Dr. Zorba Paster emphasizes the need for greater awareness of cannabis use disorder, particularly as daily cannabis consumption becomes more common in society. A recent study published in JAMA Psychiatry highlights the potential mental health risks associated with excessive cannabis use, including a connection to psychosis.
Cannabis use disorder is defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as the presence of clinically significant impairment or distress within a 12-month period, indicated by at least two specific criteria. These include using cannabis in greater amounts than intended, unsuccessful attempts to cut down, excessive time spent on cannabis-related activities, cravings, neglect of social obligations, and continued use despite physical or psychological problems.
Dr. Paster shares a personal reflection on cannabis use, recalling his experiences in the 1960s alongside friends who preferred marijuana over alcohol. However, he notes the striking difference in societal perceptions. While alcohol-related issues such as alcoholism are widely recognized and stigmatized, cannabis use disorder lacks the same level of acknowledgment, which can hinder treatment and prevention efforts.
The recent JAMA article explores how cannabis interacts with the brain’s dopamine system. Dopamine, often referred to as the ‘feel-good’ hormone, is released during pleasurable activities. However, cannabis can artificially elevate dopamine levels, making withdrawal difficult. This spike can lead to altered perceptions, delusions, and paranoia, characteristics of psychosis.
Researchers using MRI scanners found that individuals with cannabis use disorder exhibited brain activity patterns similar to those seen in stress-induced psychosis. This research underlines the need for clinicians and the public to recognize the potential dangers of frequent cannabis use, particularly as legalization spreads.
Dr. Paster argues that as cannabis becomes more accessible, society must approach it with the same caution as alcohol. He advocates for increased education on the risks of daily use, particularly for vulnerable populations. The conversation surrounding cannabis needs to evolve, moving past outdated stigmas to develop a more informed and respectful understanding of its potential impact on health.
As cannabis use continues to rise, it is crucial to remember the importance of moderation and awareness. Dr. Paster urges individuals to consider the implications of their consumption, advocating for responsible use and open discussions about cannabis and its effects on mental health.
