Hoping someone can help me out here.... I read in another post about being able to buy 100% VG at your local pharmacy to help increase vapor production and to thicken some of my juice. But when I went to my local CVS and asked them for Vegetable glycerin they looked at me like I asked for a crack pipe. I saw a person call the 100% VG something else, like UBS something or another but could not get back to that post to see it exactly....can someone help that has bought this at a local drug store???
