Designer Drugs: The Next Wave of Overdose Deaths

For years, physicians, public health workers, and peer recovery specialists have given practical harm reduction advice to people who continue to use street drugs: never use alone, take a small test dose, avoid mixing drugs, and always keep naloxone nearby.

That advice still matters. Naloxone can reverse opioid overdoses, including overdoses involving fentanyl and cychlorphine, though powerful synthetic opioids may require repeat dosing. Having another person present can also make the difference between life and death if breathing slows or stops.

But designer drugs like cychlorphine, xylazine, and medetomidine complicate this advice in dangerous ways.

A test dose may not reveal the full risk because street drugs are often unevenly mixed. One small amount may contain little or none of the adulterant, while the next dose may contain a deadly concentration. This is especially concerning with cychlorphine, which is reportedly far more potent than fentanyl and cannot yet be reliably detected by common test strips.

Naloxone also has limits. It works on opioids, which means it may help reverse an overdose involving cychlorphine. But xylazine and medetomidine are not opioids, and naloxone does not reverse their sedating effects. If a person has used fentanyl mixed with xylazine or medetomidine, naloxone may still help with the opioid portion of the overdose, but the person may remain dangerously sedated and still require emergency medical care. Even after naloxone is given, death remains a real possibility.

If an overdose is suspected, call 911 immediately. Administer naloxone as soon as possible. Naloxone restores breathing during an opioid overdose, and if the person begins breathing normally again, additional naloxone is not needed at that time—but the person should continue to be carefully monitored until EMS arrives. Rescue breaths are also critical. Supporting breathing while naloxone takes effect provides immediate oxygen and can save a life. If the person does not respond, or if breathing slows again, another dose of naloxone may be needed.

Mixing substances creates even greater risk. Opioids, alcohol, benzodiazepines, gabapentin, muscle relaxers, and veterinary sedatives can all depress the central nervous system. When combined, they can slow breathing, lower awareness, and increase the risk of fatal overdose.

This is why the safest advice remains clear: do not use street drugs. For those already struggling with substance use, the next safest step is to seek treatment, carry naloxone, avoid using alone, and call 911 immediately if someone becomes unresponsive, stops breathing normally, or develops blue or purple lips or fingernails.

These new drugs show why harm reduction alone is not enough. Public awareness, rapid emergency response, expanded naloxone access, drug-checking technology, and evidence-based treatment must all be part of the answer.

Addressing these evolving drug threats requires more than one approach. Harm reduction strategies—such as ensuring naloxone access—remain life-saving. Public awareness and education are vital to reducing stigma and encouraging treatment. Equally important is expanding access to effective, evidence-based care. Together, these efforts can save lives and empower individuals and communities to face these challenges with hope and support.
