An electronic cigarette comprises at least one touch sensor, a microprocessor, and a light-emitting module. A control method comprises when a user touches the touch sensor, the touch sensor is triggered to generate an electric signal and transmit the electric signal to the microprocessor; the microprocessor controls the light-emitting module to emit a light on the basis of the electric signal transmitted by the touch sensor. The electronic cigarette light emission control method facilitates the user to find and use the electronic cigarette in the dark. Illumination with the light emitted by the electronic cigarette facilitates the user to walk in the dark, and, additionally, it facilitates the user to learn the power level of the electronic cigarette, while power saving is allowed by decreasing the intensity of light emission gradually.
