I have news from my perspective as a former smoker who took many years to finally quit for good: If thoroughly addicted, a smoker will smoke, no matter how limited the flavor selection. This applies to smoking places, too. No smoking within 10 feet/25feet/100 feet? No problem! Have smokes, will travel. The good news is that kids, "beginner-smokers" take a couple of years to become teeth-gnashingly addicted to any substance, making the act of quitting a bit easier with LOTS of support and education.
What's working against recovery especially now is that kids feel in their bones the horror of environmental collapse and threat of mass extinction - including their own. What's to be hopeful for these days, eh grownups?
