Lean — also called “purple drank” or “sizzurp” — is a recreational drink built around prescription cough syrup that contains codeine, an opioid, and promethazine, a sedating antihistamine. The syrup is mixed with a sugary soda and often a hard candy like a Jolly Rancher, which masks the bitter taste — and the drug it carries.
Lean has a notable place in pop culture, especially hip-hop, and one study found its use most concentrated among teens and young adults aged 13 to 21. Despite the playful image and the Styrofoam-cup aesthetic, lean is a potent opioid mixture with serious — sometimes fatal — risks. This article covers what’s in it, what it does, how addictive it is, how to spot use in teens and how to get help.
Lean is an opioid mixture and can cause life-threatening slowed breathing, especially when combined with alcohol. If someone is unconscious, breathing slowly or won’t wake up, call 911 immediately and give naloxone (Narcan) if it’s available. If you or someone you love is in crisis, call or text the 988 Suicide & Crisis Lifeline. The National Rehab Hotline at 866-210-1303 is for non-emergency information, support and referrals.
What Is Lean?
Lean is a homemade opioid cocktail, and it’s highly addictive. Its core ingredient is prescription cough syrup containing codeine — an opioid that, while it sounds mild, acts on the same receptors as drugs like morphine and heroin and should only be used under a doctor’s care. The syrup also contains promethazine, an antihistamine with strong sedative effects.
On their own, these syrups taste unpleasant, so people mix them with sweet soda (often Sprite) and sometimes candy. Lean is frequently consumed alongside other substances like alcohol and marijuana, which sharply increases the danger. Because it’s mixed by hand with no standard dose, there’s no reliable way to know how much codeine is in a given cup — a key reason overdoses happen.
What’s in Lean?
The classic recipe has a few parts:
- Codeine. A prescription opioid cough suppressant and pain reliever that produces euphoria and sedation, and depresses breathing at high doses
- Promethazine. An antihistamine and sedative that deepens the drowsiness and, critically, adds to the breathing-slowing effect
- Soda and candy. Added purely for taste and color, which makes the drink more appealing and easier to overconsume
Improvised versions are even riskier. Some swap in over-the-counter cough syrups containing dextromethorphan (DXM), and some “fake lean” has been found to contain fentanyl, a tiny amount of which can be fatal. Because there’s no quality control, you can’t be sure what’s in any given batch.
Serving size compounds the problem. Prescription codeine syrup is dosed by the teaspoon, but lean is poured by the cup — often several ounces at once, which can be many times a therapeutic dose before anything else is added.
What Are the Effects of Lean?
Lean’s effects come from the combined central nervous system depression of codeine and promethazine. Short-term, it can cause:
- Dangerously slowed heart rate and breathing
- Drowsiness, dizziness and impaired coordination — the “leaning” the drink is named for
- Nausea and, with too much, vomiting
- Blurred or double vision and trouble seeing in the dark
- Hallucinations, which can lead to risky behavior
- Memory and concentration problems
The Overdose Danger
The most serious risk is respiratory depression — breathing slowing to the point that the brain and organs don’t get enough oxygen, which can cause seizures, coma or death. Because codeine and promethazine both suppress the central nervous system, they amplify each other, and adding alcohol or other depressants makes a fatal overdose far more likely. Masking the taste with soda and candy makes it easy to drink too much before the effects fully hit.
The delay matters. Codeine taken by mouth takes time to reach peak effect, so someone who doesn’t feel much yet may keep drinking — and receive the full dose all at once, after it’s too late to stop.
How Addictive Is Lean?
Lean’s addictive potential is high. All opioids carry a high risk of dependence, and the same mechanism that drives the broader opioid crisis is at work here. Codeine activates the brain’s reward system, flooding it with dopamine; with repeated use, the brain adapts, tolerance builds, and a person needs more to feel the same effect — the cycle that leads to dependence. Promethazine isn’t a controlled substance, but its sedative effect reinforces the habit.
