In short: Desomorphine is a potent opioid that was once a legitimate medical tool for severe pain. Today, it is known as "Krokodil," a substance so toxic that it causes necrotic skin lesions and gangrene. Its journey from a refined pharmaceutical to a

First discovered and patented in Germany in 1920, desomorphine was synthesized in the U.S. in 1932 and patented in 1934. For managing intense agony, this substance was marketed as Permonid across Switzerland, Austria, and Germany. However, medical use was terminated in 1981 because its benefits were outweighed by severe side effects, including significant respiratory depression, hypotension, and urinary retention. From a chemical perspective, desomorphine represents a morphine derivative featuring a reduced 7,8 double bond and 6-hydroxyl group. It is roughly ten times more potent than morphine when administered intravenously or intramuscularly. While it offers faster onset and less nausea than morphine, animal studies revealed it also possesses increased toxicity, higher levels of sedation, and increased digestive activity compared to its parent compound. The drug's modern notoriety stems from "Krokodil," a highly impure variant produced clandestinely.

Because of easy access to over-the-counter codeine in Russia until 2012, users began synthesizing it using hazardous materials like red phosphorus from match strikers, iodine, gasoline, and battery acid. These illicit producers often fail to remove toxic solvents or adjust the pH, which can drop as low as 3—as acidic as lemon juice. Injecting these contaminants causes rapid tissue death, phlebitis, and even bone infection, leading to the nickname "zombie drug" due to the resulting scaly, crocodile-like skin. While the drug was declared illegal in Russia in 1998, its use persisted due to the simplicity of its synthesis. Estimates suggest around 100,000 people used Krokodil in Russia and 20,000 in Ukraine at its peak popularity.
