aping can irritate the lungs and airways, leading to respiratory symptoms such as coughing, wheezing, and shortness of breath. Inhalation of e-cigarette aerosol can also expose the lungs to harmful chemicals, including fine particles, volatile organic compounds, and heavy metals, which may contribute to lung damage and respiratory problems.

Vaping can affect the cardiovascular system, increasing heart rate and blood pressure, constricting blood vessels, and promoting the release of adrenaline. While the cardiovascular effects of vaping may be less severe than smoking traditional cigarettes, long-term use of e-cigarettes may still increase the risk of heart disease, stroke, and other cardiovascular problems.

Many e-cigarettes contain nicotine, which is highly addictive. Nicotine exposure through vaping can lead to dependence, cravings, and withdrawal symptoms when attempting to quit. Nicotine addiction is a significant concern, particularly among young people who may be more susceptible to the addictive effects of nicotine.

Nicotine exposure during adolescence, a period of critical brain development, can have long-lasting effects on brain structure and function. Vaping among teens has been associated with changes in brain circuits involved in reward, learning, and impulse control, increasing the risk of addiction and potentially impairing cognitive performance.

E-cigarette aerosol often contains flavorings, solvents, and other chemicals that may pose health risks when inhaled. While some flavorings are generally recognized as safe for ingestion, their safety when inhaled is less well understood. Additionally, certain chemicals found in e-cigarette aerosol, such as diacetyl, have been linked to lung disease when inhaled.

Vaping has been associated with an increased risk of lung injuries and respiratory symptoms, particularly among individuals who use vaping products containing THC or vitamin E acetate. Cases of e-cigarette, or vaping, product use-associated lung injury (EVALI) have been reported, with symptoms ranging from coughing and chest pain to more severe respiratory distress and lung damage.

Vaping can have negative effects on dental and oral health, including dry mouth, gum irritation, tooth decay, and gum disease. E-cigarette aerosol may contain chemicals that can damage oral tissues and promote bacterial growth, increasing the risk of oral health problems.
