12mg Nicotine

12mg is a mouth-to-lung strength, and a fairly firm one. It gives a definite throat hit, which is exactly what some people want and exactly what puts others off.

It belongs in a tight, higher-resistance coil rather than anything sub-ohm - at 40W a 12mg liquid would be genuinely unpleasant.

If you like the hit but find 12mg harsh, a 20mg nic salt is stronger on paper and noticeably smoother in practice. That is the trade salts were invented to make.
