What is Sub Ohm Vaping?


The first e-cigarette was invented by Chinese pharmacist Hon Lik in 2003.

Since then, vaping has grown into a multi-billion dollar market with hundreds of devices and thousands of flavors to choose from. Sub ohm vaping, for example, requires a specific type of device and delivers a different experience than traditional vapes.

Sub ohm vaping is not for the inexperienced. But when you’re ready for big clouds and intense flavor, it might be worth considering. 

Keep reading to learn more about sub ohm vaping and decide whether it’s something you’re ready for.

What Is Sub Ohm Vaping?

A traditional vape has a resistance between 1.5 and 3 Ohms. A sub-ohm device has significantly less resistance. In fact, sub ohm means “below 1 ohm of resistance”.

What does that reduced resistance mean for your vaping experience? It means that the atomizer coil can heat up more quickly. And that means more vape juice can be vaporized, producing bigger clouds of vapor and intense flavor.

Sub-Ohm, MTL, and DTL

Vaping devices are designed to be inhaled in one of two ways. With a mouth-to-lung (MTL) device, the user draws vapor into the mouth and then inhales that into the lungs. These feel similar to smoking a cigarette and they don’t produce that much vapor.

With a direct-to-lung (DTL) device, you inhale the vapor from the device directly into your lungs and you exhale right away. DTL devices are sometimes called sub ohm devices. They’re larger than MTL devices, use higher temperature settings, and produce a lot more vapor and flavor.

Why Do People Sub-Ohm Vape?

One of the big draws of sub ohm vaping is the size of the vape clouds you can produce. If you want to get into vape tricks, this is the kind of vaping device you’ll require.

Sub ohm vaping also produces a lot more flavor. This is simply because you’re inhaling a lot more vapor than you do with higher resistance devices.

As a result of the reduced resistance, sub ohm vaping device creates a stronger hit, too. For this reason, they’re best left to advanced vapers.

Should Beginners Try Sub-Ohm Vaping?

Sub ohm vaping isn’t recommended for beginner vapers. The low resistance coils require a lot more power to use. They also create a lot more vapor than traditional devices, which can make them harsh on the lungs.

Sub ohm vaping also isn’t recommended for people who are trying to quit smoking. Juices with high nicotine levels can be very harsh in a DTL device. They also don’t provide the same throat hit many smokers are looking for.