Signs of Lean Addiction
Physical and psychological signs that use may have become dependence include:
- A growing compulsion to drink lean
- Continued use despite wanting to stop
- Withdrawal symptoms like insomnia, sweating and agitation when not using
- Persistent cravings
- Social, occupational, legal or financial problems
- Riskier behavior and noticeable personality changes
If several of these sound familiar, it may be time to reach out for help.
Spotting Lean Use in Teens
Because lean is most common among teens and young adults, parents and caregivers are often the first line of defense. Warning signs include:
- Missing medications. Lean uses ingredients found in many medicine cabinets, so missing prescription or cold medicine is worth a conversation.
- Behavior changes. Persistent anger, withdrawal from activities and friends, sleeping excessively or unexplained weight loss.
- New slang. Terms like purp, sizzurp, Texas tea, dirty Sprite or purple drank.
- Physical traces. Empty cough syrup bottles, an unusual number of two-liter sodas or Styrofoam cups, or candy wrappers turning up together.
You may also hear “robotripping,” which refers to misusing over-the-counter cough medicine containing DXM.
Some encouraging context is worth holding alongside the concern. According to NIDA’s Monitoring the Future survey, teen misuse of prescription narcotics is at a historic low: among 12th graders, 0.6% reported past-year misuse of narcotics other than heroin in 2024, down from a peak of 9.5% in 2004. Most teens aren’t using these drugs. That doesn’t make lean safe for the ones who do — but it does mean a worried parent is dealing with an exception rather than a norm.
How Lean Addiction Is Treated
Because codeine is an opioid, lean dependence is treated much like other opioid use disorders — and recovery is very achievable with the right support. A treatment plan often includes:
- Medically supervised detox to manage opioid withdrawal safely
- Medication-assisted treatment (MAT) — medications like buprenorphine or naltrexone that reduce cravings and withdrawal
- Behavioral therapy, such as cognitive behavioral therapy, to address the patterns and triggers behind use
- Support for any co-occurring mental health concerns, since some people use lean to cope with anxiety, depression or stress
Quitting opioids abruptly can be rough and is safest with medical guidance, so reaching out before going it alone is wise.
Getting Past the Barriers to Help
Admitting a problem is hard, and hesitation, self-doubt and fear of stigma are common barriers to seeking treatment. Many people worry about being judged or about the impact on their job or reputation. But substance use disorder is a health condition, not a moral failing or a sign of weakness — capable, hard-working people face addiction and recover all the time. Trying to fight an opioid dependence alone can be dangerous, particularly because prescription opioid use can escalate toward stronger street drugs.

Frequently Asked Questions
- What Is Lean Made Of? Lean is a prescription cough syrup containing codeine (an opioid) and promethazine (a sedating antihistamine), mixed with soda and often hard candy. Some versions substitute DXM cough syrup or, dangerously, contain fentanyl.
- Is Lean Addictive? Yes. Codeine is an opioid, and opioids carry a high risk of dependence. Regular use builds tolerance and can lead to cravings, withdrawal and addiction.
- What Does Lean Do to You? It produces euphoria, heavy sedation and a dreamy, “leaning” feeling — but it also slows heart rate and breathing, which at high doses or mixed with alcohol can be life-threatening.
- Why Is Lean So Dangerous? Codeine and promethazine both depress the central nervous system, so together they can dangerously slow breathing. There’s no standard dose in a homemade mix, and adding alcohol or unknown ingredients like fentanyl raises the overdose risk even more.
- Can You Overdose on Lean? Yes. A lean overdose looks like an opioid overdose: very slow or stopped breathing, unresponsiveness, limpness, and blue or gray lips and fingertips. Call 911 immediately and give naloxone (Narcan) if it’s available. Naloxone reverses the codeine but not the promethazine, so emergency care is still essential.
- What Are the Street Names for Lean? Common names include purple drank, sizzurp, purp, dirty Sprite, Texas tea and syrup.
