I'm interested in trying out my own mixtures. I've been looking over the thread dedicated to making your own juice (http://www.e-cigarette-forum.com/forum/diy-e-liquid/5066-eliquid-recipes.html), but one thing I can't seem to find is where to get liquid nicotine. I know a supplier that sells 16 oz of VG for $12.99, and LorAnn has some tempting flavors, but where do I get nicotine????? Do people just use flavorless juice for this?
