I don't know about any of that, but I do remember going to see rock concerts in the 80's, when I was a pre-18 teenager, and getting free samples of cigarettes that were being given out by the cig companies. I suspect they aren't as audacious nowadays in their attempts to hook kids.
Oh yeah! You mean those small packs of 5 cigs, I believe. I think Newport had a non-menthol brand (didn't go very far) like that. Anyone could just grab those samples, kids or not.
