Asthma UK says: "We are happy to pledge our support for Scotland's Charter for a tobacco-free generation. The health impact of smoking on asthma is enormous. Not only does it trigger life threatening asthma attacks in people with asthma, but it can cause people to develop asthma. It also reduces lung function and can lessen the effectiveness of some asthma medicines.
"Tragically asthma attacks kill a classroom of children every year in the UK. Studies show children with asthma who are exposed to environmental tobacco smoke have more severe asthma symptoms, a higher frequency of asthma attacks, more pronounced airway responsiveness, and a lower level of lung function than children with asthma who are not exposed to second-hand smoke. If you are a smoker you'll find your child's asthma is harder to control - they might have a persistent wheeze or cough, and may not sleep well.
"Scotlands Charter will help take the 1 in 14 people with asthma in Scotland - and particularly more than 72,000 children - a step closer to benefiting from a smoke free future."
