Abstract
INTRODUCTION Some evidence suggests that cannabis may be a safer substitute for other drugs. Historically, sober living houses (SLHs) have been abstinence-based environments designed for individuals in recovery to live with others in recovery. However, the evolving legal landscape around cannabis use has left SLH operators and managers in a difficult position regarding policies related to cannabis use among residents. The primary aim of this study was to examine how cannabis use relates to alcohol use, other drug use, and related problems among SLH residents. METHODS Baseline (N = 557), 6-month (n = 462), and 12-month (n = 457) data came from SLH residents living in 48 houses in Los Angeles, CA from 2018 to 2021. Longitudinal generalized estimating equation models tested associations between any past six-month cannabis use and alcohol and non-cannabis drug outcomes: any use, number of days of use, and any alcohol- or drug-related problems. Final models adjusted for baseline age, sex, race-and-ethnicity, inpatient substance use treatment, and alcohol/drug use days, and time-varying 12-step attendance and percent of social network using drugs/alcohol heavily. RESULTS At baseline, 107 (19.2 %) residents reported cannabis use in the past six months. At 12 months, 80 (17.5 %) residents reported cannabis use in the past six months. Across all timepoints, any vs. no past six-month cannabis use was related to significantly (P < 0.05) higher odds of past-month alcohol use (OR = 3.85, 95 % CI: 2.65, 5.59); more drinking days in the past six months (IRR = 1.76, 95 % CI: 1.40, 2.21); higher odds of alcohol problems (OR = 2.74, 95 % CI: 1.99, 3.76); higher odds of past-month drug use (OR = 10.41, 95 % CI: 6.37, 17.00); more drug use days in the past six months (IRR = 1.86, 95 % CI: 1.40, 2.49); and higher odds of drug problems (OR = 14.99, 95 % CI: 9.91, 22.68). CONCLUSIONS During each assessment period, almost one-fifth of individuals residing in sample of California sober living houses report using cannabis in the past six months. Cannabis does not appear to work as a substitute for alcohol or other drugs in this population because cannabis use is related to increased risk of alcohol and other drug use and problems. SLH managers and operators should consider potential harm that could result from house policies that fail to address cannabis use.

Translating the lived experience of illicit drinkers into program guidance for cannabis substitution: Experiences from the Canadian Managed Alcohol Program Study. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 122:104244.

Abstract
A small but growing body of research has suggested the potential for cannabis substitution to support Managed Alcohol Program (MAP) service users to reduce acute and chronic alcohol-related harms. In 2022, researchers from the Canadian Managed Alcohol Program Study (CMAPS) noted a dearth of accessible, alcohol-specific educational resources to support service users and program staff to implement cannabis substitution pilots at several MAP sites in Canada. In this essay, we draw on over 10-years of collaboration between CMAPS, and organizations of people with lived experience (the Eastside Illicit Drinkers Group for Education (EIDGE) and SOLID Victoria) to describe our experiences co-creating cannabis education resources where none existed to support MAP sites interested in beginning to provide cannabis to participants. The research team relied on the unique lived experiences and informal cannabis-related harm reduction strategies described by EIDGE and SOLID members to create cannabis education resources that were accurate and relevant to MAP sites. EIDGE was familiar with creating peer-oriented educational resources and convened meetings and focus groups to engage peers. CMAPS research team members created standard cannabis unit equivalencies to support program delivery, and clinical advisors ensured that the stated risks and benefits of cannabis substitution, as well as tapering guidance for withdrawal management, were safe and feasible. The collaboration ultimately produced tailored client-facing and provider-facing resources. Our experience demonstrates that the lived expertise of drinkers can play an integral role in creating alcohol harm reduction informational materials, specifically those related to cannabis substitution, when combined with data from rigorous, community-based programs of research like CMAPS. We close by listing additional considerations for cannabis substitution program design for MAP settings emerging from this process of collaboration between illicit drinkers, service providers, clinicians, and researchers for consideration by other programs.

Associations Between Canada's Cannabis Legalization and Emergency Department Presentations for Transient Cannabis-Induced Psychosis and Schizophrenia Conditions: Ontario and Alberta, 2015-2019.

