I've had some 6mg juices that haven't burned my throat but most do... I have bought the same flavors in both 6 and 3 and 6 will burn 9 times out of 10 and the 3 doesn't. I feel nothing when vaping a 3 mg juice thought. I've also tried different vg/pg mixes and different wattages from 30 watts all the way to 100 watts and that doesn't seem to make a difference. I'm typically run a dual 3mm fused Clapton build in a dead rabbit, or the same build on a drop rda. I need some help on identifying the issue here.
