 Another illicit source is morphine extracted from extended-release morphine products.Chemical reactions can then be used to convert morphine, dihydromorphine, and hydrocodone into heroin or other opioids [e.g., diacetyldihydromorphine (Paralaudin), and thebacon].Other clandestine conversions—of morphine, into ketones of the hydromorphone class, or other derivatives like dihydromorphine (Paramorfan), desomorphine (Permonid), metopon, etc., and of codeine into hydrocodone (Dicodid), dihydrocodeine (Paracodin), etc.
