Electronic cigarettes are mainly divided into PG, VG, flavors, and nicotine. PG and VG belong to healthy food additives. Flavors and fragrances mainly provide various flavors. Nicotine provides addiction and larynx. What's the reason for the first dry electronic cigarette throat? The main reason is PG, also known as vegetable glycerin. When using electronic cigarette, it will produce smoke because of it. Water absorption is one of its characteristics. When we pump repeatedly, it will cause the water inside the mouth to be absorbed. The more we pump, the more we absorb, so it will cause our throat to be very dry. The smoke produced by electronic smoke and paper smoke are two different forms of things. The oil of electronic smoke atomizes the mist like water vapor, while paper smoke burns to produce smoke. In the initial stage, when you adapt to electronic smoke, you can use the way of "running smoke", fast smoking and fast spitting, and slowly adapt to the smoke produced by cigarette oil.
