Flat-dwelling children exposed to neighbours' smoke too (BBC)

Children living in flats have 45% more exposure to tobacco smoke than those in detached houses, a US study says.

Researchers from Harvard and Rochester Universities say that is because the smoke seeps through walls and shared ventilation systems.

They tested cotinine levels in blood samples from 5,000 children across the US for the study in Pediatrics.

Action on Smoking and Health (ASH) said there was a "strong case" for making blocks of flats smoke free.

Researchers limited the sample in this study to children who live in a household where nobody smokes.
