A major new study published in JACC: Advances found that long-term vaping raises blood pressure in young adults. Vapers who never smoked had systolic blood pressure 4.79 mmHg higher than non-vapers. The more puffs per day, the higher the blood pressure. Vaping provided no cardiovascular risk reduction compared to not vaping or smoking. If you vape, these findings are relevant to your heart health — especially if you started vaping without ever smoking.
