🥃 Methanol poisoning
Serious poisoning by methyl alcohol from counterfeit or home-made spirits: early signs resemble drunkenness, 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 a drink that contains it cannot be told apart without laboratory analysis. The first signs resemble mild drunkenness, 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 be delayed by 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 treatment starts, 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 an intact seal. If poisoning is suspected, call an ambulance or go to hospital at once. The WHO reminds: there is no safe level of alcohol.

Frequently asked questions
What are the first signs of methanol poisoning?
At first it resembles mild drunkenness: drowsiness and confusion within 30–120 minutes. The severe symptoms (dizziness, vomiting, abdominal pain) come after a hidden phase of 6–30 hours.
Can you tell methanol in a drink by taste or smell?
No. Methanol smells and tastes like ethanol, so the drink can be identified only by laboratory analysis.
How long can it take for sight problems to appear?
Visual disturbance can be delayed by up to a day. Do not wait for it: if poisoning is suspected, call an ambulance at once.
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, and the sooner the better.
Where does methanol in alcohol come from?
From counterfeit and home-made drinks. In 2025 the Pan American Health Organization linked reported cases to adulterated alcoholic beverages.
