Lean drink: What it is, what it does, and why it’s dangerous

 

Lean is a recreational mix of codeine cough syrup and a soft drink. The drink goes by several names, including purple drank, sizzurp, and dirty sprite, and it has a following in hip-hop culture that has helped normalise it among teenagers.

Lean is easy to get in South Africa, which is part of the problem. Most codeine cough syrups sit behind the pharmacy counter rather than needing a doctor’s prescription, and many households already have a bottle.

This article covers what lean is and what it does to the body, the risks that come with it, and how to recognise when someone has become dependent on codeine.

What is lean?

Lean is codeine cough syrup mixed with a soft drink, usually a lemon-lime one, and sometimes sweets for colour and flavour. Purple drank refers to its usual colour, though the shade depends entirely on the syrup used.

Two ingredients in the syrup do the work:

• Codeine, an opioid painkiller that the body converts to morphine
• Promethazine, an antihistamine that sedates and slows the central nervous system

Lean started in Houston in the 1960s and spread through hip-hop music. Several artists have died in circumstances linked to codeine syrup, and others have spoken publicly about their addiction, but the drink still carries a certain status in some circles.

What’s actually in lean, and where it comes from

Codeine appears in a long list of South African medicines, including cough syrups and combination painkillers. South African products that contain codeine include:

• Benylin with Codeine and Expectalin with Codeine (cough syrups)
• Myprodol, Mybulen, and Gen-Payne (painkillers)
• Adco-Dol and Tensodol (painkillers)
• Stilpane and Synaleve (prescription-only painkillers)

Broncleer, a codeine and promethazine syrup made in South Africa, is the one most associated with lean regionally. Broncleer is banned in Zimbabwe, where large quantities are smuggled each year.

How these products are regulated explains a lot. According to SAHPRA, codeine products are scheduled from 2 to 6, depending on the dose and what else is in them. Schedule 2 products sit behind the pharmacy counter and a pharmacist can sell them without a prescription. That makes a bottle of codeine syrup far easier for a teenager to obtain than most other opioids.

SAHPRA is tightening those rules through the Codeine Care Initiative, which would require pharmacies to record the ID number of every person buying a codeine product, so that repeat purchases can be flagged nationally. SAHPRA has said the system will be implemented during 2026.

What does lean do to you?

Codeine and promethazine together produce a slow, heavy sedation. People who drink lean describe a dreamy, detached feeling, with the body going loose and movement becoming difficult. The name refers to the way users end up leaning as coordination goes.

The effects usually begin within 30 to 60 minutes and can last several hours. Common short-term effects include:

• Drowsiness and heavy sedation
• Slurred speech and poor coordination
• Nausea and vomiting
• Itching and dry mouth
• Slowed breathing and heart rate
• Confusion and memory lapses

Because both drugs suppress the central nervous system, the sedation deepens as the dose rises, rather than levelling off.

Side effects of lean

Regular use brings a longer list of problems. Codeine causes constipation, which becomes severe with sustained use. Both ingredients disturb sleep architecture. Users often feel exhausted despite sleeping heavily. Weight changes are common, in either direction, because the syrup carries a large sugar load and appetite fluctuates.

Dental damage is a frequent and underestimated effect, caused by the sugar in both the syrup and the soft drink combined with a dry mouth.

Longer-term codeine use also brings tolerance, which means larger volumes for the same effect, and it can damage the liver, especially where the product also contains paracetamol.

Why there’s no safe way to mix lean

People search for how to make lean, and there’s no safe version of the answer. The dose can’t be controlled.

Cough syrups differ in how much codeine they contain. The same volume from two brands can carry very different amounts of codeine. Measurements are eyeballed rather than measured, the mixer hides the taste that would normally warn someone off, and the sedation builds slowly enough that people drink more before the first amount has taken full effect.

Where the syrup also contains paracetamol, the volumes involved can push someone past the safe daily limit long before they feel they’ve had too much. That risk is invisible while drinking.

The most serious risks

Slowed breathing: opioids suppress the reflex that drives breathing, and promethazine adds its own sedation. At high doses this can slow to the point of stopping, which is how codeine overdoses turn fatal.

• Mixing with other sedatives: alcohol, benzodiazepines, and sleeping tablets all depress the central nervous system too, and combined with lean the effect multiplies rather than adds.
• Seizures: promethazine acts on the central nervous system and, at high doses, can make a seizure more likely.

