How Vaping THC Affects Your Lungs: Health Risks Explained

Vaping THC can cause a range of lung health effects, from short-term irritation to severe, life-threatening conditions. The most serious is EVALI (e-cigarette or vaping product use-associated lung injury), which the CDC linked primarily to vitamin E acetate—an additive found in some illicit THC vape cartridges. Symptoms include cough, chest pain, shortness of breath, nausea, and fever. Even without EVALI, regular vaping can lead to lung inflammation, airway damage, and chronic bronchitis-like symptoms. A 2020 study from the University of California, Davis - Cannabis Research Center found that frequent cannabis vaping was associated with higher rates of respiratory symptoms compared to non-users. The long-term effects are still being studied, but early evidence suggests potential for lung tissue scarring and reduced lung function over years of use. For residents of Tracy, Mountain House, Lathrop, Manteca, and other nearby communities, the safest choice is to buy only from licensed dispensaries like Garden of Eden Tracy, where all THC vapes are lab-tested for contaminants like heavy metals, pesticides, and vitamin E acetate. If you experience any respiratory symptoms after vaping, stop use and consult a healthcare provider.
