Methanol, a potent toxicant in humans, occurs naturally at a low level in most alcoholic beverages without causing harm. However, illicit drinks made from “industrial methylated spirits” [5% (v/v) methanol:95% (v/v) ethanol] can cause severe and even fatal illness.
Can we drink methyl alcohol?
Drinking just 25-90 mL (0.7-3.0 ounces) of methanol can be fatal without proper medical treatment. Since methanol is an industrial chemical, it should not be consumed in any quantity, just as people would normally not mix gasoline or other industrial chemicals into legitimate alcoholic beverages.

The admissible concentration of methanol in pure vodka is 100 mg/l of vodka; while in case of flavoured vodkas, the admissible concentration of methanol is 2 g/l of vodka.
How much methanol is toxic?
Blood methanol concentrations above 500 mg/L are associated with severe toxicity, and concentrations above 1500-2000 mg/L will lead to death in untreated patients5. The major toxic effects do not manifest until methanol has been metabolized to formic acid and this has accumulated to toxic levels.
What kind of alcohol is poisonous?
Although any alcohol can be toxic if ingested in large enough quantities, the term toxic alcohol has traditionally referred to isopropanol, methanol, and ethylene glycol.

What is methanol alcohol used for?

Does whiskey contain methanol?
Methanol is found naturally in fruit juice and distilled spirits such as whiskey, wine, and beer. A typical glass of wine contains a small amount of methanol, from 0.0041 to 0.02 percent by volume. … Methanol is much sweeter than ethanol, and even a small amount adds flavor to these beverages.
