What is the difference between mouth-to-lung and direct-to-lung vaping with e-cigarettes?

Users who are new to e-cigarettes may often hear others talking about mouth-to-lung (MTL) and direct-to-lung (DTL) vaping, and may not be able to distinguish between the two. In fact, these are the two most common inhalation methods for e-cigarettes, and different inhalation methods can bring users different usage experiences.

How to do mouth inhale with an electronic cigarette?

Mouth-to-lung vaping is similar to the smoking technique we use in our daily lives, where the gas is first inhaled into the mouth before being drawn into the lungs. The atomizers commonly used for MTL vaping have a higher resistance of 1 ohm or more, and the mouthpiece is generally narrower than those used for direct-to-lung vaping. The power of the device is usually within 15W. To match these devices, users will also choose e-liquids with a higher proportion of propylene glycol (PG) to create a similar inhalation experience to smoking.

Mouth-to-lung vaping produces smaller clouds with a stronger throat hit, and users should take their time to enjoy it slowly. When inhaling, it feels similar to smoking a cigarette, with the vapor first entering the mouth and the flavor filling the mouth cavity. After a pause, the vapor then enters the lungs and is exhaled, providing a different flavor and a satisfying experience.

Compared to direct-to-lung vaping, the vapor from mouth-to-lung vaping lingers in the mouth for a longer time, so users who choose this method also tend to have a more subtle and delicate taste experience. Cigar and cigarette users generally use mouth-to-lung vaping, so most users who switch from smoking to e-cigarettes also choose to use the mouth-to-lung method.

How to do lung inhale with an electronic cigarette?

Lung inhale refers to the inhalation method where the vapor is not held in the mouth but directly inhaled into the lungs, similar to taking a deep breath. The dense vapor instantly fills the lungs, providing a sensation similar to using a hookah. This method is suitable for low-resistance atomizers, which allow for a larger amount of vapor to be inhaled in one go, resulting in significantly larger clouds of vapor when exhaled. This can provide users with a more intense and satisfying flavor experience, but it is important to reduce nicotine concentration and increase VG content to achieve larger vapor production.

Lung inhale is like a sudden explosion of intense, thick clouds of vapor that directly enter the lungs without staying in the mouth, before being exhaled, with the smoke swirling around in a mesmerizing way.

In summary, mouth inhale is like sipping red wine, to be savored slowly, while lung inhale is like drinking beer from a large bottle, quickly and intensely.

It is worth noting that new users of electronic cigarettes are advised to start with mouth inhale as lung inhale can cause choking if not done properly. Once you are more experienced, you can try lung inhale. Whether you prefer mouth or lung inhale, it is best to find what works for you.
