There is increasing evidence that cannabidiol (CBD) use is associated with clinically significant liver enzyme (LE) elevations and drug-induced liver injury (DILI). The proportion of LE elevations and DILI events reported in the literature meet the Council for International Organizations of Medical Sciences' (CIOMS) classification of a common adverse drug reaction. However, these potential adverse events are unknown to many clinicians and may be overlooked.

Cannabis vaporization is useful for individuals requiring fast-acting method of cannabis administration and for individuals using smoked cannabis as a harm reduction tool. There is a need for guidance on how to assess if a patient is a vaporization candidate and how to safely initiate and monitor cannabis vaporization. An overview of safe cannabis vaporization, including practical guidance and tactics to promote the lowest-risk use, is provided.

Issues: Vaporisation is a common method of cannabis administration. Inconsistent terminology and jargon regarding vaporisation has led to confusion. The increasing public interest and access to cannabis, combined with possible safety concerns associated with certain cannabis vaping products, warrants improved consumer and public and health care professional knowledge.

Emerging evidence on substituting cannabis for more harmful drugs has led to cannabis becoming a novel harm-reduction strategy for combating the current drug poisoning crisis. However, the authorization of medical cannabis as part of a harm-reduction approach and recovery strategy has significant implementation barriers rooted in longstanding stigma towards cannabis. Through a multi-discipline collaboration of Canadian clinicians and academic researchers, we highlighted stigma barriers and opportunities to address these barriers to elicit improved delivery of medical cannabis as a harm-reduction therapy within existing therapeutic frameworks.

Article Synopsis
  • Measurement-based care (MBC) uses patient-reported symptom measurements to guide treatment, improving outcomes in outpatient psychiatry, but it's rarely implemented.
  • A quality improvement project aimed to increase the completion of MBC symptom scales to 75% in a Toronto psychiatric clinic, and used methods like stakeholder interviews to navigate challenges.
  • The initiative saw an increase in completion rates from 10.8% to 57.1%, with clinician support identified as crucial for success, while barriers included physician attitudes and administrative load.

Objective: The drug poisoning crisis throughout North America necessitates novel harm reduction approaches. Emerging evidence suggests that cannabidiol (CBD) may have some utility as a harm reduction modality for those with problematic substance use. This rapid review aimed to synthesize available evidence on CBD as a potential harm reduction tool for people who use drugs while providing clinical and research insights.

The interest in psilocybin as a therapeutic approach has grown exponentially in recent years. Despite increasing access, there remains a lack of practical guidance on the topic for health care professionals. This is particularly concerning given the medical complexity and vulnerable nature of patients for whom psilocybin-assisted psychotherapy may be considered.

Background: With the recent legalization of cannabis for medical purposes in many countries, there has been an increased number of individuals using such products. While there is considerable evidence indicating that cannabis may have therapeutic effects for a range of different conditions, concerns remain about the risk of developing cannabis use disorders for those at risk, or patients without appropriate clinical guidance. The aim of the present study was to determine the prevalence of problematic cannabis use in a cohort of cannabis users who consumed the drug for medical purposes and to identify potential risk factors.

Smoking cannabis in medical users is associated with exposure to harmful toxins. It is important to characterize cannabis-use profiles and risk-factors for medical cannabis users who smoke cannabis. 100 members of a medical cannabis dispensary with mental health concerns were interviewed in detail about their cannabis use.

Clinicians play an important role in promoting safe and responsible medical cannabis use. One essential component to safe use is considering a patient's risk of neurocognitive impairment. However, there remains a lack of practical guidance on how clinicians can evaluate this risk for medical cannabis patients.

Increase in medical cannabis use, along with available products, warrants the need for clinicians to be knowledgeable in evaluating the quality of any cannabis product presented in clinical practice. Determining whether a product is regulated within the region is key in assessing overall quality and safety. Regulated products are held to a higher standard including independent testing, contamination mitigation, and concentration limits.

Medical cannabis use is increasing worldwide. Clinicians are commonly asked by patients to provide guidance on its safety and efficacy. Although there has been an increase in research on the role of medical cannabis for a number of different conditions, we found that there was a paucity of clear safety guidance on its use.

While the recreational use of cannabis has well-established dose-dependent effects on neurocognitive and psychomotor functioning, there is little consensus on the degree and duration of impairment typically seen with medical marijuana use. Compared to recreational cannabis users, medical cannabis patients have distinct characteristics that may modify the presence and extent of impairment. The goal of this review was to determine the duration of acute neurocognitive impairment associated with medical cannabis use, and to identify differences between medical cannabis patients and recreational users.
