Fact: Vaping is less dangerous than smoking. This is one of those facts that doesn’t really need research attached to it. Cigarette smoke contains “carbon monoxide, ammonia, dimethylnitrosamine, formaldehyde, hydrogen cyanide and acrolein,” a British anti-smoking charity explains. Vapour from an e-cigarette contains water and either glycerin or propylene glycol. While it’s true the long-term effects of consuming the latter two in e-cig form have not extensively been studied, crucially, they are not smoke. In every context other than smoking, we human beings have always tried to avoid smoke. Even considering the addictive wonders of nicotine, it’s incredible we ever believed it was safe.
