We’re your essential guide to navigating the severe health risks and promoting safety and awareness.
A vibrant pink powder is making its way through the world’s nightlife scenes, from the sun-drenched parties of Ibiza to the bustling clubs of Miami and New York. Known by alluring names like “pink cocaine,” “tusi,” or “cocaina rosada,” it is promoted as a glamorous, high-end party favor—a symbol of a new wave of recreational drug use. Its growing presence has been noted across Latin America, and its deceptive allure has reached communities in Costa Rica.
But behind the trendy color and catchy nicknames lies a dangerous and fundamental deception. This substance is almost never cocaine. Nor is it the specific psychedelic drug, 2C-B, that its name phonetically mimics. Tusi is a dangerously unpredictable and unregulated chemical cocktail, a game of pharmacological roulette where the stakes can be lethal. Every dose is a mystery, a combination of substances that can range from stimulants and hallucinogens to deadly synthetic opioids like fentanyl.
This article will dismantle the myths surrounding tusi. It provides an evidence-based examination of the drug’s true origins, its dangerously variable composition, the reasons for its alarming popularity, and the profound risks it poses to physical and mental health. For communities in Costa Rica and around the globe, understanding this pink deception is a critical first step in recognizing its threat and navigating a path toward safety and awareness.
What is Tusi? The Misleading Identity of “Pink Cocaine”
The story of tusi is one of clever marketing and dangerous substitution. Its identity is built on a foundation of confusion, leveraging the reputation of one drug to sell a completely different, and far more unpredictable, chemical concoction.

The name “tusi” (and its variants like “tuci,” “tussi,” or “tucibi”) emerged as a phonetic Spanish pronunciation of “2C,” referring to the 2C family of synthetic psychedelic drugs, particularly 2C-B. This substance, first synthesized in the 1970s, gained popularity for combining stimulant and hallucinatory effects. However, the crucial point is this: the pink powder sold today as tusi rarely, if ever, contains any actual 2C-B or cocaine. Despite its misleading nickname, lab analyses confirm that modern tusi is primarily a mix of other, often more dangerous, substances.
The vibrant pink color and often sweet smell (like strawberries) come from food dye and added flavorings—purely for marketing appeal. This aesthetic, combined with savvy promotion as a “chic drug” or “designer drug,” creates a perception of exclusivity and trendiness, amplified by social media, further obscuring its true dangers.
Origins and Global Spread: A Rapidly Evolving Threat
Tusi first emerged in Colombia around 2018, gaining popularity in Medellín’s elite club scene. Initially, it did contain 2C-B, marketed as an upscale alternative. However, as 2C-B became scarce, traffickers substituted it with cheaper, more available drugs. This led to the highly variable “cocktail” formulation we see today, with ketamine often being the primary ingredient, frequently mixed with MDMA, caffeine, and methamphetamine.
From Colombia, tusi spread rapidly across Latin America, including Costa Rica, and then into European party circuits like Ibiza and Marbella. It has also made its way into major U.S. cities, such as Miami, New York, and Los Angeles. This global expansion is fueled by its accessible price point in some areas and its appeal as a “one-stop-shop” for a polydrug experience, eliminating the need for users to source and mix multiple substances themselves.
The Unpredictable Cocktail: What’s Really Inside Tusi?
The single greatest danger of tusi lies in its radical unpredictability. There is no standard formula. Every batch is different, and the only consistent feature is its pink color. This means users have no way of knowing what substances they are ingesting or in what concentration, making each use a life-threatening gamble.

