Our narcotics kit comes with 4 odors in total: Cocaine, Heroin and Meth plus a fourth odor that you choose. Check out the Flavors drop down tab to select your fourth odor. Our narcotics odor prints are 4in in length and are equivelant to 20g of target material. All odors are safe to handle and don't require a DEA license to purchase. Odor will cleanly emit over 6-12 months depending on usage. All orders are made to order so allow 2-3 weeks lead time.
