Passive smoking: Research & Science
Passive smoking is the inhalation by individuals other than the smoker of tobacco smoke, called second-hand smoke, passive smoke (SHS) or environmental tobacco smoke (ETS). It occurs when tobacco smoke diffuses into the surrounding atmosphere as an aerosol pollutant, which leads to its inhalation by nearby bystanders within the same environment. Exposure…

Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 115 structured relationships around Passive smoking. Examples in this analysis include Passive smoking → causes → about 600 and Passive smoking → causes → about 900. The table shows each extracted connection, where it came from and its confidence.
