“Zaza” has two distinct meanings depending on who’s using the term. In cannabis culture and hip-hop, it’s slang for high-grade, “exotic” marijuana. But in recent years, “Zaza” more commonly refers to a brand of gas station supplements containing tianeptine, a substance that acts on opioid receptors in the brain and has caused seizures, hospitalizations, and deaths across the United States.
Zaza as Cannabis Slang
The term originated in hip-hop circles as a way to describe premium, top-shelf weed, sometimes called “exotic” or “pressure.” It showed up in rap lyrics and online communities before crossing into mainstream slang. When someone calls cannabis “zaza,” they’re saying it’s high quality, potent, and likely from a designer or sought-after strain. This usage is still common, but it’s increasingly overshadowed by the other meaning.
Zaza as a Gas Station Supplement
The more concerning use of the name refers to products like Zaza Red and Zaza Silver, sold as dietary supplements in gas stations, convenience stores, and smoke shops. These products contain tianeptine, a chemical classified as an atypical antidepressant that’s prescribed in some European, Asian, and Latin American countries but is not approved for any medical use in the United States.
Tianeptine is often marketed with claims that it improves brain function, reduces anxiety, or treats pain. The FDA has explicitly stated that tianeptine does not qualify as a dietary ingredient and is an unsafe food additive. In January 2024, the agency sent letters to convenience store and gas station organizations urging them to stop selling tianeptine products entirely. As of May 2025, the FDA’s position remains firm: no tianeptine product is approved or recognized as safe.
Why Tianeptine Acts Like an Opioid
What makes tianeptine especially dangerous is that it interacts with the same receptors in the brain that opioids like morphine and fentanyl target. It binds to mu-opioid and delta-opioid receptors, producing euphoria, pain relief, and sedation at higher doses. People who take Zaza products for the first time may not realize they’re consuming something that behaves like an opioid, because it’s sold on a shelf next to energy drinks and vitamins.
This opioid activity is what drives both the appeal and the danger. Users report taking it for a mood boost or to manage pain, but the body adapts quickly. Some users in online communities have described taking tianeptine alongside other gas station substances like kratom and phenibut, a combination that compounds the risks significantly.
How Quickly Dependence Develops
Tianeptine dependence can develop with startling speed. In one documented case, a patient became dependent after just two weeks of use, taking 10 to 15 pills daily and needing to redose every four to six hours to avoid withdrawal symptoms. That timeline is fast enough that someone who starts using Zaza casually can find themselves physically dependent before they fully understand what they’re taking.
Withdrawal looks a lot like opioid withdrawal. Reported symptoms include agitation (in about a third of cases), nausea (also about a third), vomiting, rapid heart rate, high blood pressure, diarrhea, tremors, and excessive sweating. Some patients have reported more severe effects: chest pain, shortness of breath, blurry vision, fevers, chills, seizures, and urinary retention. Tremors and excessive sweating appear to be somewhat distinctive to tianeptine withdrawal compared to other opioids.
Overdose and Poisoning Cases Are Surging
The scale of the problem has grown dramatically. Poison control centers across the country received just 17 single-substance tianeptine exposure reports in 2015. By 2023, that number had climbed to 250, a 1,400% increase. Of those cases, 40% required hospital admission, and nearly one in four was serious enough to need a critical care unit.
Alabama became a particular hotspot. The state’s tianeptine exposure rate surged over 1,400% between 2018 and 2021, earning Zaza the nickname “gas station dope” before Alabama moved to ban the substance. The FDA has continued receiving severe adverse event reports tied to tianeptine products, including seizures, loss of consciousness, and death. In February 2024, a major distributor of the brand Neptune’s Fix, another popular tianeptine product, issued a recall.
Where Tianeptine Is Banned
There is no federal ban on tianeptine in the United States, but a growing number of states have classified it as a controlled substance. Alabama was among the first, initially placing it in Schedule II before upgrading it to Schedule I, the most restrictive category. As of early 2024, states that have scheduled tianeptine include Florida, Georgia, Indiana, Kentucky, Michigan, Minnesota, Ohio, Virginia, Tennessee, Oklahoma, Arkansas, and Mississippi, among others. The specific scheduling level varies by state, ranging from Schedule I (no accepted medical use) to Schedule III.
In states where tianeptine remains unscheduled, the products can still be found on store shelves. The patchwork of state laws means availability depends largely on where you live, and purchasing online remains possible in many areas despite FDA warnings.
What Zaza Products Actually Contain
The exact formulations of Zaza products have raised additional concerns because the labeling doesn’t always reflect what’s inside. Toxicologists at the University of Alabama at Birmingham investigated these products and found that users commonly combine tianeptine with other unregulated substances, including phenibut (a sedative compound), racetams (marketed as cognitive enhancers), and kratom. Zaza Silver, for instance, has been associated with ingredients beyond tianeptine alone, making the risk profile even harder to predict.
This unpredictability is part of what makes these products so hazardous. A person buying a bottle at a gas station has no reliable way to know the actual dose of tianeptine per pill, whether the formulation has changed between batches, or what other active compounds might be present. Unlike regulated pharmaceuticals, these products undergo no standardized testing for potency or purity before reaching consumers.
