Alcohol: How Much Is Actually Too Much?

South Africa ranks among the highest countries in the world for alcohol-related harm. The South African Medical Research Council (SAMRC) estimates that alcohol contributes to roughly 7% of all deaths in the country — that is about one in 14 South Africans who die each year from a cause directly or indirectly linked to drinking. Yet most people who drink regularly have never seen the Department of Health’s low-risk guidelines, let alone know what a “unit” of alcohol looks like in a brandy-and-Coke or a dumpie of Castle.

This piece fixes that.

What the SA guidelines actually say

The Department of Health and the South African National Council on Alcoholism and Drug Dependence (SANCA) align their guidance broadly as follows: no more than 2 standard drinks per day for men, and no more than 1.5 standard drinks per day for women, with at least two alcohol-free days per week.

That works out to a weekly maximum of roughly 14 drinks for men and 10 drinks for women — but those numbers assume you spread consumption evenly, which almost nobody does.

One SA standard drink contains 12–14 g of pure alcohol. In practical terms, that equals:

• 340 ml of regular beer (roughly one dumpie of Castle or Black Label at 5%)
• 150 ml of wine (a small to medium restaurant pour)
• 45 ml of spirits (a standard tot of whisky, brandy, or vodka)

Most home pours are larger. A generous brandy-and-Coke at a braai is often closer to two standard drinks. A 750 ml bottle of wine contains roughly five standard drinks, not three or four as many people assume.

Why ‘I only drink on weekends’ doesn’t protect you

This is where the guidelines get misunderstood most often — and it matters enough to name directly.

The popular belief goes: if you stay sober Monday to Friday, drinking 10 or 12 beers across a Saturday night is roughly equivalent to spreading those drinks through the week. It is not. Binge drinking — defined in SA public health practice as consuming five or more drinks in a single session for men, or four or more for women — triggers a separate set of harms regardless of your weekly total.

A single binge episode raises blood alcohol concentration fast enough to impair judgment, slow reaction time, and increase injury risk in ways that gradual consumption does not. More importantly, repeated binge sessions — even monthly — are independently associated with increased risk of hypertension, cardiac arrhythmia, and liver inflammation. Given that South Africa already carries an enormous burden of hypertension (nearly 1 in 3 adults, according to the Heart and Stroke Foundation SA), adding binge-related cardiovascular stress is a particularly dangerous combination locally.

The SAMRC also flags that heavy episodic drinking is disproportionately common among South African men aged 15–34, the same demographic most affected by trauma, road-traffic injury, and interpersonal violence — all of which alcohol directly worsens.

What alcohol does to your liver — and when to worry

Your liver can process roughly one standard drink per hour. Consistently drinking above that rate means your liver is always working in arrears. Over time, this produces a predictable progression: fatty liver disease (often symptomless), then alcoholic hepatitis (which can be acute and life-threatening), and ultimately cirrhosis — irreversible scarring that the liver cannot recover from.

The threshold for significant liver risk sits at roughly 30 g of pure alcohol daily for men (about 2–3 standard drinks) and 20 g daily for women (about 1.5 standard drinks) over sustained periods. Women reach toxic liver thresholds at lower doses because of lower body water content, lower levels of the enzyme alcohol dehydrogenase, and hormonal factors affecting alcohol metabolism.

In South Africa, liver disease is compounded by the country’s HIV and TB burden. People living with HIV on antiretroviral therapy (ART) face significant added risk: alcohol interferes with ART adherence, accelerates HIV-related liver damage, and interacts with some ARV drugs — particularly nevirapine and ritonavir-boosted regimens. If you are on ART, speak to your clinic doctor or pharmacist before drinking at any level; this is not a conversation to skip.

No local equivalent of a nationally published SA liver-disease prevalence figure exists for alcohol-specific cirrhosis in isolation, but the SAMRC’s Burden of Disease research consistently identifies liver cirrhosis among the top contributors to premature mortality in South African men.

The rand cost of drinking at the limit

Understanding the financial reality of drinking at the guidelines’ upper end is useful. At current retail prices (mid-2025):

• A 750 ml bottle of mid-range wine (5 standard drinks): approximately R90–R130
• A six-pack of 340 ml beers (6 standard drinks): approximately R80–R110
• A 750 ml bottle of brandy (roughly 17 standard drinks at standard tots): approximately R160–R250

A man drinking at the weekly upper limit of 14 standard drinks — using mid-range beer as a baseline — spends roughly R180–R260 per week, or R9,000–R13,500 per year, before factoring in mixers, bar mark-ups, or the cost of any alcohol-related health event. That figure climbs sharply if drinking exceeds guidelines.

Alcohol and cancer: the scare that isn’t a scare

You may have seen headlines about alcohol and cancer and assumed the risk was overstated. It was not misapplied — it was, if anything, under-communicated.

The World Health Organization classifies alcohol as a Group 1 carcinogen (the highest category, shared with tobacco). Even moderate drinking — within the limits described above — is associated with increased risk of cancers of the mouth, throat, oesophagus, liver, colon, and breast. The breast cancer risk figure is concrete: for every 10 g of alcohol consumed daily (less than one standard drink), breast cancer risk rises by approximately 7–10% in relative terms. To anchor that: in a population of 1,000 women with a 10% baseline lifetime breast cancer risk, that translates to roughly 7–10 additional cases per 1,000 over a lifetime of daily drinking at that level.

No SA-specific cancer-and-alcohol incidence data has been published at the time of writing; the figures above come from the International Agency for Research on Cancer (IARC) and apply globally.

Accessing help: public and private pathways in SA

Public sector: If you are concerned about your drinking, your first stop is a community health centre (CHC) or public clinic. Nurses at primary care level can do a brief alcohol screening using the AUDIT-C questionnaire and refer you to a social worker, counsellor, or district hospital for more intensive support. SANCA operates 19 treatment centres nationally and accepts public-sector referrals.

Private sector: A GP consultation to discuss alcohol use costs roughly R600–R1,200 at a private practice without medical aid, or is covered under medical aid at PMB (Prescribed Minimum Benefit) level if a substance use disorder is formally diagnosed. Outpatient counselling through a registered psychologist runs approximately R900–R1,500 per session; some medical aids cover six to twelve sessions annually under mental health PMBs — check your plan’s schedule of benefits.

Barriers and workarounds: Load-shedding disrupts scheduled telehealth sessions; if your provider offers WhatsApp or SMS-based follow-up, use it. Transport costs to SANCA centres can be significant in rural areas — ask at your CHC whether a mobile health outreach team covers your area.

SADAG (South African Depression and Anxiety Group) runs a substance use support line at 0800 567 567 (toll-free, 24 hours).

Bottom line

– Stick to no more than 14 drinks a week (men) or 10 (women), with at least two alcohol-free days — those are the SA Department of Health limits.

– Count your actual pours. A generous home tot or large restaurant wine glass is often two standard drinks, not one.

– Weekend binge drinking is not a safe workaround — five or more drinks in a sitting carries its own independent health risks.

– If you are on ART or managing hypertension or diabetes, ask your doctor or pharmacist specifically about alcohol — the interaction risk is higher than average in SA.

– For support, call SADAG on 0800 567 567 or visit your nearest CHC for an AUDIT-C screening.

When to see a doctor

See a GP or clinic nurse if: you regularly drink more than the guidelines above; you notice yellowing of the skin or eyes, persistent nausea, or upper abdominal pain (possible liver symptoms); you find it difficult to go a day without alcohol; or you are on chronic medication, including ARVs, and drink any amount. Your nearest public clinic can screen you at no cost.
