Many parents have heard about fentanyl. But fewer know that new lab-made opioids are already taking its place in the illegal drug supply. One fast-growing group is called orphine analogues, or simply “orphines.”
These drugs are extremely strong, hard to detect, and linked to a rising number of fatal overdoses across the United States and Canada.
Orphines are a new group of powerful opioids appearing in the illegal drug supply. This article explains what they are, why they are dangerous, how to recognize an overdose, and what parents can do to protect their children.
Orphines are a group of strong opioids that were first created in a drug research lab in Belgium in the 1960s. Scientists were looking for powerful pain-relieving and anesthesia drugs for medical use.
One of the drugs they made was called bezitramide. It was tested on people during the 1970s and 1980s and was used in parts of Europe to treat severe, long-lasting pain. Over time, however, it became clear that this drug was very dangerous. After several overdoses in the Netherlands, it was taken off the market in 2004.[1]
Today, illegal versions of similar drugs — now called orphines — have started showing up in the street drug supply. Some of the more common ones include cychlorphine, brorphine, spirochlorphine, and chlorphine.
Not all orphines affect the body in the same way, but they can be extremely powerful. Some are chemically similar to fentanyl and nitazenes, two of the most dangerous opioids today. Others, like cychlorphine, may be 50 to 200 times stronger than heroin.
Several orphines, including brorphine and cychlorphine, have already been linked to fatal overdoses around the world.
Orphines first appeared in the illegal drug supply around 2020 with brorphine. Since then, at least six types have been found, and new ones continue to appear.
One of the newest and most concerning orphines is N-propionitrile chlorphine.
This drug is not approved for medical use and has no known safe dose.
In July 2025, the Chinese government placed nitazene analogues (another group of powerful lab-made opioids) under tighter control. After that change, nitazenes showed up less often while orphines increased in the drug supply. This constant change makes the drug supply more dangerous and unpredictable.
The data, coming from cases in nine states in the U.S. and 3 Canadian provinces, is alarming.[2]
This drug has been found alone as well as mixed with other opioids like fentanyl and counterfeit pain pills. It has also been mixed with stimulants like cocaine and methamphetamine. Mixing drugs including alcohol greatly increases the risk of overdose.
In the event of an overdose, call 911 immediately.
Use naloxone right away if available.
You don’t need to know all the chemistry. What matters most is how you start the conversation.
Try opening with curiosity instead of fear:
Focus on safety, not punishment:
Be honest:
The rise of orphines like N-propionitrile chlorphine shows how quickly the drug landscape can change. These substances are stronger, newer, and more unpredictable than ever before.
But parents still matter. Staying informed, connected, and focused on safety can save lives.
Orphines are a group of powerful lab-made opioids. They include cychlorphine, brorphine, spirochlorphine, and chlorphine. They are not approved for medical use in the United States and may be found in powders, fake pills, or mixtures containing other drugs.
Early laboratory findings suggest that cychlorphine may be about 10 times stronger than fentanyl. Even a very small amount may slow or stop breathing. Because illegal drugs are not made under safe conditions, there is no way to know how strong a pill or powder may be.
Yes. Orphines have been found in counterfeit pills and mixed with fentanyl, cocaine, methamphetamine, and other drugs. A person may believe they are taking a pain pill, stimulant, or another familiar drug without knowing that it contains a powerful opioid.
No. Fentanyl test strips are made to detect fentanyl and some related substances. They do not reliably detect orphines. A negative test does not mean a pill or powder is safe.
Naloxone can reverse an overdose caused by opioids, including orphines. More than one dose may be needed. Give the first dose, call 911, and give another dose after two to three minutes if the person does not begin breathing normally. Stay with the person until help arrives.
