🥃 Methanol poisoning
Serious poisoning by methyl alcohol from counterfeit or home-made alcohol: early signs resemble intoxication, after 6–30 hours come abdominal pain and visual disturbance; urgent medical care is needed.
Methanol poisoning is a serious poisoning by methyl alcohol that enters the body from counterfeit or home-made alcohol. Methanol smells and tastes like ethanol, so it cannot be told apart without analysis. The first signs resemble mild intoxication, and the real symptoms appear later. This is an emergency: fast medical help is needed.
Why methanol is dangerous. According to the pathology service of Leeds Teaching Hospitals, methanol is a common contaminant in illegal alcohol. The body's enzymes turn it into formaldehyde and then formic acid, which causes severe acidosis. It is this acid that damages sight and the nervous system, rather than methanol itself.
Symptoms and timing. Within 30–120 minutes the drink acts like mild intoxication: drowsiness, confusion. After a hidden phase of 6–30 hours, dizziness, vomiting and severe abdominal pain appear. Visual disturbance can last up to a day. The consequences include blindness, coma, convulsions and death. The Leeds service cites cases of blindness from as little as 4 ml. Methanol is an industrial solvent, and occupational health regards it as hazardous.
Treatment and outbreaks. It is treated with ethanol or fomepizole, which block the enzyme, and with dialysis. The sooner, the better the chances. In 2025 the Pan American Health Organization warned of cases linked to adulterated drinks and called for stronger surveillance.
Why this matters to you. Buy alcohol only from legal trade, with a checked label and a seal. If poisoning is suspected, see a doctor at once. The WHO reminds: there is no safe level of alcohol.

Frequently asked questions
Is it true that methanol can be told apart by taste or smell?
No. The signs resemble intoxication from ordinary alcohol, and the drink can be identified only by laboratory analysis.
How quickly does methanol poisoning appear?
At first it resembles mild intoxication; the severe symptoms come after a hidden phase of 6–30 hours, and visual disturbance can be delayed by up to a day.
How is methanol poisoning treated?
With ethanol or fomepizole, which block the conversion of methanol into toxic substances, and with dialysis. It is treated only in hospital.
Where does methanol in alcohol come from?
From counterfeit and home-made drinks; PAHO linked cases in 2025 to counterfeit beverages.
What should you do if you suspect poisoning?
Call an ambulance at once and do not wait for vision symptoms, which come with a delay.
