New Psychoactive Stubstances

What are new psychoactive substances (NPS) and why do they matter?

New psychoactive substances are drugs outside international conventions but still capable of creating major health risks. They emerge quickly, are often sold as legal highs, and can lead to overdoses, psychosis, and organ failure. Understanding their categories helps clinicians, patients, and families recognize dangers and adapt recovery strategies effectively.

1. Synthetic cannabinoids

These are chemicals sprayed on plant matter and marketed as safe cannabis alternatives. They can cause seizures, psychosis, and sudden death, with unpredictable potency making them far more dangerous than marijuana.

2. Synthetic opioids

Often stronger than heroin or morphine, substances like fentanyl analogs drive waves of overdoses worldwide. Minute dosing differences can cause respiratory failure, making them especially lethal and difficult to manage in emergencies.

3. Synthetic cathinones

Stimulants sold as bath salts can trigger extreme agitation, paranoia, and hyperthermia. Examples such as mephedrone and alpha-PVP are notorious for causing violent behavior, organ damage, and long-lasting psychological distress.

4. Benzodiazepine analogs

These sedatives, including etizolam, lead to blackouts and fatal overdoses, especially when mixed with alcohol or opioids. Unlike opioids, their effects are not reversible with naloxone, making interventions more complex and riskier.

5. Plant-derived and mixed adulterants

Khat, xylazine-laced opioids, and branded blends like grey death or purple heroin add unpredictable risks. Adulterants complicate testing and treatment, with toxic mixtures often contributing to surges in overdose deaths and emergency hospitalizations.

How are NPS classified and what substances are most common today?

New psychoactive substances appear in varied categories, each with unique dangers, making recognition critical for clinical care and harm reduction. Rapid shifts in the drug supply introduce highly potent analogs and unpredictable mixtures. Below are the major groups most frequently seen today in seizures, toxicology screens, and emergency responses worldwide.

Synthetic opioids

Nitazenes like isotonitazene and butonitazene, as well as brorphine, can equal or surpass fentanyl in strength. Their extreme potency makes overdoses common, and they are often disguised in counterfeit pills or mixed into powders without user knowledge.

Synthetic cannabinoids

These man-made chemicals bind strongly to CB1 receptors, causing agitation, psychosis, seizures, and heart problems. Marketed as herbal incense or blends, they pose unpredictable risks due to inconsistent dosing and contamination with other toxic compounds.

Synthetic cathinones

Known as bath salts, these stimulants include alpha-PVP and mephedrone. They can trigger severe paranoia, hyperthermia, and violent agitation. Their unpredictable effects have led to high rates of emergency visits and long-lasting mental health consequences.

Benzodiazepine analogs

Compounds like etizolam act as powerful sedatives that can cause blackouts and respiratory depression. Risks rise sharply when combined with opioids or alcohol, and unlike opioid overdoses, their effects cannot be reversed with naloxone.

Plant-derived and mixed adulterants

Khat, xylazine-laced opioids, and branded street mixes such as purple heroin or grey death complicate detection and treatment. These adulterated substances carry unpredictable toxicity, fueling surges in overdoses and overwhelming healthcare systems.

What should clinicians know about nitazenes like butonitazene and isotonitazene?

Nitazenes are highly potent synthetic opioids first synthesized in the 1950s. Isotonitazene has been detected in fatal overdoses and is often mixed with stimulants such as cocaine, escalating risk. Butonitazene is widely available online and poses similar dangers of respiratory depression, altered heart rate, loss of consciousness, and death.

Toxicology can miss nitazenes on standard screens, delaying diagnosis. Clinicians should treat suspected opioid toxicity with naloxone, anticipate the need for repeated dosing due to high potency, monitor for re-sedation, and consider polysubstance exposure that may require additional supportive care and airway management.

Is etizolam safer than prescription benzodiazepines?

No. Etizolam is a benzodiazepine analog used medically in some countries but not approved in the United States. Recreational use is linked to hallucinations, agitation, profound sedation, and overdose, especially when combined with opioids or alcohol. Naloxone will not reverse etizolam effects.

Illicit tablets and powders vary widely in dose and may contain additional depressants. Management focuses on supportive care, airway protection, and cautious use of flumazenil only when clearly indicated and safe, given seizure risk in polysubstance exposure or chronic benzodiazepine users.

How dangerous are grey death, smurf dope, and purple heroin?

These branded mixtures can contain heroin or methamphetamine combined with fentanyl, carfentanil, brorphine, or other potent adulterants. Visual cues like concrete-like grey or vibrant blue color are unreliable indicators of content or potency and should not guide safety assumptions.

