So I order some V4L nabacco juice but when i fill it up in a cartomizer and vape it. The thoart hit seems to be alittle rough. I'm using a 11mg wow mango but the lable says nabacco on it but mango doesn't come in nabacco, and the other one is OJ in nabacco in 18mg. I have one in a wash clean cartomizer, and the other was just refill from a different flavor carto. What is the difference between V4L nabacco vs PG/VG?
