Can anyone clear up my glycerine confusion?? What kind of glycerine would be in the glycerine I buy at the pharmacy? The bottle does not state origin. Is it vegetable? or other? I bought it and after diluting 1/1 with water I then drip 2 drops of e-liquid, and 1 drop diluted glycerine. Makes MUCH better vapour, but it seems vegetable glycerine is the choice of the seasoned e-smoker. Am I damaging anything, including myself by using this type of glycerine?
