We've had cigarettes for years ingame, we swear, we have drugs and alcohol ingame. Why are we acting like it's a problem now? This isn't even related to the topic. These threads are starting to get ridiculous now with some of these requests.
Now, for stuff actually pertaining to the suggestion at hand. I think that the number of cigarette packets are fine and offer a great variety for different species. The rolling paper? I think that should be reduced to a singular brand because, as Kaed said, there are no mechanical differences AND you cannot give much roleplay from different types of rolling paper. Even with different cigarette packs, you could link it to corporate loyalty, cost, or feeling- not much you can do with rolling packs.
I actually agree with the chewing tobacco bit- it can smell and unlike normal gum, it has to be spat out and take up place and look extra disgusting because it's tobacco and I think that's something a place the Aurora wouldn't want. Some other, more lowlife NT facility? Definitely would allow, but the Aurora? No. I don't think the Aurora would allow tobacco past a cigarette.