Signs of a lean overdose include:

• Very slow or irregular breathing
• Blue-tinged lips or fingertips
• Cold, clammy skin
• Being impossible to rouse

If you see those signs, call an ambulance immediately on 10177, or 112 from a mobile phone.

How addictive is lean?

Codeine is an opioid, and the body adapts to it the same way it does to any other. Tolerance develops within weeks of regular use, and the same volume stops working. Physical dependence follows, at which point stopping produces withdrawal.

Codeine withdrawal feels like a bad flu with anxiety layered over it:

• Aching muscles and sweating
• Runny nose and stomach cramps
• Nausea and insomnia
• Strong cravings

Withdrawal isn’t usually dangerous, but it’s unpleasant enough that many people drink again to make it stop, which is how the cycle entrenches itself.

There’s also a pattern specific to lean. People often start drinking it to take the edge off stress or low mood. As the effect wears off, mood drops below where it started, which creates a reason to drink again. Our article on prescription medication addiction covers how dependence develops with medicines that were never meant for recreational use.

Lean in South Africa

SAHPRA has described the use of lean in South Africa as having reached epidemic levels. Lean has a particular hold among school pupils, with reports of children as young as 10 using it. Three things drive this: the codeine syrup is cheap, it’s available without a prescription, and a bottle at home attracts no suspicion.

Over-the-counter and prescription medicines account for a small share of treatment admissions nationally, at 1% to 3% depending on the region, according to the SACENDU Research Brief for January to June 2025. The average age of those patients is 37, which is much older than the school pupils drinking lean. Teenagers rarely reach a treatment centre. Admissions data understates how widespread this is.

Signs of lean abuse

For parents and teachers, the signs are usually behavioural before they’re physical. Look out for:

• Cough syrup bottles in a bedroom or bag, or medicine disappearing from the house
• Buying cough mixture when nobody is ill
• Drowsiness, slurred speech, and poor coordination
• Constant thirst, dry mouth, and sudden dental problems
• Constipation and nausea
• Falling behind at school, or losing interest in sport and friends
• Irritability and aggression between doses

One sign alone means little. Several of them together, over weeks, call for a conversation.

Getting help for codeine and lean addiction

Codeine dependence responds well to treatment, and the earlier someone starts, the simpler it is. Because withdrawal is physically uncomfortable, most people do better with medical support than by stopping abruptly on their own.

Houghton House is a licensed psychiatric hospital in Johannesburg. Treatment usually begins with medically supervised detox to manage withdrawal, followed by our inpatient drug rehab programme or outpatient care, depending on how severe the dependence is.

Substance use disorders are prescribed minimum benefits in South Africa, which means every registered medical aid must cover addiction treatment. Our admissions team can check your cover on 011 787 9142, 24 hours a day.

If private treatment isn’t an option, our list of free, government, and subsidised rehabilitation centres covers all nine provinces, and our guide to addiction support groups lists peer meetings you can attend at no cost.

Frequently asked questions about lean

What colour is lean?

Usually purple. That colour is where the name purple drank comes from. The shade comes from the cough syrup rather than the drink, and lean made with another syrup can be red, green, or clear. Sweets are sometimes added for colour, which means appearance tells you nothing about strength.

How long does lean stay in your system?

Codeine shows up in a urine test for roughly 1.5 to 4 days after a single dose, and for about a week in regular users, according to a review of drug detection times. Blood tests detect it for one to two days, and hair for far longer. The effects themselves wear off within several hours, long before the drug leaves the body.

Is lean an opioid?

Codeine, the active ingredient, is an opioid, and the body converts it to morphine. That’s why lean carries the same risks as other opioids, including tolerance, dependence, and slowed breathing at high doses.

Is lean illegal in South Africa?

The medicines used to make lean are legal and sold in pharmacies. What’s regulated is how they’re supplied: codeine products are Schedule 2 and higher, which means a pharmacist must dispense them, and higher-strength versions need a prescription. Buying syrup to drink recreationally, or going from pharmacy to pharmacy to build a supply, falls outside how these medicines may lawfully be supplied.

Is lean addictive?

Yes. Codeine is an opioid, and regular use leads to tolerance and physical dependence, often within weeks. Many people who become dependent started with an ordinary cough syrup rather than anything illicit.

What does lean feel like?

Users describe heavy sedation, a floaty detachment, and difficulty moving normally. Nausea and itching are common alongside it. As the effect fades, mood often drops lower than it was beforehand, which is part of what pulls people back to it.
