Strengthening the Evidence: Triangulation, replication, and the role of e-cigarettes in smoking cessation

Replication of studies is important, but triangulating data sources provides stronger evidence. Both replication and triangulation are crucial for building robust evidence on the effectiveness and acceptability of e-cigarettes for smoking cessation. Current research from various study designs shows that nicotine-containing e-cigarettes help adults who smoke to quit successfully and maintain abstinence. Emerging evidence also suggests that e-cigarettes are acceptable among individuals facing social disadvantages. However, there is ongoing debate about their role among young people. Using triangulation models, this talk will evaluate the strength of evidence for e-cigarette use among adults compared with young people.
