You can try to vape that, but I promise you, that will be all you taste and smell for a couple of days!
Pour that down the drain. Do it now.
Most flavors that are extracted such as tobacco and coffee have a tendency to be insanely strong. I use a Black n Mild flavor from TFA that at 1% is still just a touch on the strong side but nice nonetheless.
I've never come across a standalone tobacco. Every one of them needs other flavors to bring them out and make them shine. Look for recipes, a plethora of eliquid recipe sites can be found with a simple Google. Use those sites, try their recipes for the flavors you have on hand.
For me, I would use your Havana at 1%, then add 3% vanilla, 5% caramel, maybe 3% chocolate, and for laughs, probably 3-5% peanut butter for an interesting yet savory vape. There is a flavor enhancer that TFA makes called "Smooth", it will cut the harsh edges off the tobacco flavor. Tobacco Magic is another one, I disremeber who makes it offhand. It's helpful.
Make your juices in trial batches without nicotine while experimenting with flavors. I do 3ml at a time while testing. Flavors, PG, and VG are cheap...nic is not. Get your flavors down pat, then add nic. Don't forget that nic adds throat hit and a peppery flavor, compensate for that mentally as you work out your flavor percentages.
When making juices for other people, unless they specifically ask, don't go over 1.8% nic (18mg/ml). Nicotine is harsh, and some people may be sensitive to higher concentrations. A friend of mine recently had me try his Red flavor at 36 (!) mg/ml. Took me a minute to find my eyes and pop them back in.
