Risks to heart health

Recent research has shown that people who use vaping products may be at a higher risk of heart disease. 


Using a vaping product just once was shown to increase people's heart rates and cause their arteries to stiffen, and may cause damage to the lining of the arteries responsible for regulating inflammation and blood clotting.  It can also damage blood vessels, affecting blood flow through the body over time. These conditions can contribute to heart disease or increase risk of heart attacks.
