Tobacco giant Philip Morris International has been lobbying federal government MPs to overturn Australia’s ban on vaping, but its efforts remain hidden from public view due to fundamental flaws in the lobbyist oversight regime. Philip Morris, owner of six of the world’s 15 biggest cigarette brands, is in the midst of a significant push to grow global sales of its vaping products, predicting they will bring in $17bn to $19bn by 2025, roughly 42% of its total revenue.
