How trials define abrupt quitting
Participants continue their usual smoking until a specified quit date, then stop. They may still receive counseling or medication depending on the trial.
How trials define reduction-to-quit
Participants progressively reduce cigarettes before a planned stop date. The pace, behavioral support and medication vary, which makes the intervention more than simply ‘smoke less.’
What the review can and cannot decide
Average results do not identify which approach will feel more workable for a particular person. They do show that one method should not be dismissed as universally inferior.
What to keep in mind
Common questions
Is cold turkey the same as no help?
Not necessarily. Abruptly stopping cigarettes can be combined with counseling or approved cessation medication.
Can I reduce without choosing a stop date?
That is different from most reduction-to-quit trials, which use a structured path toward cessation.
