It's not nearly as massive as the "legit" tobacco industry. If it was that big an issue, people would be smoking everywhere. And as I mentioned it's obvious how much more people are smoking in Europe compared to here.
So the point stands, that in absolute terms, smoking is way down. Your average person doesn't want to buy cigarettes from their local drug dealer.
I mean last week it was all over the news that Mattel and OpenAI made a deal to put chatgpt in toys such as Barbie.
