Reversibility post-cessation : Evidence suggests partial restoration of oral and gut microbiota after smoking cessation (e.g., Neisseria recovery in saliva, Lactobacillaceae increase with modified-risk products), but long-term ecological resilience and its health implications require longitudinal human cohort studies
