E-liquids use one of two nicotine forms. The right one depends mostly on your device.
The traditional form. Pairs with higher-power setups, produces more vapor, and gives a stronger throat hit at higher strengths.
A smoother form that carries higher strengths comfortably, which is why it suits compact, low-power pod devices.
Rule of thumb: bigger tanks and mods lean freebase; small pods lean salts. Staff can match liquid to your hardware.
