"E-juice" and "e-liquid" are often used interchangeably to refer to the liquid used in electronic cigarettes (e-cigarettes) or vaping devices. There is no significant difference between the two terms, and they both refer to the same product.
E-juice or e-liquid is a mixture of propylene glycol (PG), vegetable glycerin (VG), flavorings, and sometimes nicotine. PG and VG are used as a base to create the vapor that is inhaled when using e-cigarettes or vaping devices. Flavorings are added to create different tastes, and nicotine may be included in some e-juices.
Some manufacturers may use one term over the other, but they both refer to the same product. It's important to note that while e-juice or e-liquid may be less harmful than smoking cigarettes, they still pose health risks and can be addictive due to the presence of nicotine.
