OSA is a specific breathing disorder
NHLBI states that smoking can increase sleep-apnea risk; this is risk-factor language, not a claim that smoking causes every case.
Obstructive sleep apnea, central sleep apnea, insomnia, snoring and daytime sleepiness are different endpoints.
Inflammation is a possible pathway
Upper-airway inflammation is a plausible link, but a mechanism cannot identify whether a recorded pause is obstructive apnea.
Airway anatomy, age, body composition and alcohol also matter. How a study selects participants can influence the risk it observes.
A smoking comparison must not become a snoring test
A study recruiting from a sleep clinic does not represent all adults who smoke: its participants may already have symptoms or other risks. Another study may record diagnosed OSA, while a questionnaire counts reported snoring. Those outcomes cannot be combined casually. Smoking may contribute to upper-airway inflammation, but anatomy, age and body composition also matter. Removing one risk factor is not proof that an established obstruction disappears or that treatment can be stopped.
Discuss breathing concerns with local care
A primary-care or sleep-care service can determine what a personal concern requires. This page does not score questionnaires, interpret recordings or select a test or device setting. Public tobacco resources help with smoking questions; they do not replace an OSA care plan.
