When a large quantity of ethanol is consumed, it tends to slow down metabolic processes.
→ Moreover, it depresses the Central Nervous System (CNS). This results in lack of coordination, mental confusion, drowsiness, lowering of the normal inhibitors and finally individual becomes unconscious and lethargic.
→ The individual may feel relaxed but does not realised that his sense of judgement, sense of timing and muscular coordination have been seriously impaired.
→ Instead of ethanol, intake of methanol in very small quantities can cause death; because methanol is oxidised to methanal in liver. Methanal reacts rapidly with the components of cells and coagulates the protoplasm.
→ Methanol also affects the optic nerve and causes blindness.
→ Thus, consumption of alcohol is dangerous to living beings.
