With NPCs being able to smoke, isn't it time to give the players that ability as well? With tobacco products already being in the game, it shouldn't be too much of a stretch to expand on that a little. In the story, we live in an age of poverty, greed, violence... destruction. Indeed Shadowbringers is about genocide itself, so why should we fear a little virtual tobacco when the stakes are so high? This being a video game, it would purely be a safe aesthetic choice should the player wish to choose to partake in it.
As many players have put it, the true endgame is glam, and smoking can be an extension of that.
