However, the increasing popularity of krokodil is likely related to the ability of lay persons (with little or no chemistry training or equipment) to chemically produce a heroin-like opiate drug, at home, using readily available solvents and internet-obtained 'recipes' which are posted on drug forums and chat rooms. By using the available, though dangerously unreliable, instructions, users are converting the much cheaper and easier-to-obtain drug codeine, which is often available over-the-counter or with an easily obtained prescription, into desomorphine, a much stronger opiate. With the street price for heroin or oxycodone much higher than the cost of the codeine and chemicals, users manufacture krokodil for a cheaper, comparable high. However, lacking proper equipment, training, and testing equipment, users are extremely unlikely to produce desomorphine in a pure form at home, and as a result end up injecting a highly impure mixture of codeine, desomorphine, and the toxic chemicals used in the crude reaction such as lye or acetone. While studies are as yet unavailable of various samples of krokodil seized in different regions, it is likely that the drug is in fact not a single chemical, recipe, or 'designer' drug, but rather the medical symptoms caused by the injection of toxic chemical used in a variety of 'home-bake' drug synthesis methods, although traditionally such processes are used by methamphetamine home producers.
