It reduce BP by causing dilation of blood vessel. The prolonged use of alcohol produce hypertension and CHD .it stimulates acid secretion in stomach and causes gastritis and peptic ulcers , alcohol increase urine output by decreasing the secretion of" ADH" . Heavy drinks become dehydrated.

Thirst, dry tongue and hangover are associated with effect of alcohol. The main target organ of alcohol is live .in liver the alcohol changes into acetaldehyde which is utilize by the hepatic cell for energy production. Fatty acid start accumulation and fatty liver symptoms develop .the fibrous tissue makes liver in active and the cracks develop. This condition of liver is called cirrhosis it is a social evil and involves lot of expenditure. The inhibition in the society are diminished and person may start anti social activity .

Alcohol and driving do not go together as alcohol
1 reduced ability of judge distance and alertness.
2 It causes blurred vision and reduces visual field.
3 It increases reaction time and coordination between the organs is reduced . that’s why the drinking and driving should not be done.
