Kay Boycott, Chief Executive of Asthma UK, says: "We welcome the new law which prohibits smoking in cars when children are present, which we have long supported. The impact of smoking on the health of people with asthma is enormous; it reduces lung function, increases the risk of asthma attacks and can cut down the effectiveness of some asthma medicines. Tragically asthma attacks kill a classroom of children every year in the UK so this law is especially important; 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 c children with asthma who are not exposed to second-hand smoke. Parliament has made great progress today but more must be done. We now need to see standardised packaging on all tobacco products become law before the end of this parliament."
