“Gas Station Heroin”: The Dangers of ZaZa and Other Tianeptine Products 

At Windmill Wellness Ranch, we know it can seem like new addictive substances are hitting the market all the time. People are often drawn to anything new that promises a high, but one of the most disturbing trends in recent years is how many of these drugs are legal and sold in gas stations and vape shops with flashy, misleading packaging. 

We have written extensively about 7OH, MGM15, and other kratom-derived products, but today we are turning the spotlight to a drug that began as a medication and is now increasingly being misused in ways its developers likely never intended. 

An Old Antidepressant Becomes a New Drug of Abuse 

Meet tianeptine, often marketed under names like ZaZa, Tianaa, and Pegasus. Tianeptine (pronounced “tie-uh-NEP-teen”) was introduced as an antidepressant in 1989 and received significant medical attention, but it was never approved for use in the United States. Other countries did allow it for a time, although some have since banned or restricted it because of rising misuse and abuse.1 

Although it was not approved in the U.S., it was not initially banned either. In that legal gray area, people discovered that taking more than a standard therapeutic dose could produce opioid-like effects. In countries where tianeptine is still prescribed as an antidepressant, doses typically range from 25 mg to 50 mg per day, but some people misusing products like ZaZa may take many times that amount.1 

Today, it is often sold as a “nootropic” supplement, a category of products marketed as helping with calm, focus, mental clarity, or energy, despite the fact that these claims are often unproven and the substance itself has not been approved by the FDA for medical use in the United States. 

In fact, the FDA has issued multiple warnings about tianeptine and has warned consumers not to purchase or use these products because of serious risks, including overdose and death.2 

What Is ZaZa? 

ZaZa is a brand name associated with products that contain tianeptine. It is potent enough that many people refer to it as “gas station heroin.” These products are often marketed as offering: 

• Relaxation  

• Focus  

• Anxiety relief  

• Mood enhancement  

• Energy  

• Pain relief  

Like other opioid-like substances, these effects may seem appealing at first, but tolerance can build quickly. As that happens, the user may need more and more of the drug to feel the same effects. Before long, what seemed like an energy booster or mood aid can turn into an ZaZa addiction. 

Common signs may include: 

1. Cravings  
2. Mood swings  
3. Sedation or unusual fatigue  
4. Nausea or vomiting  
5. Financial problems related to purchasing products  
6. Secretive behavior  
7. Anxiety or agitation between doses  
8. Taking increasingly larger amounts  
9. Difficulty functioning without the drug  

This often leads to taking even more ZaZa. Before long, the person is not just trying to recreate the initial high, but trying to avoid withdrawal. People who have become dependent on tianeptine often describe tianeptine withdrawal as similar to heroin or fentanyl withdrawal, with symptoms such as sweating, tremors, insomnia, depression, anxiety, chills, rapid heart rate, restlessness, nausea, vomiting, and intense cravings. 

In other words, what starts as a few ZaZa pills can quickly turn into tianeptine dependence and then full tianeptine addiction. 

What Makes ZaZa and Similar Products So Dangerous 

If addiction and withdrawal were not serious enough, ZaZa also carries a significant risk of overdose. Part of that risk comes from the way tolerance drives people to take more and more, but another major issue is that these products are unregulated substances marketed as though they are safe supplements. 

Many users may be shocked to learn that, even when the packaging offers little or no warning, the contents may vary in strength, purity, or ingredients. Some products may contain undisclosed substances in addition to tianeptine. For example, some tianeptine products have been found to contain synthetic cannabinoids.2 

In an overdose, a person may experience central nervous system depression, muscle pain, weakness, vomiting, confusion, and respiratory depression.4 As with other opioid-like drugs, slowed or stopped breathing is one of the most life-threatening dangers. 

This risk is serious enough that the medical literature includes a documented fatality involving tianeptine.5 If you or someone you know is experiencing suicidal thoughts, seek help immediately by calling or texting 988 in the U.S. 

To add to this, first responders and medical professionals dealing with an overdose have almost no way to tell if someone has been using ZaZa. There is no standard on-the-spot test for tianeptine. A lab can tell if it has been used, but such a test is expensive and takes days, while professionals have to make life-saving decisions in seconds or minutes at most. It doesn’t help that many users are taking ZaZa with other drugs and may not even think to mention it when asked what they have been using. 

ZaZa overdose may respond to naloxone [Narcan], so if someone seems to be overdosing on opioids, there is a chance that naloxone treatment can save them from a ZaZa fatality. 

As with 7OH, ZaZa and similar products are particularly dangerous to people who are trying to recover from other drugs. They may take their first dose thinking they aren’t doing anything that could be bad for their recovery, but soon the symptoms start to feel frighteningly familiar. Before long, they are experiencing what feel like opioid withdrawal symptoms, cravings, and fast-growing dependence. 

All of this means that if someone is struggling with Zaza addiction, professional treatment is the safest option.
