Mouth to Lung vaping (commonly known as MTL) is in simple terms the same as how most people inhale a cigarette. You suck the vape into your mouth and then inhale it into your throat or lungs.
MTL vaping does not focus on creating big volumes of clouds. Instead, flavour and nicotine is what is produced, in order to deliver satisfaction. Usually having a setup that outputs at 15 Watts or lower. There are three main benefits to using MTL vaping; one is low-profile vaping, which allows for less visible vapour. Secondly, we have convenience, since the devices are on average smaller, less vape juice is consumed over time. And finally, we have savings, as MTL devices in general, are more affordable than Sub-Ohm devices and cheaper to maintain.
A highlighted disadvantage for few MTL users is that since the devices are low-powered, users might not get a satisfactory nicotine lever, and ultimately higher nicotine strength will cause harshness on the throat area. This can be easily adjusted by adopting Nic Salts, as they can have high nicotine content in their e liquids, but avoid throat harshness altogether.
