Despite having never smoked a single cigarette in my life, I have an intensely strong reaction to a very specific brand. Early in high school I met my first crush, and one summer learned that she liked me back. She was my first everything. And the scent of a lot of that teenage exploration was the awful but sweet smell of her parents’ basement, stained with that brand of cigarette.

I have no clue what brand it is. But if I ever smell it in public I am teleported back there and find myself aching terribly with youthful nostalgia.

I don't think I ever saw anyone identify a brand just by the smell. it's impossible. most brands from the same parent company are made at the same factory from the same batch of the same chemical-soaked tobacco pulp. it's just the filters and packages that are different. when I smoked, chesterfields, l&ms, pall malls, winstons, parliaments, etc, all tasted and smelled the same to me. only the cheapest godawful local brands smelled different than the rest.

You must have clue! If there is one thing tobacco companies are brilliant at it is branding. Why else would I have smoked Marlboro (and I am English) for all those sad, sad years.