Presentation often includes cyanosis, snoring respirations, unresponsiveness, and respiratory failure. Treat as suspected opioid overdose with naloxone while preparing for multiple doses and advanced airway support. Expect wide regional variability and rapid shifts in composition.

What are the risks of khat, lean, and tianeptine/Tianaa?

Khat is a plant stimulant with effects similar to amphetamines; high doses can induce psychosis and violence. Lean blends codeine cough syrup with soda and candy, appealing to youth but still an addictive opioid mixture with overdose risk. Tianeptine, sold as supplements or research chemicals, has caused severe dependence and withdrawal.

• Khat: Stimulant effects include euphoria, tachycardia, and insomnia; chronic use may lead to psychological dependence and psychosis-like symptoms.
• Lean (codeine mixtures): Respiratory depression risk increases with alcohol or benzodiazepines; dependence and withdrawal are common.
• Tianeptine/Tianaa: Associated with hospitalization, multi-system effects, and rapid tolerance; some overdoses may respond to naloxone due to opioid receptor activity.

Why is xylazine in the drug supply and how should overdoses be managed?

Xylazine is a veterinary sedative frequently mixed with opioids to prolong or deepen sedation, creating tranq dope. It does not respond to naloxone, but naloxone should still be administered for suspected co-occurring opioids, followed by supportive measures for hypotension, bradycardia, and profound CNS depression.

Complications include severe skin ulcers, necrosis at injection sites, and prolonged sedation that outlasts opioid effects. Management emphasizes wound care, fluids, vasopressor support when indicated, and harm reduction counseling, including safer use supplies and linkage to treatment.

How can communities detect and respond to rapidly emerging NPS?

Communities benefit from coordinated surveillance, flexible clinical protocols, and swift public alerts. Early warning systems, hospital poison center data, wastewater testing, and forensic labs can identify trends and trigger response actions to reduce deaths and harms.

1. Build local early warning capacity

Establish data-sharing among EMS, emergency departments, medical examiners, and public health to detect clusters, track adulterants, and disseminate timely alerts. Integrate qualitative reports from outreach workers and drug checking services to capture street-level shifts quickly and guide targeted interventions.

2. Expand drug checking and test availability

Support community drug checking with validated methods and distribute test strips for fentanyl and xylazine where legal. Provide clear instructions about limitations, encourage small test doses, and use findings to inform alerts, clinical training, and outreach messaging tailored to local supply dynamics.

3. Standardize clinical protocols

Create protocols for high-potency opioid overdoses, prolonged sedation, and mixed intoxications. Include guidance on repeated naloxone dosing, airway management, xylazine complications, and benzodiazepine analog exposures. Update order sets and training as new compounds emerge and evidence evolves.

4. Scale harm reduction and treatment linkage

Increase access to naloxone, safer use supplies, and same-day medications for opioid use disorder. Co-locate wound care and behavioral health supports with outreach. Use nonjudgmental messaging to engage people who use drugs and reduce barriers to ongoing care and monitoring.

5. Communicate clearly to the public

Issue concise alerts describing observed substances, expected effects, and actionable steps. Avoid stigmatizing language, include symptoms that should prompt a 911 call, and offer links to local services and credible national resources to build trust and encourage help-seeking behavior.

What immediate steps reduce harm if NPS exposure is suspected?

If someone shows overdose symptoms, call emergency services, administer naloxone for suspected opioids, and monitor breathing. Place the person in the recovery position, avoid mixing substances, and seek medical evaluation even if symptoms improve due to risk of re-sedation or delayed toxicity with long-acting or unknown compounds.

Keep multiple naloxone doses available, use fentanyl and xylazine test strips where permitted, and start with small doses if using. Save product samples for potential testing, which may inform clinical care and public alerts. Engage with local harm reduction services for supplies, education, and treatment referral.

Where can professionals find credible guidance and surveillance on NPS?

Clinicians and public health teams should align local protocols with updated advisories and evidence summaries while collaborating across healthcare, public health, law enforcement, and community organizations for rapid knowledge translation. For those also focused on whole-person healing, incorporating therapeutic sound bath practices may support stress regulation and engagement in care alongside standard treatment.

Stay current through poison control center updates, UNODC Early Warning Advisory reporting, and regional public health alerts that track NPS trends, toxicology, and clinical management. Shared situational awareness improves triage, reduces time to appropriate care, and helps communities respond to market shifts before harms escalate.
