General information regarding puffing techniques while vaping
When vaping, a distinction is made between two puffing techniques:
Moderate vaping (mouth-to-lung)
The vapor from an e-cigarette is first collected in the oral cavity for the entire duration of the puff and then inhaled
into the lungs� This puffing technique is referred to as moderate, mouth-to-lung vaping and is just like smoking a
tobacco cigarette� To achieve this, there must be a noticeable resistance when puffing on the e-cigarette� Evapora-
tor heads that support this puffing technique in the moderate range (resistance usually > 1 ohm) are often referred
to as MTL (mouth to lung) heads� (Other abbreviations include ML and M2L�)
Sub-ohm vaping (direct lung inhalation)
While puffing, the vapor of an e-cigarette is directly inhaled into the lungs� This puffing technique is referred to
as sub-ohm vaping with direct lung inhalation� To achieve this, there must be low puffing resistance and a strong
air supply to the evaporator head� Both have a positive effect on producing large quantities of vapor� Evaporator
heads that support this puffing technique in the sub-ohm range (resistance usually < 1 ohm) are often referred to
as DL (direct lung) heads� (Other abbreviations include DTL and D2L)
