Zaza is a slang term for tianeptine , a drug originally developed as an antidepressant but known for its opioid-like effects. It is often referred to as "gas station heroin" because it is frequently sold in gas stations, convenience stores, and online as a legal alternative to traditional narcotics despite not being approved for medical use in the United States. Tianeptine acts on the brain's opioid receptors, producing effects similar to heroin or prescription painkillers, which has led to its misuse for getting high. It is typically available in capsule or powder form and is sometimes marketed as a dietary supplement, making it easily accessible. However, Zaza is unregulated, and its contents can be unpredictable and dangerous. The use of Zaza carries significant risks including addiction, severe withdrawal symptoms, heart problems, respiratory failure, and mental health issues such as anxiety, paranoia, and depression. Despite its antidepressant origins, misuse of tianeptine can lead to serious health consequences and even death. In summary, Zaza is a potent and dangerous synthetic drug with opioid-like effects that is commonly misused and poses serious public health concerns. Its accessibility and the false perception of safety due to its legal status make it particularly hazardous.
