"Vapes leading to smoking" headlines are always WILDLY misleading. If you look at the surveys they use to create those responses, they always include exceptionally low-frequency cigarette use. (think, "have you smoked a cigarette in the last month"). This captures habitual vapers who, once in a while, can't get a hold of vape juice, and buy a pack of cigarettes.

Like, maybe my vape runs out of battery while I'm out for a night of clubbing with my friends. Nicotine and alcohol get along like a house on fire, and I've got a bit of a habit, so I pop into a gas station. They're not selling vapes, they're selling cigarettes. So I buy a pack of cigarettes, smoke a couple, and probably end up ditching the pack once I get a hold of a charger because vapes are better in every way.

I'm in an age bracket where a lot of people picked up a nicotine habit in college, and literally zero of couple dozen users I know stopped vaping and started smoking cigarettes. Vaping's cheaper, more comfortable (no burning your throat), safer (not to be confused with "healthy"), and doesn't make you stink. And the single biggest reason nobody switches from habitual vaping to habitual smoking is that smoking provides less nicotine. You need to be slurping down cigarettes to get a similar hit.
