I have been wanting to try it but I thought I would ask before I do. I want to add a drop or two of Vanilla extract to my tobacco flavour. has anyone ever done that? there are concentrated fruit flavors, such as banana, strawberry ect. that I have in the house. The only thing that has prevented me from trying it is the oils in them. They are potato oil, alcohol, fusel oil. can you vape those?http://en.wikipedia.org/wiki/Strawberry
