🫁 Vaping vs. Smoking Lung Damage (2025 Studies)

COPD Risk	23% lower vs. smokers	80% of COPD cases

Key Findings:

• Vaping avoids combustion toxins (e.g., polycyclic aromatic hydrocarbons) but introduces metal nanoparticles from coil degradation 
• NIH 2025 study: Chronic vapers show impaired endothelial function (similar to smokers)

2. EVALI vs. Smoking-Related Pneumonia

• EVALI: Linked to THC/vitamin E acetate (rare in nicotine-only vapes) 
• Smoking: Causes lipoid pneumonia from tar buildup
