  1. NRT: nicotine replacement therapy; SD: standard deviation
  2. *Nine focus groups conducted in London (n = 3), Birmingham (n = 3), and Glasgow (n = 3); four focus groups conducted in Rome and Tokyo; twelve focus groups conducted in Atlanta (n = 4), Los Angeles (n = 4), and Philadelphia (n = 4)
  3. **In-depth interviews conducted in North Carolina, US. The sample was recruited to have equal numbers of people who use a single TNP (e.g., balanced across cigarettes, cigar/cigarillos, e-cigarettes, smokeless tobacco, and other TNPs) and people who were poly-users of TNPs
