Maybe I'm just an old geeser but when I went back to grad school I was absolutely shocked at how many people vaped, and it seemed to have been because they started smoking flavored vapes. People would go to a party, either in high school or college, and the party would be permeated by some sweet smell. Curious kids/people would investigate, try vaping, and eventually get their own, becoming addicted.

As far as I can tell, banning flavored vapes has had a significant impact on reducing vaping/smoking new users, which is the ultimate goal. People who are currently addicted should primarily be motivated to quit, not find better tasting alternatives
