should police departments bust mushroom stores?

Sunday, July 20, 2025 | | 0 comments

Should police departments bust mushroom stores?  This paper reviews 104 peer-reviewed studies to assess the public health impact of recreational psychedelic use.  This is helpful for city councillors and police departments as NOT BUSTING mushroom / psychedelic stores can offer benefit to the community as violence and addictions are reduced and mental health is improved.

Title: Beyond Prohibition: A Public Health Analysis of Naturalistic Psychedelic Use
Authors: Mark Haden, Sarah A. Paschall, Birgitta Woods
Published in: Journal of Psychedelic Studies (2025)


Key Findings

Mental Health Benefits

  • Associated with significant reductions in depression, anxiety, PTSD, substance use disorders, interpersonal violence, and suicidality.
  • Enhances emotional well-being, psychological flexibility, empathy, and social connectedness.
  • May outperform traditional protective factors (e.g., family stability) in reducing criminal recidivism.

Well-Being and Personal Growth

  • Users report greater mindfulness, reduced neuroticism, and enhanced emotional regulation, especially in ADHD, OCD, and trauma-affected populations.
  • Strong association with spiritual experiences, personal insight, and nature connectedness, which may lead to pro-environmental behaviors.
  • Linked to positive personality shifts (e.g., increased openness, decreased neuroticism).

Addiction and Violence Reduction

  • Use is associated with lower rates of substance dependence, including alcohol, tobacco, opioids, and stimulants.
  • Reductions in intimate partner violence and interpersonal aggression reported.
  • Microdosing linked to improved mental health, creativity, and pain tolerance.

Physical Health and Functioning

  • Psychedelic users report better overall health, including lower rates of obesity, hypertension, heart disease, and diabetes.
  • Reduced sick leave and improved outcomes in marginalized populations, older adults, and those with eating disorders or chronic pain.

Adverse Effects

  • Minority of users report negative outcomes such as anxiety, confusion, or lingering psychological effects.
  • Risk factors include: youth, high doses, poor set and setting, pre-existing mental health issues (especially bipolar or psychosis risk), and lack of experience.
  • Despite challenges, most users still perceive benefits, even from difficult experiences.

Cultural Models & Harm Reduction

  • Indigenous traditions emphasize set, setting, and dose—core pillars for safe use.
  • Western policies lack these safeguards, relying instead on prohibition, which the authors argue causes more harm than the substances themselves.
  • A public health approach—including education, safe access, and evidence-based regulation—is recommended.

Conclusions

  • The benefits of naturalistic psychedelic use consistently outweigh the harms.
  • Prohibitionist policies are outdated and unsupported by evidence.
  • The paper calls for decriminalization, regulated access, and public education, drawing from both scientific findings and Indigenous harm-reduction models.

Beyond prohibition: A public health analysis of naturalistic psychedelic use

 

MARK HADEN, SARAH A. PASCHALL and BIRGITTA WOODS

Published July 2025

 

ABSTRACT

Psychedelic drug use is experiencing a global resurgence, both in clinical research and community

settings. This paper presents a comprehensive public health analysis of the naturalistic use of

psychedelics—defined as use outside clinical or research environments. Drawing on a review of 104

peer-reviewed articles, this analysis evaluates the mental, physical, and social outcomes associated with

substances such as psilocybin, LSD, MDMA, mescaline, and 5-MeO-DMT. Findings indicate that

naturalistic psychedelic use is associated with reductions in depression, anxiety, PTSD, substance use

disorders, interpersonal violence, and suicidality, while enhancing emotional well-being, social

connectedness, spirituality, nature relatedness, psychological flexibility and physical health. These

benefits are observed across diverse populations in many countries, including individuals with trauma,

addictions, and chronic pain, as well as in older adults and marginalized groups. Importantly, while

adverse effects can occur, they are typically short-lived and often associated with identifiable risk factors

such as youth, high doses, psychological vulnerability, and poor set and setting. Drawing on harm

reduction principles and Indigenous cultural models, the paper outlines how public education and safe

use guidelines—emphasizing mindset, environment, and dosage—can mitigate risks. The data suggest

that current prohibitionist drug policies are both outdated and harmful and that a shift toward legalization,

regulated access, and evidence-informed education is not only justified but urgently needed.

A public health approach to psychedelics, one grounded in safety, inclusion, and scientific evidence,

offers the most rational path forward.

 

Sincerely,

Mark Haden

 

Free public dialogue on drug policy.

Free public dialogue on drug policy.

 

The evening of May 15th at 7pm (SFU Woodwards).

 

The event will be a public forum/dialogue featuring a panel of international experts on drug policy looking at a future beyond prohibition where we examine various models of legal regulation of substances—what that would look like, how these models would work, and the impact they would have on society more generally. We’re hoping to answer the quesion: In a post-prohibition system, what needs to be done to remedy the harms to victims of the war on drugs and how do we create a just, healthy, and safe system moving forward.

