I just ordered some flavors from Lorann and saw that they had glycerine. I figured for $2.99 I'd go ahead and order a 4-ounce bottle, but I know I've read somewhere that you should only buy the stuff that's pharmaceutical grade. Does anyone know if the Lorann glycerine is okay to use for mixing up e-liquid? If I need to get it from a pharmacy, that's fine, because I'll use the Lorann glycerine to make candy or something (they say that's what it's for....).
