ELECTRONIC CIGARETTE: DIRECT OR INDIRECT INHALATION?

Are you interested in the world of vaping and considering switching to electronic cigarettes  to quit smoking ? It’s a very good decision! To help you take the plunge optimally and choose the right vaping material, Nicovip explains the difference between direct inhalation (DL) and indirect inhalation (MTL) .

Direct inhalation (DL) and indirect inhalation (MTL): definition

To begin with, what is direct inhalation (DL) and indirect inhalation (MTL) ? These terms that you will find on the sheets of e-cig kits and clearomizers correspond to two ways of vaping with an electronic cigarette.

Direct Inhalation (DL): also called Direct Lung in English. It is an inhalation method that passes the vapour directly to the lungs. Shisha and hookah smokers use this type of draw.

Indirect Inhalation (MTL): also called Mouth To Lung in English. It is a two-step method of inhaling steam: first into the mouth, then into the lungs. Cigarette smokers inhale smoke this way.

Which inhalation method for which type of vaper?

If you’re a smoker looking to quit , you’re used to Indirect Inhaling (MTL) with a tight draw. To maintain the same sensation with an electronic cigarette as with a tobacco cigarette, you must turn to an e-cig model designed for indirect inhalation . An MTL electronic cigarette is above all an MTL clearomizer, with resistance for an e-cig of 1ohm or more. It is this high resistance, associated with a reduced airflow (air flow), which gives this inhalation in two stages, as with a cigarette. 

If you are already a vaper or a shisha smoker and you want to turn to cloud chasing , that is to say the production of vapor in a very important way, you can experiment with direct inhalation . This drawing method allows you to obtain real waves of steam! The shisha style vape, which produces streams of vapour, is linked to the use of a powerful electronic cigarette, with very low resistances. A DL clearomiser has a giant airflow so as to be able to suck in as much air as possible and thus create a very thick vapour.  

Direct inhalation (DL) and indirect inhalation (MTL): which electronic cigarette?

Direct inhalation (DL) : choose a powerful electronic cigarette, sub-ohm resistors (less than 1 ohm), a clearomizer with a large airflow system and a short and wide drip tip. Not to mention High VG or Full VG e-liquid ! For the more seasoned, there are very powerful boxes designed for power vaping and reconstructable atomizers . This type of setup must be handled with care and requires solid knowledge to make the adjustments. The vapor obtained is extremely abundant and hot!

Indirect inhalation (MTL) : opt for a low-power electronic cigarette (pod or box) and high-value coils (more than 1 ohm). If it is equipped with an airflow, the clearomiser of your e-cig will offer you the possibility of further restricting the draw or not. Prefer e-liquid rich in propylene glycol or balanced in PG/VG for the vape in indirect inhaling. The vapor will be less abundant but the hit and the flavors will be even more present!

Note that there are also versatile electronic cigarette models , which are intended for both MTL and DL vaping !

If the vape tricks made with vape material for direct inhalation are trendy, we must not forget that the e cigarette is above all designed to quit smoking. If you are new to vaping because you plan to quit smoking, don’t go for advanced gear. An electronic cigarette with a high vapor rate will be of no use to you if it does not meet your needs to quit smoking! Similarly, vaping should not be seen as something fun, especially for the youngest. If you don’t smoke, don’t start vaping, especially not with nicotine.
