How long do the juices last in a cart on average ? Like how many normal size pulls ?
Well, the size of everyone's pulls varies. But I"d say I go about 15 minutes of vaping before I need to top off the cartridge. However, don't let the cartridge go completely dry. Just top off when you start tasting too much of the poly filler -- you'll know the taste when you taste it.
Also, don't be discouraged if you find yourself coughing at first. Vapor isn't the same as smoke, and you may have to adjust a bit, just like you did when you started smoking cigarettes.
Oh yeah, and welcome to ECF!
