Report: Global Cannabis Regulatory Summit Synopsis

 

Event Overview

I recently attended and moderated a panel at the inaugural Global Cannabis Regulatory Summit, held in Washington, D.C. on March 26-27, 2025. Hosted by Artemis Growth Partners, Tenacious Labs, and The Liaison Group, the invite-only attendees represented 17 nations, including high-level government officials, UN treaty body members, regulators, investors, legal experts, healthcare professionals, researchers, insurance providers, trade association representatives, and executives from publicly traded cannabis companies.

The Summit was organized around two central pillars: medical vs. adult-use cannabis regulation, and the need for global harmonization and standardization. Sessions balanced education, problem identification, and the proposal of practical solutions.

Below is my summary of the key themes and takeaways from the event. The insights and views expressed are my own and do not necessarily reflect those of any individual speaker, organization, or event organizer.

 

Key Themes & Takeaways


1. The Critical Need for Standardization

A unifying message across nearly every session was the urgent call for harmonization and standardization. Regardless of whether the discussion focused on patient access, healthcare, investment risk, or regulation, stakeholders consistently recognized that global inconsistencies create confusion, risk, and inefficiency.

During a panel moderated by Dave Vaillancourt (S3 Collective), leadership from the U.S. Pharmacopeia (USP), ASTM International, and the International Organization for Standardization (ISO) highlighted how their organizations—collectively responsible for over four centuries of standard-setting across regulated industries—offer practical pathways to overcome these barriers.

Key Insight: Standardization bodies are uniquely positioned between conservative treaty organizations and fast-moving industry actors. They are the ideal neutral force to bridge global gaps.

2. Medical vs. Adult-Use Markets

There was broad agreement on the need to clearly delineate medical from adult-use cannabis, both in policy and practice. Under international treaties, cannabis is permitted for medical and scientific use, with each nation determining its own definitions. However, global models vary widely.

Unique attributes of various medical access models:

United States: Dispensary model for distribution, health care providers (HCPs) ‘recommend’. The latitude in which HCPs are allowed to recommend based on conditions varies greatly between states.

  • Georgia (US): First in the US to institute pharmacy-based access which has been met with federal challenges.

Canada: Medical cannabis is dispensed only by mail, with no advice allowed at adult-use stores. Of note, veterans medical cannabis is reimbursed by the national health care system.

Colombia: Considered a highly restrictive market in terms of patient access with a very limited patient enrollment (approx 1,000 adults), has resulted in an export-dominant market. The top 2 producers export >80% of all medical cannabis.

Brazil: Counter to Colombia, their program emphasized patient access, has lowered barriers to conducting clinical trials, and uses Sanitary Authorizations rather than the traditional approved drug pathway to ensure access to products.

Argentina: Prioritizes smaller operations and permissible social use 

Mexico: Despite legalizing in 2017, no approved legal supply has been established

Saint Vincent and the Grenadines: Is prioritizing the local culture and embracing traditional cultivation and access as they develop their program.

France: A medical cannabis pilot program is now in its 5th year, and the costs of the medicines are reimbursed via their national healthcare system.

Czech Republic:  Rescheduled before the UN, with first license being issued back in 2013

Malta (adult use): Oversight is predominantly through random testing of products at collectives and social clubs

 

Key Challenges

  • Inconsistent definition of “medical.”
  • Lack of standardized dosage forms.
  • Lack of harmonized framework to address the unique nature of a complex herbal material with respect to the level of evidence needed to support medical use (i.e. a real-world evidence approach rather than the gold standard of clinical trials which was designed for single molecule drugs), and a consistent level of standards needed to define the key quality attributes.
  • Absence of healthcare reimbursement in most jurisdictions.\
  • Lack of a process to establish and monitor medical cannabis quotas by the International Narcotics Control Board (INCB) due to the lack of product consistency and dose form standardization.
  •  

3. Industry’s Role and Risks

The cannabis industry must take responsibility for being at the forefront with science and self-regulation to mitigate emerging risks—especially around impact litigation and public health.

  • Learning from the alcohol industry, experts emphasized the risk of impact litigation if cannabis companies fail to lead with science when producing, commercializing, and marketing their products.
  • Experts highlighted the benefits of leading with science, including building and maintaining consumer trust, transparency, and product quality.
  • Engaging with regulators and public health experts through standard-setting and data sharing helps protect commercial interests and ensure long-term market viability.

 

Key Point: Industry-led innovation must be paired with public accountability. Establishing and following recognized standards is a critical step in this process.

 

4. Education as a Foundational Gap

 

The Summit revealed a pervasive gap in education across the cannabis ecosystem:

  • Healthcare Providers lack consistent training and guidelines
  • Patients and Consumers need better information to navigate safe and effective use
  • Regulators and Policymakers require updated, evidence-informed frameworks to guide decisions

     

Proposed Solution: Develop systems where educated healthcare professionals can work with governments to help establish national supply needs, quotas, and best practices—especially critical for maintaining treaty obligations.

 

S3 Collective Perspective & Role

As moderator of the Summit’s panel on standardization, the S3 Collective demonstrated how it operates at the intersection of industry, standards organizations, government, and research. As the leading global think tank, the S3 Collective provides the structure, data, and trusted leadership to accelerate solutions that benefit all stakeholders in the cannabis space.

Next Step for Stakeholders: Engage with standards bodies (USP, ISO, ASTM) and conveners like the S3 Collective to participate in the development of robust, science-driven frameworks that bridge global gaps in cannabis regulation.

 

What to expect next:

A detailed report is being prepared by Prohibition Partners that will be published by the end of Q2 2025. This report will be a compilation of 3-5 page white papers for each panel summarizing the key points of the discussion with a focus on setting out key challenges and action steps to resolve.

 

Key resources that were highlighted and/or discussed:

  • White Paper: M. Woodbridge, “Cannabis Quality – the need for science-based global harmonisation of standards: Findings from the USP-ASTM Global Workshops on Cannabis Quality” (2024)
  • White Paper: ASTM International, White Paper: Adult-Consumer Use vs. Medical Use (2023)
  • Public survey by ASTM International Committee D37 to identify critical gaps in standards for cannabis and hemp for all stakeholders to complete that will guide the development of new standards based on identified market need.
  • Journal article: Mravcik, et. al. “Psychomodulatory substances: New legislative framework for control of psychoactive substances in Czechia” (2024)
  • Government Report: EU Drug Market: Cannabis — In-depth analysis (last updated, November 2023)
  • Trade Organization Report: Transform Drug Policy Foundation “High Returns: The economic benefits of UK cannabis legalisation” (2025)