Hello all,

 

I am writing to inform you that as of today, Health Canada has launched a public consultation on potential next steps in the Canadian Drugs and Substances Strategy (CDSS). We would like to invite valued stakeholders, including you or your organization, to provide feedback on this consultation.

 

The purpose of this consultation is to engage Canadians on new and innovative ideas on how to further strengthen the federal government’s approach to substance use issues through the CDSS. The consultation will last for 90 days, closing on December 4, 2018, and we encourage you to participate. We would also appreciate you sharing this email amongst your networks so that we may reach as many interested Canadians as possible.

 

Below you will find a link to the consultation website, where you will be able to undertake a survey to provide your feedback on the CDSS.  This survey is based on key themes, including:

·         Taking action on the root causes and risk factors of problematic substance use

·         Reducing stigma towards people who use drugs

·         Improving access to comprehensive, evidence-based treatment services

·         Applying a public health lens to regulation and enforcement activities

 

Here is the link: Canada.ca/substance-use-consultation

 

We are also attaching electronic copies of postcards and posters to this email announcing the CDSS consultation to the public. We would greatly appreciate if you would post and share these materials in your workspace to help Health Canada gather as many ideas as possible through the CDSS consultation process. Should you wish to receive hard copies to distribute amongst your networks, please feel free to reply to this email.  

 

Thank you in advance for your participation in this consultation. Your unique perspective will be vital to the further development of the CDSS as a health-focussed approach to problematic substance use in Canada.

 

Sincerely,

Bonjour,

 

Je vous écris pour vous informer que Santé Canada a lancé aujourd’hui une consultation publique sur les prochaines étapes possibles de la Stratégie canadienne sur les drogues et autres substances (SCDAS). Nous aimerions inviter les intervenants importants, y compris vous ou votre organisation, à nous faire part de leurs commentaires sur cette consultation.

 

Cette consultation vise à consulter les Canadiens au sujet des idées nouvelles et novatrices sur la façon de renforcer davantage l’approche du gouvernement fédéral à l’égard des problèmes de la consommation problématique de substances par l’entremise de la SCDAS. La consultation durera 90 jours et se terminera le 4 décembre 2018, et nous vous encourageons à y participer. Nous vous saurions également gré de partager ce courriel auprès de vos réseaux afin que nous puissions rejoindre le plus grand nombre possible de Canadiens intéressés.

 

Vous trouverez ci-dessous un lien vers le site Web de la consultation, où vous pourrez répondre à un sondage sur la SCDAS.  Ce sondage est fondé sur les thèmes clés suivants :

  • Prendre des mesures pour s’attaquer aux causes fondamentales de la consommation problématique de substances et aux facteurs de risque qui y sont associés
  • Réduire la stigmatisation des personnes qui consomment des drogues
  • Améliorer l’accès à des services de traitement complets et fondés sur des données probantes
  • Considérer les activités de réglementation et d’application de la loi dans une optique de santé publique

 

Voici le lien: Canada.ca/consultation-consommation-substances

 

J’ajoute également à ce courriel des copies électroniques des cartes postales et des affiches annonçant au public la consultation au sujet de la SCDAS. Je vous serais reconnaissante de bien vouloir publier et partager ces documents dans vos locaux afin de nous aider à recueillir le plus d’idées possible par l’entremise de cette consultation.  Si vous désirez obtenir les cartes postales et les affiches en copies papier, veuillez me le laisser savoir en répondant à ce courriel.

 

Je vous remercie d’avance de votre participation à cette consultation. Votre point de vue sera déterminant pour la poursuite de l’élaboration de la SCDAS comme approche prospective de la consommation problématique de substances au Canada.

 

Cordialement,

Good Morning!

If you were not able to make it to Dr. Susan Boyd's book launch in January, or perhaps you loved it so much you want all your friends to know about it - here is your chance! CDPC's Steering Committee member Dr. Susan Boyd is offering a free talk tomorrow night at the Vancouver Public Library on Canada's History of Drug Prohibition. 

Tuesday, March 6, 2018
7:00 PM PM
Vancouver Public Library: Central Library
350 W. Georgia St.
Alice MacKay Room, Lower Level

Free, everyone welcome!

Human and social development professor Susan Boyd shares from her latest book – an illustrated history of drug prohibition in Canada from the 1800s to present day. Boyd discusses the 'reefer madness' of the 1920s, the psychedelic movement of the 1960s, the harm reduction movement of the 1990s, the legalization of medical cannabis, and how drug laws influence the overdose crisis.

Susan_Boyd-VPL_Event_Poster

Susan Boyd shows how Canada's drug prohibition policies evolved and were shaped by race, class and gender discrimination.

In order to chart the future, it is worthwhile for us as Canadians to know our history of prohibition. You can find the book here. 

Have a wonderful week,

Your small but mighty CDPC team
