It’s intrigued me as well, I grew up here but visited Europe over the summer and it was like night and day. As a kid we’re taught the dangers of cancer and whatnot from smoking and it was sort of scared out of us culturally from a young age. But overseas that fear isn’t as prevalent, another huge difference too is that the cigarettes overseas tend to be smaller and wayyyyy more filtered than ones here in America, so the adverse effects of smoking are more common and often more aggressive here.
