About PPX
The question for this industry is no longer how to make it legal. It is how to compete and grow in newly legal markets. PPX was built for that second question.
PPX is a strategic pillar within Prohibition Partners — the organisation that has tracked, analysed and shaped the global cannabis industry for a decade.
Our clients don't just get campaigns. They get proprietary market intelligence, direct introductions to investors and operators, visibility through the world's largest B2B cannabis media network, and strategic guidance informed by regulatory insight across every major market.
We turn that platform into commercial outcomes: faster launches, smarter positioning, stronger networks, measurable growth.
