“Gas Station Heroin” Tianeptine Sparks New State Bans as Doctors Warn of Deadly Overdoses
Tianeptine — nicknamed “gas station heroin” — is an unapproved substance sold as supplements and online that can produce opioid-like effects at high doses, prompting state bans and urgent warnings from clinicians amid rising overdoses and deaths.
Key takeaways
- Tianeptine is a tricyclic antidepressant that can act like an opioid at high doses; it is not approved for use in the U.S. (FDA, Mayo Clinic).
- Products labeled as supplements or nootropics are sold at gas stations, convenience stores, vape shops and online under street names such as Tianaa, ZaZa, Neptune’s Fix, Pegasus and TD Red (VCU Health).
- At high doses tianeptine stimulates mu-opioid receptors and can cause severe respiratory depression, sedation and death (NCBI, FDA).
- At least 14 states have scheduled tianeptine as a controlled substance and Connecticut recently banned its sale and use to curb harm (VCU Health).
What tianeptine is and how it works
Tianeptine is an antidepressant legally prescribed in parts of Europe, Asia and South America but has never been approved by the U.S. Food and Drug Administration. For official guidance see the FDA fact sheet.
At low doses tianeptine affects serotonin pathways. At higher doses it can act on mu-opioid receptors producing euphoria, respiratory depression and cardiac arrest — the same receptor family targeted by heroin and prescription opioids (NCBI analysis; FDA).
“The euphoria can move from serotonin effects at low doses to dangerous mu-opioid receptor stimulation at higher doses — the same pathway that can lead to fatal respiratory failure,” said Dr. Robert Schwaner of Stony Brook Emergency Medicine.
How it’s marketed and where it’s sold
Manufacturers and distributors sell tianeptine products as dietary supplements or nootropics, claiming benefits for pain, anxiety, depression or mental focus. They are available in pills, powders, salts and liquids and marketed under brand and street names like Tianaa, ZaZa, Neptune’s Fix, Pegasus and TD Red (FDA; Mayo Clinic).
Retail outlets include gas stations, convenience stores and vape shops, and online sellers ship nationwide, increasing availability and complicating enforcement (VCU Health).
Health risks, poisonings and overdose patterns
Misuse has been associated with agitation, confusion, heavy sedation, slowed breathing, coma and death. Reported effects also include nausea, seizures, sweating, rapid heartbeat and dangerously low blood pressure (FDA).
Poison centers have documented a sharp rise in tianeptine-related calls since about 2016. Some hospital systems report many patients require intensive care; the Virginia Poison Center found ~one-third of cases needed ICU-level monitoring in 2024.
New Jersey health officials documented clusters of severe illness and deaths tied to products containing tianeptine and other toxic ingredients, including synthetic cannabinoids — see the NJ Health alert.
Danger increases when tianeptine is combined with alcohol, benzodiazepines or other opioids. Standard drug screens often do not detect tianeptine, slowing diagnosis and complicating emergency treatment (FDA).
State and federal responses
Faced with rising poisonings, at least 14 states have listed tianeptine as a Schedule I controlled substance citing its lack of U.S. medical approval and abuse potential (VCU Health).
Connecticut recently banned its sale and use and added other substances such as kratom and certain synthetic opioids to its controlled schedule. The FDA has issued warnings that tianeptine is not an approved dietary supplement and urged caution.
Clinicians and toxicologists are calling for stronger federal action to close gaps left by state-by-state bans and to reduce online sales and shipping across jurisdictions (see FDA guidance).
Prevention and treatment resources
Anyone concerned about tianeptine exposure should call poison control at 1-800-222-1222. People seeking help for substance use can contact SAMHSA’s National Helpline for free, confidential support and referrals in English and Spanish via the SAMHSA helpline page.
Clinicians treating suspected toxicity should consider opioid-like effects, monitor respiration, and consult regional poison centers. Because routine screens may miss tianeptine, specialized testing or empiric treatment while contacting experts is often necessary (FDA).
Implications for Sonoma, California
Public safety and hospitals: Sonoma County emergency departments and urgent care centers should prepare for potential tianeptine cases — severe sedation, respiratory depression or withdrawal may require ICU-level care. Coordinate with county public health and regional poison centers for testing and treatment guidance (VCU Health; NJ Health alert).
Retail oversight and enforcement: Local stores and vape shops should review suppliers and inventory. City and county code enforcement, alongside state regulators, can work to remove unauthorized tianeptine products from shelves and online marketplaces that ship into the region (FDA).
Youth and community outreach: Candy-like flavors and misleading marketing increase risks for teenagers. Sonoma school districts, youth organizations and parent groups should be briefed on signs of use and where to get help; local campaigns can mirror FDA messaging (FDA).
Treatment access: Behavioral health providers and recovery programs should ensure clear referral pathways and link residents to state and federal resources such as the SAMHSA helpline.
Law enforcement and policy: County leaders may track sales and distribution and review local ordinances to limit access and protect vulnerable populations in light of multiple states scheduling tianeptine (VCU Health).
Bottom line
Medical experts and federal agencies warn the risk will continue while tianeptine is sold as a supplement and shipped online. Local health officials in Sonoma and across California can reduce harm by educating the public, tightening retail oversight, and ensuring clinicians and first responders recognize and treat tianeptine-related harm (FDA; VCU Health; NJ Health).
