With coil resistances lower than 1 Ω, vapers can experience Direct Lung (DL) inhalation, also called DL Hit. It consists in inhaling the large quantity of vapor produced by the single, dual or even triple coil atomizers and more powerful devices (up to 200 W) and in exhaling big clouds of vapor. The clouds blowed by DL vapers are a pretext to try what the specialists call vape tricks, like rings, vortices, O’s and other tornados…

Formerly reserved to the underground vaping culture, vape tricks now come to daylight, and trickers are popularized though social media or during vape meets and other events. Their discipline is half way between sport and art. Trickers get sponsorized by e-juice brands and participate in contests. Cloud chasing, the art of doing big clouds, is also the object of competitions.

Do you blow O’s?

As opposed to the more traditional Mouth-to-Lung (MTL) vaping style, an unexpected outcome of the increasing popularity of DL inhalation is the lowering of the nicotine strength of the e-liquids used for tricks. The vendors notice that customers who invest in subohm mods also purchase more liquid but at a lower strength.

From the 20 mg/ml maximum allowed in Europe (36 mg/ml in the USA) and generally used by beginners, the average nicotine strength decreases to around 12 mg/ml for experienced vapers with third generation mods. For trickers, it is not uncommon to see nicotine strengths used as low as 3 mg/ml and down to zero.

Less choices in stores

The drawbacks are that some brands that specialize in those types of e-juices decrease the offer of nicotine strengths they propose, aided by the burdensome procedures and non negligible fees for each flavor and strength in their range. The most penalized are the vapers who do not share the keen interest of chasers and trickers.

  1. Big time drawbacks for us long time mouth to lung vapers. Don’t forget that the hobbyists have pushed for bigger clouds and lower resistance coils for about 3 years. Now the market is flooded with close to 300ish sub ohm tank varieties and the traditional mouth to lung vapers have very few choices. Smokers usually like to simulate smoking which in most cases is done mouth to lung style. Smokers also need much higher nicotine to get the satisfaction of smoking. The industry has lost its way.

    • That may be, but shops can add/increase NIC levels if it is not enough. A few times I have bought 0 nicotine juices and had them add nicotine because my usual strength was not in stock… I really don’t see the lower Nic strengths as an issue.

      • Since August 8th the FDA says you can no longer mix or add nicotine to juices at a store. Most of the new juice lines don’t even make juice above 12 mg and many only up to 6mg. This will not be enough to satisfy smokers. We need smokers and they need us. We are catering to the hobbyists when we need to cater to the smokers!

  2. Hang on, that’s not quite right about sub-ohm.
    I vape at 0.5 Ohm to 1.0 Ohm (so sub-ohm), in drippers with a 1mm airhole, and I am strictly M2L.
    As power goes up, sub-ohm will become more and more meaningless.
