Vaping can affect vascular health and oxygen levels in the body, although the extent depends on the specific substances inhaled and individual factors like preexisting health conditions.

Recent research on vaping shows that vaping can have an immediate negative effect on blood vessels. Whether nicotine is present or not, vaping has significant impact on health, and it is not good. If you are thinking it is okay to use non-nicotine vaping, then you are wrong. Studies showed that non-nicotine vaping can also negatively affect cardiovascular health and oxygen levels. While nicotine is a significant contributor to the harmful effects of vaping, other components in e-cigarette aerosols can also pose risks.

How does vaping impact vascular and oxygen levels?

Vascular health

1. Endothelial dysfunction: Vaping can harm the endothelium, the inner lining of blood vessels, leading to reduced nitric oxide availability. Nitric oxide is critical for vasodilation and maintaining blood vessel flexibility. Flavored e-liquids and additives can cause damage to the endothelium, even without nicotine. Studies have shown that flavoring chemicals, such as cinnamon or menthol, can impair blood vessel function.
2. Inflammation: Chemicals in e-cigarette aerosols, including nicotine and flavoring agents, can trigger inflammation, contributing to vascular damage and increasing the risk of atherosclerosis (plaque buildup in arteries). Ingredients like propylene glycol and vegetable glycerin, used as carriers in e-liquids, can cause systemic inflammation when inhaled regularly.
3. Oxidative stress: Vaping can generate free radicals, which promote oxidative stress, which damages blood vessels and contributes to inflammation and plaque formation.

Oxygen levels

1. Carboxyhemoglobin formation: Vaping products produce carbon monoxide as a byproduct, which can bind to hemoglobin and reduce oxygen delivery to tissues.
2. Impaired lung function: Chemicals in vaping aerosols, such as propylene glycol, glycerin, and flavorings, can irritate the lungs, reducing their efficiency in oxygen exchange.
3. Decreased oxygen transport: Nicotine causes vasoconstriction (narrowing of blood vessels), which may reduce blood flow and oxygen supply to tissues.
4. Carcinogens and Byproducts: Heating of e-liquids produces aldehydes (like formaldehyde) and other harmful chemicals, which can irritate the respiratory tract and impair oxygen intake.
5. Carbon Monoxide (CO) Production: While less common in non-nicotine vapes, certain devices and e-liquids may still produce CO, which competes with oxygen for hemoglobin binding.

Key risks and implications

• Heart and blood vessel strain: Regular exposure to vaping aerosols (even without nicotine) can promote inflammation and oxidative damage, increasing the risk of cardiovascular diseases.
• Respiratory complications: Chronic use may lead to reduced lung function, which indirectly affects oxygen delivery to the body.

For cardiovascular and respiratory health, avoiding vaping altogether is advisable, regardless of whether nicotine is present.