Commonly detected ingredients in tusi samples include:
- Ketamine: The most prevalent ingredient, a dissociative anesthetic contributing to sedative and hallucinogenic effects.
- MDMA (Ecstasy/Molly): Frequently found, contributing stimulant and euphoric effects.
- Caffeine: Often added for its stimulant properties.
- Methamphetamine (Meth): A potent stimulant found in some batches.
- Opioids: Significantly concerning, various opioids, including fentanyl, oxycodone, and tramadol, have been detected. The presence of fentanyl, an extremely potent and often lethal substance, dramatically increases the overdose risk.
- Other substances: Lab tests have also detected synthetic cathinones (“bath salts”), xylazine (a veterinary tranquilizer), benzodiazepines, LSD, mescaline, and others.
The potent and varied combination of these substances can lead to severe, unpredictable effects, making tusi a veritable “chemical wildcard.”
The Severe Health Risks and Long-Term Consequences of Tusi Addiction
The euphoria and social enhancement sought from tusi come with a host of severe, unpredictable health risks. The varying chemical cocktail means effects can differ wildly from one use to the next, leading to a chaotic assault on the body and mind.
Immediate and Short-Term Risks
Users may experience a mix of stimulant, dissociative, and hallucinogenic effects. Desired effects can rapidly give way to dangerous side effects, including:
- Rapid heart rate and increased blood pressure.
- Nausea, vomiting, and dizziness.
- Confusion, disorientation, agitation, paranoia, and vivid hallucinations.
- Trouble breathing, low body temperature, and seizures.
- Blackouts and loss of consciousness.
- In severe cases, potentially sudden cardiac arrest and death (e.g., “excited delirium”).

Long-Term Consequences of Tusi Addiction
Repeated and prolonged use can lead to severe and irreversible health problems:
- Addiction and Dependence: Many common ingredients like methamphetamine and opioids are highly addictive, leading to tolerance and a compulsive cycle of use.
- Physical Health Damage: Chronic cardiovascular issues, including hypertension and increased risk of heart attack, alongside damage to the liver and kidneys.
- Mental Health Disorders: Profound psychological effects include severe anxiety, depression, paranoia, psychosis, mood swings, and cognitive impairments like memory loss and difficulty concentrating. Users may also experience flashbacks.
- High Overdose Risk: The unpredictable composition, especially the potential presence of fentanyl, makes overdose a grave concern. When fentanyl is present, even minute amounts can be fatal, and naloxone may not be fully effective against mixed-drug effects.
- Increased Vulnerability: The drug’s dissociative effects and impaired judgment can increase the risk of accidents, injury, and vulnerability to assaults.

The Danger of Unknowns: Why Tusi is So Hazardous
The core danger of Tusi lies in its unpredictable chemical composition and the complete lack of regulation. There is no standard formula, meaning no consistency and no safe dose. The contents vary wildly depending on the maker or dealer, often produced in small, homemade operations without quality control. This lack of standardization makes it a hazardous “mystery powder” where accurate dosage measurement is impossible.
The varying and unknown composition can lead to severe and unpredictable consequences:
- Unpredictable Effects: One use might bring euphoria, the next could lead to an ER visit. Effects range from stimulation and hallucinations to confusion, agitation, paranoia, and loss of consciousness.
- High Overdose Risk: The unknown potency and presence of substances like fentanyl dramatically increase overdose risk. Mixing with alcohol can also exacerbate effects, leading to serious illness or respiratory depression.
- Long-Term Health Issues and Addiction: Frequent use can result in addiction, physical and mental dependence, organ damage, cardiovascular problems, respiratory issues, severe mental health disorders, and cognitive impairment.
- Increased Vulnerability: Impaired judgment can lead to risky behaviors, accidents, and vulnerability to assault.
The appearance of Tusi, like cotton candy or strawberries, is purely a marketing tactic to make a dangerous substance seem benign, particularly to young partygoers.
Recognizing the Signs of Tusi Use and Overdose
Understanding the signs of Tusi use and, crucially, overdose, is vital. Since its effects are unpredictable, they can mimic other substances.

