Cigarette alternatives contain multiples of nicotine. Addiction thus develops more quickly
“If I completely simplify it to a burn-burn fact, then what doesn’t burn is really less harmful to humans. But at the same time, alternatives to cigarettes (e.g. IQOS) contain other harmful substances and up to ten times the amount of nicotine that the smoker is used to. Addiction to them develops significantly faster,” says addiction specialist Michal Miovský.
