Vaping does not smell the same as cigarette smoking. E-vaping liquids come in different smells and flavors that are pleasant to the nose. It is not as irritating as the ones you smell from cigars. The aroma will not pass onto clothes like how cigarettes can badly leave odor to clothing. Your clothes cannot easily absorb the scent of vape liquids. When you are in an enclosed area without ventilation and a vape, the scent can transfer. It can linger on your clothes, allowing people to notice you vape. The smell of vape can linger on someone right after smoking e-liquids. You can smell when someone is vaping. The scent of vape can stay for a little while, especially in a room without ventilation.
