Vaping is the inhale and exhale of vaporized liquid, this liquid is usually a mix of propelyene glycol, vegetable glycerin and flavourings
When combined with Nicotine it is a very effective way to help quit smoking.
There are two ways in which to inhale vapour and different devices will be suited for one of these methods.
MTL: Mouth to Lung
This is to replicate a draw like a cigarette, this is usually used for those new to vaping and is inhaled into the mouth and then into your lungs like a cigarette. This is used with higher resistance coils and lower power.
DTL: Direct to Lung
Usually for intermediate to advanced users, this type of draw is directly into your lungs and then exhaled quite quickly. Higher power and lower resistance coils are associated with DTL draws. Also the term subohm, with means the coil resistance is lower than 1.0 ohm.
How do vaping devices work?
All vaping devices work in the same fundamental way: A battery powers a coil (heating element) that turns the e-liquid into vapour. Vape devices come in all shapes and sizes, all doing the same job but in their own way.
