Illicit tobacco trade is a prevailing barrier in the implementation and success of tobacco control policies, particularly the introduction or increase of tobacco tax. It is used as an unfounded argument against the introduction of tobacco tax and as a tool to maintain access to cheap cigarettes when their price increases. This keeps smokers addicted to tobacco and at risk of cancer and other non-communicable disease, as well as making cigarettes more accessible to young people. Hear from research partners on how illicit cigarette trade operates in their countries, the impact it has on communities, and the strategies adopted to limit the impact of illicit trade on the implementation of tobacco control policies.