Abstract
OBJECTIVE Cannabis legalization in many jurisdictions worldwide has raised concerns that such legislation might increase the burden of transient and persistent psychotic illnesses in society. Our study aimed to address this issue. METHODS Drawing upon emergency department (ED) presentations aggregated across Alberta and Ontario, Canada records (April 1, 2015-December 31, 2019), we employed Seasonal Autoregressive Integrated Moving Average (SARIMA) models to assess associations between Canada's cannabis legalization (via the Cannabis Act implemented on October 17, 2018) and weekly ED presentation counts of the following ICD-10-CA-defined target series of cannabis-induced psychosis (F12.5; n = 5832) and schizophrenia and related conditions ("schizophrenia"; F20-F29; n = 211,661), as well as two comparison series of amphetamine-induced psychosis (F15.5; n = 10,829) and alcohol-induced psychosis (F10.5; n = 1,884). RESULTS ED presentations for cannabis-induced psychosis doubled between April 2015 and December 2019. However, across all four SARIMA models, there was no evidence of significant step-function effects associated with cannabis legalization on post-legalization weekly ED counts of: (1) cannabis-induced psychosis [0.34 (95% CI -4.1; 4.8; P = 0.88)]; (2) schizophrenia [24.34 (95% CI -18.3; 67.0; P = 0.26)]; (3) alcohol-induced psychosis [0.61 (95% CI -0.6; 1.8; P = 0.31); or (4) amphetamine-induced psychosis [1.93 (95% CI -2.8; 6.7; P = 0.43)]. CONCLUSION Implementation of Canada's cannabis legalization framework was not associated with evidence of significant changes in cannabis-induced psychosis or schizophrenia ED presentations. Given the potentially idiosyncratic rollout of Canada's cannabis legalization, further research will be required to establish whether study results generalize to other settings.

Participation in Canadian Managed Alcohol Programs and Associated Probabilities of Emergency Room Presentation, Hospitalization and Death: A Retrospective Cohort Study. Alcohol Alcohol 2022; 57:246-260.

Abstract
INTRODUCTION Managed Alcohol Programs (MAPs) are designed to improve health and housing outcomes for unstably housed people with an alcohol use disorder (AUD). The present study assesses the association of MAP participation with healthcare and mortality outcomes. METHODS A retrospective cohort study assessed health outcomes for 205 MAP participants and 128 controls recruited from five Canadian cities in 2006-2017. Survival and negative binomial regression models were used to calculate hazard ratios (HR) of death and emergency room (ER) visits and hospital bed days (HBDs). Covariates included age, sex, AUD severity and housing stability score. RESULTS In fully adjusted models, compared with times outside MAPs, participants had significantly reduced risk of mortality (HR = 0.37, P = 0.0001) and ER attendance (HR = 0.74, P = 0.0002), and fewer HBDs yearly (10.40 vs 20.08, P = 0.0184). Over the 12 years, people enrolled in a MAP at some point had significantly fewer HBDs per year than controls after MAP enrolment (12.78 vs 20.08, P = 0.0001) but not significantly different rates of death or ER presentation. MAP participants had significantly more alcohol-related but significantly fewer nonalcohol-related ER presentations than controls. CONCLUSION Attendance at a MAP was associated with reduced risk of mortality or morbidity and less hospital utilization for individuals with unstable housing and severe AUDs. MAPs are a promising approach to reduce mortality risk and time spent in hospital for people with an AUD and experiencing homelessness.

Abstract
BACKGROUND Harm reduction programs often lack community-based support and can be controversial, despite data demonstrating effectiveness. This article describes one small Alaskan community's development of a harm reduction managed alcohol program (MAP) in the context of a city-run quarantine site for individuals experiencing homelessness. The MAP was developed to support quarantining by COVID-19-exposed or COVID-positive individuals who also experienced chronic homelessness, a severe alcohol use disorder, and heightened health risks related to potentially unsupported alcohol withdrawal. METHOD Five interviews with key informants involved in planning or implementation of the MAP were conducted using rapid qualitative analysis and narrative analysis techniques. OUTCOME This study documents the planning and implementation of an innovative application of a managed alcohol harm reduction intervention in the context of the COVID-19 pandemic. In this instance, a MAP was used specifically to limit hospital admissions for alcohol withdrawal during a surge of cases in the community, as well as to mitigate spread of the virus. Key informants report no residents enrolled in the MAP program as a part of quarantine required hospitalization for withdrawal or for COVID symptoms, and no shelter resident left the quarantine site while still contagious with COVID-19. Additionally, the level of community support for the program was much higher than originally expected by organizers. CONCLUSIONS This program highlighted an example of how a community recognized the complexity and potential risk to individuals experiencing structural vulnerability related to homelessness and a severe AUD, and the community at large, and was able to create an alternative path to minimize those risks using a harm reduction strategy.
