ITC Project

United States of America

In 2002, ITC launched surveys in Australia, Canada, the United Kingdom, and the United States, referred to as the Four Country (4C) Wave 1 Survey.The United States of America is one of the four original countries of the ITC project. It was chosen due to its economic leadership on the world-stage, and also due to the fact that it has not yet ratified the Framework Convention on Tobacco Control (FCTC), which allows for the comparative evaluation of policies at sub-national level. The USA signed the FCTC on May 10, 2003.

In 2016, the ITC Project received funding to evaluate policies that regulate vaporized nicotine products (VNPs), including electronic cigarettes (e-cigarettes), at the population level by examining use and the evolution of the VNP marketplace in Australia, Canada, the United States, and England, referred to as The Four Country Smoking and Vaping Survey (4CV). More information about the tobacco and e-cigarette study is available at:
