What Is Mandrax? Inside South Africa’s Methaqualone Problem
What is mandrax? Inside methaqualone tablets, white pipe smoking, and addiction treatment at Changes Rehab Johannesburg.
Mandrax is the South African street name for tablets containing methaqualone, a sedative drug banned internationally in the 1970s but still produced in clandestine laboratories around the country. The drug acts as a central nervous system depressant.
It slows breathing and dulls consciousness to a level that can cause respiratory failure, especially when combined with cannabis or alcohol. South Africa has the highest mandrax use rate in the world, with the Western Cape reporting up to 29 percent of treatment seekers using it as a primary or secondary substance.
This article explains what mandrax is, what it does to the body and why coming off it safely requires medical detox at a facility like Changes Rehab in Johannesburg.
Where mandrax came from
Methaqualone was first synthesised in India in 1951 by chemists Indra Kishore Kacker and Syed Husain Zaheer. Pharmaceutical companies in Europe and the United States picked it up in the 1960s as a non-barbiturate sleeping aid, marketed under brand names like Quaalude in America and Mandrax in Britain and South Africa. The Mandrax tablet itself was a Roussel Laboratories product combining 250 mg of methaqualone with 20 mg of diphenhydramine, an antihistamine.
By the early 1970s the drug had become a global recreational problem. The 1971 UN Convention on Psychotropic Substances placed methaqualone under Schedule II, and South Africa banned it shortly after. Production never stopped, it simply went underground. Anthranilic acid, the main precursor needed to manufacture methaqualone, is cheap and widely available because it is also used to make dyes and perfumes.
What is mandrax made from?
A genuine pharmaceutical Mandrax tablet contained two active ingredients. The first was methaqualone, which produces the sedative effect. The second was diphenhydramine, an antihistamine that amplified the sleep response. Both drugs act on the central nervous system, which is why the combination was originally considered useful for insomnia.
Street mandrax produced in clandestine labs today rarely matches the original formulation. Purity ranges from 30 to 70 percent according to ENACT Africa research, and pills are routinely cut with whatever filler the manufacturer has at hand. Some seized batches have contained benzodiazepines or other sedatives instead of methaqualone. The lack of consistent dosing is part of why mandrax overdose remains a serious concern: a user has no reliable way of knowing what they are smoking.
What does mandrax look like?
Mandrax is sold as small, round tablets, usually scored down the middle so they can be split or crushed. Colours vary widely. Most tablets are off-white through grey to beige, though pink, blue, green, purple and black tablets have all been seized by SAPS. Each tablet is stamped with a logo that gives the drug some of its street names. The most common markings are “MX” and small images that look like flowers or lizards.
The drug is also seen as a loose tacky powder, brown to grey in colour, which is the form most often used as a cutting agent by heroin dealers. Parents and partners who find tablets they do not recognise can usually identify mandrax by the combination of small size, scored shape and a stamped logo.
The white pipe: how mandrax is smoked in South Africa
The way mandrax is consumed in South Africa is almost unique to this country. The standard method is the bottleneck or white pipe, in which a tablet is crushed, mixed with cannabis (dagga) and packed into the neck of a broken glass bottle. The mixture is then smoked, giving a rapid onset of effects within minutes rather than the 30 minutes or more an oral dose would take.
Smoking mandrax with cannabis is significantly more dangerous than swallowing it. Both substances act on the central nervous system. Cannabis adds psychoactive disorientation to the sedation that methaqualone already produces, and the effects of the two drugs together can last one to two hours per session. People who smoke white pipe frequently often develop a distinctive scar or burn stain on the palm of one hand from holding the heated bottleneck.
The smell is another identifier. White pipe produces a sweet, slightly chemical smell that lingers on clothing and in bedrooms long after the smoking session has ended. Family members who suspect mandrax use can often pick up the smell hours later.
Mandrax effects on the body and mind
The short-term effects of mandrax include:
- Heavy sedation
- Slurred speech
- Loss of coordination
- Slowed reaction time
- An euphoric calm that users describe as relief from anxiety or tension
Effects typically last around two hours when smoked and up to five hours when swallowed. Heavy doses or co-use with alcohol can cause respiratory depression, where breathing slows to a dangerous level. This is the mechanism behind most mandrax overdose deaths.
The long-term effects are more serious and develop quickly:
Tolerance builds in days, which means the dose required to get the same effect rises sharply within weeks.
- Chronic users develop physical and psychological dependence, with cravings that drive ongoing use even after major personal consequences
- Sustained heavy use damages the liver and kidneys
- Impairs memory and concentration
- Linked to anxiety, depression and in some cases psychotic symptoms
The polysubstance risk deserves a separate mention. Because the standard method of use mixes mandrax with cannabis, almost every mandrax user is also a regular cannabis user. The combination compounds cognitive impairment, and treatment for mandrax addiction usually has to address both substances at the same time. The Changes article on dagga covers the cannabis side of this picture in more detail.
Warning signs of mandrax use
Family members trying to work out whether a loved one is using mandrax can look for the following signs. Most regular users will show several of these.
- A scar, burn or dark staining on the palm of one hand, from holding the heated bottleneck.
- A sweet, slightly chemical smell on clothing, hair or in the bedroom, lingering hours after use.
- Slurred speech, unsteady walking and prolonged daytime drowsiness.
- Small round tablets, broken glass bottle necks or tablet fragments found in pockets, drawers or bins.
- Withdrawal symptoms (sweating, anxiety, tremor) when the person has not used for 12 to 24 hours.
- Sharp deterioration in school, work or family responsibilities, often with no clear cause.
- Increasing isolation, secrecy about whereabouts and a new social group the family does not know.
Seeing one or two of these signs is not proof of use. Seeing four or more, especially the hand scarring and the withdrawal pattern, usually means a conversation is overdue.
How long does mandrax stay in your system?
Methaqualone has a long elimination half-life of roughly 20 to 60 hours. In practical terms this means the drug can be detected in a urine test for two to four days after the last dose, in blood for several days and in hair tests for up to 90 days. The detection window stretches for heavy or chronic users because methaqualone accumulates in fatty tissue and releases slowly back into the bloodstream.
Standard workplace drug screens in South Africa do not always include methaqualone, but specific testing is available and increasingly common for employers in safety-sensitive industries. Court-ordered tests, custody hearings and rehabilitation programmes typically use the broader panels that catch it.
Mandrax withdrawal and why home detox is dangerous
Methaqualone produces a sedative-class withdrawal syndrome that is medically closer to alcohol or benzodiazepine withdrawal than to opioid withdrawal. Symptoms begin 12 to 24 hours after the last dose and peak around days two to three. The acute phase typically lasts seven to ten days.
Common symptoms include:
- Severe anxiety
- Agitation
- Insomnia
- Sweating
- Tremors
- Muscle cramps
- Nausea
- And in serious cases hallucinations or seizures.
The seizure risk is the reason home detox from mandrax is not safe. Sedative withdrawal can trigger generalised tonic-clonic seizures in heavy chronic users, with the same mechanism that makes alcohol withdrawal dangerous in late-stage drinkers.
A medically supervised detox uses tapered sedative medication to control the withdrawal response and prevent seizures, and provides 24-hour monitoring through the high-risk period.
Beyond the acute phase, many users experience post-acute withdrawal syndrome (PAWS), with low-grade anxiety, mood swings, sleep disturbance and cravings that can persist for weeks or months. PAWS is one of the major drivers of relapse in the first 90 days of recovery, which is why aftercare planning matters as much as the initial detox. The Changes medical detox page explains the supervision protocol in detail.
Treatment for mandrax addiction at Changes Rehab
Treatment for mandrax dependence follows the same evidence-based pathway as treatment for other sedative addictions.
- Primary care (medical detox). The first stage is medically supervised inpatient detox lasting around seven to ten days, during which withdrawal symptoms are managed pharmacologically and the patient is monitored for seizure risk and dual diagnoses. The Changes primary care facility in Northcliff has 16 beds, 24-hour clinical staff and an admitting doctor experienced in sedative-class withdrawal.
- Primary care (addiction treatment). After detox, the focus moves to addressing the addiction itself. Most mandrax users are poly-substance users, so treatment usually has to cover cannabis use alongside the mandrax dependence. Evidence-based therapies used at Changes include cognitive behavioural therapy, group work, family counselling and trauma-informed care for the underlying drivers of substance use. A standard inpatient programme runs for 21 days, which is covered as a prescribed minimum benefit under most South African medical aid schemes.
- Secondary care. Once primary care is complete, many patients move into secondary care at River Manor in Ruimsig, where the focus shifts to building the life skills, work routines and social structures that protect long-term recovery. The Changes assessment page explains how the admission process works, and the pre-authorise team handles the medical aid claim on the family’s behalf.
