London – – October 06, 2026 -- Prohibition Partners has appointed Heidi Whitman as Managing Director of PPX, a new advisory and media pillar combining the firm's decade-old cannabis market infrastructure with her independent network of regulators, financiers and formulators across the UK, EU and Latin America.
Prohibition Partners merges a decade of client relationships with Whitman's independent advisory book
Prohibition Partners has worked with some clients since 2017, building intelligence, media and events infrastructure including Cannabis Europa, Cannabis Health, Mind Forward and Business of Cannabis. Whitman's own clientele, built across three independent ventures, a company exit and years of advisory work, now gains access to that full network under the PPX structure.
Cannavigia, a compliance software provider, is named as an existing PPX client
Whitman cited Cannavigia, a cannabis traceability and compliance software company, as one of the clients moving into PPX, framing compliance and ethics as central to the pillar's service model. PPX will offer proprietary market intelligence, direct introductions to investors and operators, media visibility and regulatory-informed strategic guidance across major markets.
Stephen Murphy says the appointment turns existing infrastructure into client outcomes
