What happens when you quit smoking and start vaping?

The NHS says that ‘stopping smoking is one of the best things you will ever do for your health’ with almost immediate health improvements upon quitting for good.

It says all carbon monoxide is removed from your body after 48 hours; breathing becomes easier after 72 hours; blood circulation improves over two to 12 weeks and your risk of a heart attack (compared to that of a smoker) will have halved after a year.

The Office of Health Improvement & Disparities (OHID) says there are lower health risks for a number of potentially serious health conditions from vaping than smoking.

It says: “Evidence suggests significantly lower relative exposure from vaping compared to smoking in biomarkers that are associated with the risk of:

  • cancer
  • respiratory conditions
  • cardiovascular conditions and
  • other health conditions
