There is no denying the fact that smoking is unsafe and highly dangerous to health, but if you are really looking for a safer choice, e-cigs or vaping is a far better option. E-Cigarettes use a battery controlled system to adjust the quantity of flavoured vapour to suit your needs. The decision to choose the correct tank stems directly on your preference of inhalation. When you light a smoke, and inhale, do you inhale the smoke directly into your lungs or do you inhale into your mouth and then a second inhale into your lungs? Once you know this, you can choose the right tank J
Mouth to lung
Mouth to lung tanks consist of tanks that have a coil resistance of over 1 ohm. Tanks that accommodate this style of coils are the Aspire Nautilus and BVC series coil systems like the Aspire K1. Mouth to lung inhalers prefer these tanks as they have a tighter draw and vapour production similar to a cigarette. This is the closest experience you will get to a cigarette.
The method involves directly inhaling the vapour directly into the lungs. Tanks that accommodate to this style of vaping consist of coils that have a coil resistance of less than 1 ohm. The vapour production is noticeably larger, the airflow has substantially less resistance, and vapers notice better flavour from these styles of tanks as well. These tanks are also known as sub-ohm tanks. They include models like the Kanger Subtank range, Aspire Triton and Atlantis and Sense Herakles to know a few. You will find most new tanks on the market these days are sub-ohm tanks due to a increased level of popularity.
There is no right or wrong method, it all comes down to preference :)
