Does Vaping Increase Blood Pressure?

What nicotine does to blood pressure and how vaping compares to smoking.

Quick answer: Yes: vaping with nicotine temporarily raises blood pressure, primarily through nicotine's stimulant effect on the sympathetic nervous system. The increase is short-term and returns to baseline once nicotine clears. Long-term effects on blood pressure from vaping appear lower than from smoking, which also raises blood pressure through carbon monoxide and other combustion products.

Blood pressure is a key cardiovascular health marker, and anyone with hypertension or cardiovascular concerns is right to ask this question. The answer requires separating the acute (immediate) effects from any chronic (long-term) impact.

How Nicotine Affects Blood Pressure

Nicotine is a stimulant that activates the sympathetic nervous system: the body's "fight or flight" mechanism. When nicotine reaches the brain and bloodstream, it triggers the release of adrenaline, which causes the heart to beat faster and blood vessels to constrict. Both of these actions raise blood pressure.

This effect is temporary. Blood pressure rises within minutes of vaping and typically returns to normal within 20 to 30 minutes as nicotine levels fall. For most healthy adults, this transient rise is not clinically significant. For people with pre-existing hypertension or cardiovascular disease, it is a more important consideration.

Vaping vs Smoking: Blood Pressure Impact

Factor	Cigarette smoking	Vaping with nicotine
Nicotine: acute BP rise	Yes	Yes: comparable acute effect
Carbon monoxide	Yes: reduces oxygen capacity, increases cardiovascular load	No: no combustion
Endothelial damage (vessel walls)	Significant: contributes to long-term hypertension	Less: reduced without combustion compounds
Oxidative stress	High: many reactive oxygen species in smoke	Lower: present but substantially reduced
Long-term BP impact	Associated with chronic hypertension	Less data: likely lower than smoking

How Large Is the Blood Pressure Rise from Vaping?

Studies measuring acute blood pressure response to vaping typically show a rise of around 5 to 10 mmHg systolic immediately after vaping with nicotine. For context, normal blood pressure is around 120/80 mmHg. A temporary rise to 128/85 mmHg for 20 minutes is not the same as having chronically elevated blood pressure, which is what causes long-term cardiovascular damage.

If you have hypertension or cardiovascular disease: Speak with your GP or cardiologist about vaping specifically. Even temporary blood pressure rises from nicotine are more clinically relevant if your baseline BP is already elevated. Your healthcare team can advise on the most appropriate approach for managing nicotine alongside your cardiovascular health.

What Happens to Blood Pressure When You Switch from Smoking to Vaping?

Switching from smoking to vaping removes carbon monoxide from the equation. CO is particularly harmful cardiovascularly because it binds to haemoglobin 200 times more strongly than oxygen, reducing the blood's oxygen-carrying capacity and forcing the heart to work harder. CO levels in the blood normalise within 24 hours of stopping smoking. Many people who switch report improved cardiovascular readings within weeks to months.

Frequently Asked Questions

This is a question for your GP or cardiologist. Nicotine temporarily raises blood pressure with each vaping session. If your BP is already elevated and poorly controlled, these transient spikes add cardiovascular risk. If you smoke and have hypertension, switching to vaping is still likely to be better than continuing to smoke but the ideal is to reduce nicotine intake over time with medical support.

Yes. Nicotine raises both blood pressure and heart rate acutely. Heart rate typically rises by 10 to 20 beats per minute after vaping with nicotine and returns to normal within 20 to 30 minutes. As with blood pressure, this is a transient effect in healthy adults. In people with arrhythmias or other cardiac conditions, the significance is greater.

Without nicotine, the primary mechanism for blood pressure elevation is absent. Nicotine-free vaping does not cause the adrenaline-driven vasoconstriction that raises BP. Some very small effects from the inhalation act itself may exist in theory, but they are clinically negligible for most people.

Yes, it is advisable. If you have a BP measurement scheduled, avoid vaping (and caffeine) for at least 30 minutes beforehand. Nicotine temporarily elevates BP and could result in a reading that does not accurately reflect your true resting blood pressure. Most clinical guidelines for accurate BP measurement recommend avoiding nicotine and stimulants for 30 minutes prior to testing.
