I usually buy my flavorings from Lorann oils but I found this site and thought it interesting enough to order some from them. It is interesting that they say their flavors are so concentrated that they can be used for vaping (as in flavored E-cigarettes). It is also interesting and two of the flavors they sell are "Mary Jane" and "Marlboro Red"
