A government health tour visited Asda in Peterhead to explain the dangers of second-hand smoke.
As 85 per cent of second-hand smoke is invisible and has no smell, it creates a hidden danger most people don’t even consider.
The second-hand smoke can linger for five hours after the visible smoke has disappeared.
The tour will vist six locations in Grampian including Aberdeen’s Union Square.
Scotland recently became the first country in the world to set a target of reducing the proportion of children in Scotland exposed to second-hand smoke in the home from 12 per cent to six per cent by 2020.
