This is a study that was published in the New England Journal of Medicine done on the safety of e-cigs or better known as vaping. The article states, "They found that vaping 3 milligrams of e-cigarette liquid at a high voltage can generate 14 milligrams of loosely affiliated or "hidden" formaldehyde." How does 3 milligrams of matter, or mass, turn into 14 milligrams of mass? If I understand Conservation of Mass correctly mass can neither be created or destroyed, it just changes forms. Is what I'm suggesting completely off-base, or is the above citation entirely impossible, physically?
