This is just entirely untrue. People generally consume more nicotine when vaping. That much is true. Vaping has significantly less toxins and dangerous chemicals than smoking cigarettes, as well as circumvent the whole tar in the lungs thing. There are no long term studies on vaping, so doctors will always say “we aren’t sure which is worse” but advise that smoking is likely to be far worse for the body than vaping. There is not a single study on earth, nor any doctors I’ve heard, that supports your claim.
