Adulterated liquor, or liquor that has been tampered with in some way, often contains methanol, an alcohol more toxic than ethanol, or typical drinking alcohol. Adding methanol to distilled liquor allows sellers to increase the volume of liquid and its potential potency. Methanol poisoning can cause a variety of symptoms, including dizziness, confusion, drowsiness, headaches, and the inability to coordinate muscle movements. Even small amounts can be toxic. Symptoms of methanol poisoning tend to appear long after methanol has been consumed. There were reported such cases n several other countries including India, Turkey, Norway and the Czech Republic, resulting in hundreds of deaths and hospitalizations.
