2026 Cornish home sensors: second‑hand vaping emits fewer microplastic/PM particles than tobacco smoke — what UK vapers and families need to know

While promising for harm‑reduction conversations, methodological limits and the dominance of textile fibres as indoor microplastic sources mean families should still focus on ventilation, cleaning and reducing indoor smoking.
