“This explains the decrease in penile girth effect of nicotine, in particular nicotine ingested by smoking or vaping. That's right, smoking and vaping reduces penis size and also will have damaging effects on the blood lining endothelial tissue. So over time it actually is impairing blood's ability to get to the penis chronically as well as to other organs of the body.”
