Clouds of Harm: The Health Impact of Youth Vaping in Malaysia

E-cigarettes (EC), also known as vape pens, e-cigars, or vaping devices, produce an aerosolised mixture that contains flavoured liquids and nicotine, which users inhale. These electronic nicotine-delivery systems come in a wide variety due to differences in nicotine concentrations, e-liquid volumes, carrier compounds, additives, flavours, and battery voltages. Each EC device typically operates using a standard system, which includes a rechargeable lithium battery, a vaporisation chamber, and a cartridge. The lithium battery powers the vaporisation chamber, which contains the atomiser. Users inhale through a mouthpiece, and the airflow activates a sensor, initiating the atomiser to deliver nicotine to the lungs. The liquid nicotine stored in a small cartridge is then vaporised and inhaled.
