Opioids are drugs that relieve pain. There are different types of opioids available, including those made from poppy plants, such as morphine, and synthetic opioids, such as fentanyl.
When used as prescribed, they can be very effective at treating pain that’s not relieved by other pain medications, such as acetaminophen.
Opioids work by attaching to opioid receptors in the brain and preventing pain signals. They also boost feelings of pleasure, which is why they’re addictive.
The misuse of opioids has reached epidemic proportions. Every day, 130 people die from an opioid overdose in the United States, according to the
Desomorphine is an injectable derivative of morphine. You may have heard of it by its street name “krokodil.” It’s often referred to as a cheaper substitute for heroin.
Its street name comes from one of its many toxic side effects. People who use krokodil develop scaly, black and green skin that resembles crocodile skin.
Krokodil is the Russian spelling for crocodile. It goes by a few different names and spellings, including:
- alligator drug
It was first introduced in Russia in the early 2000s. It’s made by synthesizing desomorphine from codeine and mixing it with other additives, such as:
- hydrochloric acid
- paint thinner
- lighter fluid
- red phosphorus (matchbook striking surfaces)
These dangerous additives are likely the cause of its notorious side effects.
Russia and the Ukraine seem to be most affected by the drug, but there have been
The use of desomorphine was first reported in 1935 as a treatment for pain caused by trauma.
The drug was found to be a more potent pain reliever than morphine with a shorter duration and less nausea. Doctors continued to use the drug before and after surgery for its calming effect.
It’s no longer in use today. In the United States, the Drug Enforcement Administration (DEA) classifies desomorphine as a Schedule I substance. This means it has a high potential for misuse without any accepted medical use.
Codeine tablets are available without a prescription in Russia. Inexpensive and readily available substances are combined with the codeine to make the homemade or street version of the drug, krokodil.
People use it as a cheaper substitute for heroin.
The most recognized side effect of krokodil is scaly green and black skin that develops shortly after injecting the drug.
Based on reports, people don’t need to use the drug for long to experience permanent and serious tissue damage that extends as deep as the bone.
Let’s take a closer look at the side effects responsible for the drug’s street name as well as its other side effects.
The damage is believed to be at least partly caused by the toxic effect of the additives used to make the drug, most of which are erosive to skin.
The drug is also not purified before injection. This may explain why the skin irritation happens almost immediately after injection.
Muscle and cartilage damage
The ulcerated skin often progresses to severe muscle and cartilage damage. The skin continues to ulcerate, eventually sloughing off and exposing the bone underneath.
Blood vessel damage
Krokodil can damage the blood vessels that prevent the body’s tissues from getting the blood it needs. Blood vessel damage associated with the drug can cause gangrene. It can also lead to thrombophlebitis, which is inflammation of a vein caused by a blood clot.
Bone infections (osteomyelitis) and bone death (osteonecrosis) in parts of the body separate from the injection site have also been reported.
Bacteria are able to enter the bone through the deep tissue wounds, causing infection. Bone death occurs when blood flow to the bone slows or is stopped.
Amputation is sometimes needed to treat this type of damage.
Use of krokodil has been associated with a number of other serious side effects and complications, including:
- sepsis, also referred to as blood poisoning
- kidney failure
- liver damage
- brain damage
- drug overdose
Krokodil (desomorphine) is a dangerous and potentially fatal drug that causes a number of side effects.
Its toxic effects are experienced immediately after injecting it and progress very quickly.
