There are multiple types of alcohol that humans use on a daily basis like methanol, isopropanol, ethanol, etc. The only type of alcohol that humans can safely drink is ethanol, produced by the fermentation of yeast, sugars and starches.
All alcohols including toxic ones can result in many physical irregularities and also may lead to death. Toxic alcohol refers to ethylene glycol, methanol, and isopropanol. Ethylene glycol and methanol may lead to severe acidosis, cardiac dysfunction and renal failure. Isopropanol is profoundly associated with CNS depression, depression in respiration rate, gastritis, etc.
Alcohols like methanol and isopropanol are basically used for different purposes like components of fuel, disinfectants, etc.
