Yes, you could add flavor. I make my own juice. You might consider making your own as well. You can make the juice EXACTLY like YOU like it. No more waiting a week for it to arrive only to be disappointed with the flavors. Also if you get a craving, you can just whip it up right then. It's the best thing I've done. It saves loads of money and it's super easy to do. Some complex flavorings wI'll take a bit of practice but that's the fun of it. By making your own juice, you can tweak it to your own personal taste. It's start up is fairly easy. You simply need pg, vg, and flavors.I get giant jugs of pg and vg online for around 17 dollars.the nicotine is the most expensive coming in at about 35 dollars for a large jug and 20 for asmall jug. Flavors are around 1.50 to 3.00. It's fun and very economical.
