卷烟 literally means 'rolled smoke' — 卷 (juǎn) means 'to roll' or 'to coil', and 烟 (yān) means 'smoke' or 'tobacco'. Together, they refer specifically to factory-made cigarettes: slender, cylindrical tobacco products wrapped in paper, designed for smoking. Unlike traditional hand-rolled tobacco or cigars, 卷烟 denotes the standardized, mass-produced kind commonly sold in packs.

This term is formal and neutral in register — it appears in public health announcements, government regulations, product packaging, and news reports. While colloquially many speakers say 香烟 (xiāng yān) or simply 烟 (yān), 卷烟 is the official, technical term used in legal, medical, and statistical contexts (e.g., cigarette taxation, smoking cessation programs, or epidemiological studies). It carries no inherent positive or negative connotation linguistically, though context often implies health-related concerns.
