The Protocol to Eliminate Illicit Trade in Tobacco Products is an international treaty with the objective of eliminating all forms of illicit trade in tobacco products through a package of measures to be taken by countries acting in cooperation with each other: it is a global solution to a global problem. The Protocol was developed in response to the growing illicit trade in tobacco products, often across borders. Illicit trade poses a serious threat to public health because it increases access to – often cheaper – tobacco products, thus fueling the tobacco epidemic and undermining tobacco control policies. It also causes substantial losses in government revenues, and at the same time contributes to the funding of international criminal activities.
