Cigarette smoke was a nostalgic smell for Luffy. It reminded him of when he was little; of the smell of the patrons in Makino's bar; of the smell on Ace and Sabo when they occasionally passed cigarettes between themselves, leaving him out.
Luffy himself didn't smoke very often. It burned the back of his nose and made him cough. But the peppery scent of tobacco was safe and comfortable and he loved to sit in Sanji's lap while Sanji smoked. Smelling the scent of it lingering on the ship always meant that Sanji had been there, and made him smile.
