What do gas stations, convenience stores, smoke shops, and online retailers have in common? Among many things, they’ve become places to acquire new, dangerous, and addictive substances. Often referred to as “gas station drugs,” products like kratom, delta-8 THC, and phenibut take advantage of legal loopholes that enable them to sit on the shelves of neighborhood retailers. One substance in particular, tianeptine or “gas station heroin,” is under the microscope for its emerging threats to public health.
Understanding Tianeptine (Gas Station Heroin)
What is gas station heroin? For starters, it’s a drug that has the US government’s attention. In a 2025 letter to healthcare professionals, the U.S. Food and Drug Administration (FDA) warned that tianeptine had been linked to a growing number of harmful incidents nationwide, especially among younger users. In some cases, these adverse events resulted in severe injury or even death.
Tianeptine is also prescribed in certain countries throughout Europe, Asia, and South America to treat conditions like depression, anxiety, and irritable bowel syndrome (IBS). First introduced in France in 1971 as an antidepressant, the medication eventually became available in over 60 countries, according to ACS Chemical Neuroscience. Over time, researchers found tianeptine affects the brain like opioids, interacting with opioid receptors in a manner comparable to drugs like fentanyl or oxycodone. Because of this, regular use of gas station heroin can lead to tianeptine withdrawal and abuse.
Here in the US, however, tianeptine is not approved as a medication. Instead, it is often marketed as a recreational substance that claims to:
- Enhance mood
- Improve focus
- Increase cognitive abilities
- Boost energy
- Ease pain
- Strengthen sexual performance
- Reduce appetite
These products are commonly sold in gas stations, truck stops, mini marts, vape shops, and online. Gas station heroin is often packaged in brightly colored, shot-sized bottles under brand names such as ZaZa, Neptune’s Fix, Tianaa, Pegasus, and TD Red, shares the FDA.
Despite how it’s labeled, the FDA does not recognize gas station heroin as safe for medical use, as a dietary ingredient, or as a food additive. Still, manufacturers frequently exploit regulatory gray areas by branding these products as dietary supplements, research chemicals, or cognitive enhancers. Phrases like “not for human consumption” may even be on bottles, even though the products are being sold to humans for consumption, for example.
Tianeptine Withdrawal, Addiction, and Other Health Risks
Since tianeptine products are widely available in familiar retail environments, people will assume they are safe. Unfortunately, such an assumption is incorrect. With no government regulation on the manufacturing of gas station heroin, its potency can vary significantly. Certain products may even contain additional harmful substances, including synthetic cannabinoids, according to NPR News. Reports also suggest that some users consume doses far exceeding those recommended in countries where tianeptine is prescribed. In extreme cases, the doses are hundreds of times higher.
Harmful side effects have been linked to tianeptine use, too. The FDA shares that U.S. poison control centers have seen increased reports of adverse reactions to gas station heroin over the past two decades. Effects of tianeptine exposure can include:
- Agitation
- Drowsiness
- Confusion
- Sweating
- Rapid heartbeat
- Increased blood pressure
- Nausea and vomiting
- Slow or stopped breathing
- Coma
- Death

Like opioids, repeated or high-dose use of tianeptine can lead to tolerance, dependence, and addiction. Some users report experiencing brief feelings of euphoria at larger doses, which can increase the risk of overdose. When people attempt to stop after regular use, they may face tianeptine withdrawal symptoms that make it harder to quit, such as:
- Anxiety
- Agitation
- Gastrointestinal distress
- Myoclonic jerking

Addiction can develop as gas station heroin alters your brain’s reward system. Tianeptine use triggers the release of dopamine, reinforcing your desire to repeat the experience. Over time, your brain adapts by reducing its sensitivity to dopamine, meaning higher doses are required to achieve the same effect. This cycle can eventually result in chemical dependence and tianeptine addiction.
