New substances continue to emerge in the illicit drug supply, creating challenges for public health officials, healthcare professionals, and communities. One group receiving increased attention is orphines, a class of synthetic opioids that has been identified in drug samples and toxicology cases in the United States and other countries.
Understanding what orphines are, why they are concerning, and what people should know about opioid overdose is an important part of substance use prevention.
What Are Orphines?
Orphines, also known as benzimidazol-2-one opioids, are a group of synthetic opioids that includes multiple individual substances, such as cychlorphine. Some substances in this group may be highly potent, increasing the risk of a life-threatening overdose because opioids can slow or stop breathing. Unlike morphine, which is a medication used to treat severe pain, orphines are associated with emerging threats in the illicit drug supply.
Some substances in this group have been found in toxicology investigations involving suspected fatal overdoses. Their presence alongside other substances can make the effects even more unpredictable.
Why Are Orphines a Concern?
One challenge with emerging synthetic opioids is that their risks may not be fully understood when they first appear. The composition of the illicit drug supply can change, and people may not know what substances are present in a drug they encounter.
Orphines also present challenges for drug detection. According to the United Nations Office on Drugs and Crime, orphines are not detected by fentanyl or nitazene test strips. This means a negative result from these particular tests cannot rule out the presence of an orphine.
These limitations highlight why education and awareness are important. Familiarity with a drug’s appearance or a test result alone cannot establish what a substance contains or whether it is safe.
Recognizing an Opioid Overdose
Because orphines are synthetic opioids, it is important to recognize the signs of an opioid overdose and know how to respond. If you suspect an opioid overdose, call 911 immediately and administer naloxone (Narcan) if it is available. Follow the emergency dispatcher’s instructions and stay with the person until help arrives. Naloxone can reverse an opioid overdose, although additional doses or further medical treatment may be needed.
Why Awareness Matters
Orphines are one example of how the illicit drug supply continues to evolve. While reports of these substances do not tell us exactly how common they are in every community, they demonstrate the importance of keeping prevention information current.
Learning about emerging substances, understanding the limitations of drug detection, and knowing how to respond to an overdose can help people make informed decisions and respond when someone needs help.
Staying informed is an important part of prevention. The more we understand emerging substance-related risks, the better prepared we are to support safer, healthier communities.
