Research: Heavy smokers who switch to vaping risk of heart disease drop

Scientists said their study is the first definitive proof that vaping is better for the cardiovascular system than smoking.

They stressed that non-smokers should steer clear of e-cigarettes, because the devices come with their own harms.

But for ‘chronic’ tobacco smokers – those who have smoked at least 15 cigarettes a day for two years – switching resulted in an almost immediate benefit.
