Nicotine shots can come in a variety of ratios and strengths. They can range anywhere from 3mg all the way to 20mg, flavourless to menthol, with a choice to choose the PG/VG ratio to suit your current Short-Fill E-Liquid. The short fill bottle has a large enough bottle space should the user choose to add a nicotine booster shot.
By adding a 10ml nicotine shot containing 18mg into a 50ml short fill, would result in a 60ml short fill containing 3mg (0.3%) of nicotine.
