Tobacco control law implementation in a middle-income country: Transnational tobacco control network overcoming tobacco industry opposition in Colombia

The objective of this paper is to examine the implementation of Colombia's tobacco control law. Methods involved are triangulated government legislation, news sources, and interviews with policy-makers and health advocates in Colombia. Colombia, a middle-income country, passed a tobacco control law in 2009 that included a prohibition on tobacco advertising, promotion, and sponsorship; and required pictorial health warning labels, ingredients disclosure, and a prohibition on individual cigarette sales. Tobacco companies challenged the implementation through litigation, tested government enforcement of advertising provisions and regulations on ingredients disclosure, and lobbied local governments to deprioritise policy responses to single cigarette sales. A transnational network including international health groups and funders helped strengthen domestic capacity to implement the law by; promoting public awareness of Ley [Law] 1335; training local health department staff on enforcement; facilitating health agencies' sharing of educational strategies; and providing legal defence assistance. This network included vigilant efforts by local health groups, which continuously monitored and alerted the media to noncompliance, engaged government officials and policy-makers on implementation, and raised public awareness. Support from international health NGOs and funders and continuous engagement by local health groups enhanced implementation capacities to counter continued tobacco industry interference and ensure effective tobacco control implementation.
