From Reuters Health yesterday:
Heart attack rates dropped among older adults in Scotland in the decade after a nationwide indoor smoking ban took effect, a new study suggests. Scotland banned smoking in all enclosed public spaces and workplaces in 2006. There was a 17% reduction in heart attacks in the first year after the ban took effect, compared to just a 4% decline over the same period in England, where public smoking rules didn’t change, the study team notes. In Scotland between 2000 and 2016, there were [sic] a total of 117,161 heart attacks.
