Veguilla et al 2013), but several reasons compound our alarm.…”

A Virtue Analysis of Recreational Marijuana Use

Several empirical studies suggest that recreational marijuana is popularly perceived as an essentially harmless rite of passage that ends as young people settle into their careers and their adult intimate relationships. Is this perception accurate? To answer this question, we evaluate the morality of recreational marijuana use from a virtue perspective guided by the theological synthesis of St. Thomas Aquinas. Since the medical data reveals that recreational marijuana use is detrimental to the well-being of the user, we conclude that it is a vicious activity, an instance of the vice of intoxication, and as such would be morally illicit. Lay summary: In contrast to its medical use, the recreational use of marijuana cannot be justified for at least three reasons. First, as scientists have amply documented, it harms the organic functioning of the human body. Second, it impedes our ability to reason and in so doing does harm to us. Finally, it has lasting detrimental effects on the user and his neighbor, even when it occurs in a casual setting. Intoxication is always contrary to the integral good of the person. Thus, the use of marijuana is never warranted even for good, non-medical reasons.