Signs of Tusi Use
- Behavioral: Unusual energy, hyperactivity, mood swings, aggression, risk-taking, social withdrawal, secretive behavior.
- Physical: Dilated pupils, increased heart rate, elevated blood pressure, excessive sweating, elevated body temperature.
- Cognitive/Psychological: Confusion, disorientation, paranoia, hallucinations, severe anxiety, memory loss, difficulty concentrating.
- Social/Personal: Presence of pink powder or residue on belongings.
Signs of Tusi Overdose
Tusi overdose is a significant risk due to its unpredictable and often toxic composition. Warning signs include:
- Severe agitation or confusion.
- Panic or extreme anxiety.
- Difficulty breathing or respiratory depression.
- Chest pain and cardiac arrest.
- Seizures.
- Loss of consciousness or fading in and out of consciousness.
- Dizziness and vomiting.
- Dangerously high body temperature or extreme sweating.
- Nausea or abdominal pain.
- Disorientation.
Immediate Life-Saving Actions:
Treat all suspected drug reactions as medical emergencies.
- Call emergency services immediately. Provide as much detail as possible.
- Stay with the person and try to keep them awake and breathing.
- Administer naloxone (Narcan) if available and opioid presence is suspected, but understand it may not be fully effective for non-opioid components.
- Avoid mixing Tusi with other substances, especially alcohol, as this significantly amplifies risks.
- If possible, bring a sample of the drug to the emergency room for testing.
Long-Term Recovery and Support for Tusi Addiction
Overcoming Tusi addiction requires a comprehensive, tailored approach due to its unpredictable composition. Recovery often begins with medical detoxification for safe withdrawal, followed by behavioral and psychological therapies such as CBT, DBT, MI, and trauma-informed therapy to address underlying issues and build coping skills.
Crucially, ongoing support systems are vital. Peer support groups (e.g., NA, SMART Recovery) offer community and shared experiences. Case management services assist with practical needs like housing and employment, while recovery coaches provide accountability. Aftercare planning, including continued therapy and relapse prevention, is crucial for maintaining sobriety.
At the Costa Rica Recovery Center, we understand the complexities of Tusi addiction and offer comprehensive programs designed to support individuals through medical detox, evidence-based therapies, and robust aftercare planning. We are here to help you or your loved one take that crucial first step towards a healthier, drug-free future.
FAQ: Understanding Tusi (“Pink Cocaine”)
What is Tusi, also known as “Pink Cocaine”?
Tusi is a street name that originated from the pronunciation of 2C-B, a synthetic hallucinogen. However, despite its misleading name, Tusi rarely contains actual cocaine. It is a synthetic drug cocktail, or a “chemical wildcard,” typically appearing as a pink-dyed powder, sometimes with a sweet, strawberry-like smell due to added flavorings and colorings. It is commonly found in nightlife settings, such as clubs and music festivals.
What substances are typically found in Tusi?
The exact composition of Tusi is highly unpredictable and varies significantly. There is no “exact recipe.” Common ingredients include ketamine, MDMA (ecstasy or Molly), caffeine, and methamphetamine. More alarmingly, fentanyl and other opioids are increasingly found in Tusi mixtures, as is xylazine. Other substances like synthetic cathinones, benzodiazepines, and other hallucinogens have also been detected.
Is Tusi the same as 2C-B?
No, Tusi is generally not the same as 2C-B, despite the phonetic similarity of their names. While Tusi’s street name came from the pronunciation of 2C-B, today’s Tusi rarely contains 2C-B. Instead, they primarily contain ketamine and other mixtures.
Why is Tusi called “pink cocaine” if it usually doesn’t contain cocaine?
The term “pink cocaine” is a misleading street name used because of the drug’s distinctive pink color and because some of its effects might partially mimic those of cocaine. The pink food coloring and sometimes a strawberry fragrance are added to enhance its appearance and marketing appeal.
Does Tusi often contain fentanyl?
Yes, fentanyl is increasingly found in Tusi mixtures. This is a grave concern because fentanyl is an extremely potent and often lethal opioid, making overdose a significant risk.
Why is the composition of Tusi so unpredictable?
Tusi is a concoction “cobbled together in uncontrolled environments” with no standard recipe. Its exact contents depend on who is producing it, often in small, homemade operations without quality control. This lack of standardization makes it a “mystery powder” where users cannot know what they are consuming or in what concentrations.
Can you test Tusi at home to know its contents?
Yes, you can use drug-checking kits, such as reagent tests, to help identify some components like MDMA, ketamine, and caffeine. Fentanyl test strips are especially important. However, these tests indicate presence, not concentration or exact amounts, and results can be difficult to interpret with complex mixtures. Professional drug-checking services or laboratories offer the most reliable analysis.
