More information is coming out daily about the hazards of e cigarettes as the FDA decides if and how to regulate the industry. The newest releases explain how ultra fine particles of tin, copper, nickel, and silicates (a form of glass) are inhaled directly into the lungs not only by the person vaping but the bystander as well.
Silicosis is a disease leading to COPD that has a history with construction workers (from insulation) and manucurists (from fake finger nail coatings.) The microscopically small pieces of glass are inhaled into the lungs and make tiny tears in the alveoli of the lung tissue. Air leaks out of the lungs and symptoms include severe disabling shortness of breath, cough, weakness, and weight loss, often leading to death.
Inhaled metals can not just tear holes in your lungs, (as if that weren't enough!) they also travel through the blood stream to vital organs and damage everything in their wake! Check out Metal fume fever, for example.
E cigarettes may actually turn out to be even more risky than Sickerettes!
