<\/p>\n\n\n\n

  1. There is no tobacco in e-cigarettes<\/strong><\/li><\/ol>\n\n\n\n

    Vaping liquid is made of a mixture of vegetable glycerin and propylene glycol, to which nicotine and artificial flavours (such as tobacco or fruit) are usually added.<\/p>\n\n\n\n

    Because vape liquid is heated but not burnt, the health risk from long-term use of e-cigarettes is \u201cunlikely to exceed 5% of the harm from smoking tobacco\u201d [1].<\/p>\n\n\n\n

    2. Vaping does not cause death, \u201cPopcorn Lung\u201d or \u201cE-cigarette- or vaping product-associated lung injury\u201d (EVALI)<\/strong><\/p>\n\n\n\n

    Health Canada states \u201cthere have been no deaths<\/a> reported as a result of vaping-related illnesses in Canada\u201d and \u201cthere have been no reports of popcorn lung<\/a> occurring due to vaping.\u201d.<\/p>\n\n\n\n

    \"\"
    The US “EVALI” outbreak lasted from June to December 2019. It is now over.<\/em><\/figcaption><\/figure>\n\n\n\n

    The 2019 USA outbreak of severe acute lung injury labelled as EVALI was caused by Vitamin E added to bootleg cannabis products, not legal nicotine vaping [2].<\/p>\n\n\n\n

    3.Vaping is more effective at getting smokers to quit than conventional nicotine replacement therapy<\/strong><\/p>\n\n\n\n

    In a randomized control trial, the 1-year abstinence rate was 18.0% in the e-cigarette group, as compared with 9.9% in the nicotine-replacement group (P<0.001) [3].<\/p>\n\n\n\n

    A Cochrane meta-analysis of 61 studies concluded: \u201cFor every 100 people using nicotine e-cigarettes to stop smoking, 9 to 14 might successfully stop, compared with only 6 of 100 people using nicotine-replacement therapy\u201d [4].<\/p>\n\n\n\n

    4. Switching from smoking to vaping saves lives and improves health<\/strong><\/p>\n\n\n\n

    Replacing cigarettes with e-cigarettes would result in 1.6 – 6.6\u2009million fewer premature deaths, with 21-87 million fewer life years lost in the USA alone [5].<\/p>\n\n\n\n

    In a five-year study of COPD patients, switching was associated with fewer exacerbations, improved lung function, and a longer six-minute walking distance [6].<\/p>\n\n\n\n

    5. Teen vaping has not led to an increase in teen smoking<\/strong><\/p>\n\n\n\n

    While teens who experiment with one form of inhaled nicotine are indeed likely to experiment with the other form, NYTS data shows that smoking rates have declined more rapidly in the USA since vaping became popular. Over half the teens who were vaping in 2019 had quit by 2021, suggesting that vaping is a fad, not an addiction.<\/p>\n\n\n\n

    Teen smoking is associated with anhistoric decrease in teen smoking. There is no “Gateway Effect”.
