This form of ayahuasca-assisted therapy appears to be associated with statistically significant improvements in several factors related to problematic substance use among a rural aboriginal population. These findings suggest participants may have experienced positive psychological and behavioral changes in response to this therapeutic approach, and that more rigorous research of ayahuasca-assisted therapy for problematic substance use is warranted.

Minimum pricing is a promising strategy for reducing the public health burden associated with hazardous alcohol consumption. Pricing to reflect percentage alcohol content of drinks can shift consumption toward lower alcohol content beverage types.

Introduction and Aims A previous observational study of ayahuasca‐assisted therapy demonstrated statistically significant reductions in self‐reported problematic cocaine use among members of an Indigenous community in Canada. This paper aims to qualitatively explore the impact of ayahuasca‐assisted therapy on addiction and other substance use‐related outcomes and elucidate the lived experiences of participants. Design and Methods Qualitative interviews were conducted with 11 adult Indigenous participants of the ayahuasca‐assisted ‘Working with Addiction and Stress’ ceremonial retreats (June–September 2011). Semi‐structured interviews assessed experiences of participants following the retreats at 6‐month follow up. Thematic analysis of interview transcripts was conducted. Results Narratives revealed that the retreats helped participants identify negative thought patterns and barriers related to their addiction in ways that differed from conventional therapies. All participants reported reductions in substance use and cravings; eight participants reported complete cessation of at least one substance at follow up. Increased connectedness with self, others and nature/spirit was described as a key element associated with reduced substance use and cravings. Discussion and Conclusions This analysis expands upon prior quantitative results highlighting the therapeutic potential of ayahuasca‐assisted therapy and provides important contextual insights into why ayahuasca‐assisted therapy may have been beneficial for members of an Indigenous community seeking to address their problematic use of substances. Given limited efficacy of conventional treatments for resolving addiction issues, further research should investigate the role of ayahuasca and other psychedelic‐assisted therapies in enhancing connectedness and other key factors that may improve well‐being and reduce harmful substance use.

Aims: To compare Canadian provinces across 10 research-based alcohol policy and program dimensions. Design and Measures:The 10 Canadian provinces were assessed on the following 10 policy dimensions: alcohol pricing; alcohol control system; physical availability; drinking and driving; marketing and advertising; legal drinking age; screening, brief intervention, and referrals; server training, challenge, and refusal programs; provincial alcohol strategy; warning labels and signs. Data were collected from official documents, including provincial legislation, regulations, and policy, and strategy documents. Three international experts on alcohol policy contributed to refining the protocol. Provincial scores were independently determined by two team members along a 10-point scale for each dimension, and the scores were expressed as a percentage of the ideal. Weighting of dimensions according to scope of impact and effectiveness was applied to obtain the final scores. National and provincial scores were calculated for each dimension and consolidated into overall averages.Findings: Overall, the consolidated national mean is 47.2% of the ideal, with Ontario scoring highest at 55.9%, and Québec lowest at 36.2%. Across dimensions, Legal Drinking Age and Challenge and Refusal Programs scored highest at 75% and 61%, respectively, while Warning Labels and Signs scored lowest at 18% of the ideal. Pricing, rated third highest among dimensions at 57%, should nevertheless remain a priority for improvement, given it is weighted highest in terms of effectiveness and scope. Conclusions and Implications:Policy dimension scores vary among the provinces, with substantial room for improvement in all. Since spring 2013, several provinces have taken steps to implement specific alcohol policies. Concerted action involving multiple stakeholders and alcohol policies is required to reduce the burden of alcohol problems across Canada.

Issues Canada recently introduced a public health‐based regulatory framework for non‐medical cannabis. This review sought to identify a comprehensive set of indicators to evaluate the public health and safety impact of cannabis regulation in Canada, and to explore the ways in which these indicators may be expected to change in the era of legal non‐medical cannabis. Approach Five scientific databases were searched to compile a list of cannabis‐related issues of interest to public health and safety. A set of indicators was developed based on topics and themes that emerged. Preliminary evidence from other jurisdictions in the USA and Canada that have legalised medical and/or non‐medical cannabis (e.g. Colorado, Washington) was summarised for each indicator, wherever possible. Key Findings In total, 28 indicators were identified under five broad themes: public safety; cannabis use trends; other substance use trends; cardiovascular and respiratory health; and mental health and cognition. Preliminary trends from other legalised jurisdictions reveal little consensus regarding the effect of cannabis legalisation on public health and safety harms and an emerging body of evidence to support potential benefits (e.g. reductions in opioid use and overdose). Implications In addition to indicators of commonly discussed challenges (e.g. cannabis‐related hospitalisations, cannabis‐impaired driving), this review led to the recommendation of several indicators to monitor for possible public health and safety improvements. Conclusion In preparing a comprehensive public health and safety monitoring and evaluation system for cannabis regulation, this review underscores the importance of not only measuring the possible risks but also the potential benefits.
