The policy implementation playbook: a cross-policy taxonomy of post-adoption tobacco industry tactics.

BACKGROUND: Tobacco industry interference during policy development is well documented, yet evidence on how the industry responds after policies are adopted and enter into force remains fragmented across policy domains and jurisdictions. This study systematically examines post-adoption tobacco industry conduct across key tobacco control measures and develops a cross-policy taxonomy of post-adoption tactics. We conducted as scoping review and qualitative evidence synthesis of peer-reviewed and grey literature, searching six data bases and Tobacco Control's News Analysis archive. Using inductive coding, we identified recurring forms of post-adoption industry activity and synthesised these into a conceptual taxonomy - the Policy Implementation Playbook (PIP).

RESULTS: We included 308 sources (210 peer-reviewed articles and 98 News Analysis items) spanning approximately 50 countries across all WHO regions, although documentation was concentrated in a limited number of settings. The PIP identifies five recurrent tactics. One - pre-emptive adaptation - occurs before a policy enters into force and includes stockpiling, transitional packaging, and early product or marketing adjustments. After a policy enters into force, the industry may disregard requirements, adopt token implementation that signals formal compliance while reducing practical impact, circumvent regulation through product-, design-, or channel-based tactics, or seek to influence implementation indirectly through retailers, hospitality actors, public authorities, and enforcers. Circumvention was the most frequently documented response across most policies, though its specific form varied across regulatory domains. Disregard and pre-emptive adaptation were also common, while token implementation was largely confined to health warning requirements. Smoke-free regulations more often elicited intermediary-focused strategies aimed at shaping interpretation, enforcement, and compliance.

CONCLUSIONS: By conceptualising policy implementation as a contested political arena and synthesising recurrent tobacco industry tactics across policies, the PIP extends existing models of corporate political activity. The taxonomy provides a structured basis for anticipating post-adoption corporate conduct and strengthening regulatory design, implementation, and governance in tobacco control and the regulation of other unhealthy commodities.
