On June 29, 2010, the Prevent All Cigarette Trafficking Act (PACT Act) went into effect. This federal law amends the Jenkins Act, 15 U.S.C. Chapter 10A, which governs the collection of taxes on, and trafficking in, cigarettes and smokeless tobacco. The PACT Act revised definitions in the Jenkins Act, provided new requirements for registration reporting, record keeping, and increased penalties for criminal violations. The PACT Act also generally prohibits mailing cigarettes and smokeless tobacco through the U.S. Postal Service. On December 27, 2020, the PACT Act was amended to include Electronic Nicotine Delivery Systems or “ENDS”. This change is effective March 27, 2021.
