Passive smoking isn’t just about the smoker — it’s the invisible cloud around them, like 💨👃🚬 signaling unwanted secondhand smoke. Use 🚭💨 to highlight no-smoking zones or health warnings, and 🏢🚬👶 when discussing indoor smoking near children. For environmental concerns, 🚭🌳 contrasts clean air with smoke. These combos fit well in awareness posts, workplace policies, and family health chats.
