Pregnant women are more likely to smoke if they live in areas with lots of shops selling cigarettes, a study has suggested.
Edinburgh University researchers looked at maternity records in tandem with information on all Scottish tobacco outlets.
They said their study is the first to reveal the links between tobacco availability and smoking in pregnancy.
Previous research suggested tobacco was more available in deprived areas.
The research team said "restricting the supply of tobacco could help tackle health inequalities".
