E-cigarettes are electronic products that mimic cigarettes and have the same appearance, smoke, taste and feel as cigarettes.
E-cigarettes are mainly composed of four parts: e-liquid (containing nicotine, essence, solvent propylene glycol, etc.), heating system, power supply and filter. Through heating and atomization, aerosols with specific odors are produced for smokers to use.
E-cigarettes are harmful to public health and are not a means to quit smoking. They must be strictly controlled to prevent them from harming young people and non-smokers.
