Final answer:
Moderate alcohol consumption has positive effects on mood and social interaction, while excessive alcohol consumption can lead to negative consequences such as impaired coordination, aggressive behavior, and increased health risks.
Step-by-step explanation:
Moderate alcohol consumption: The positive effects of moderate alcohol consumption include an enjoyable state of mind and facilitating pleasurable social interaction. It can also contribute to a longer lifespan compared to abstaining from alcohol.
Excessive alcohol consumption: On the negative side, heavy drinking can lead to lack of coordination, blurred vision, impaired judgement, and aggressive behavior. It is associated with a higher risk of road accidents, job loss, family disruption, memory loss, physiological disorders like cirrhosis of the liver, and an increased likelihood of certain forms of cancer.
Acute effects of alcohol: Alcohol use is associated with feelings of euphoria at low doses, but as the dose increases, sedation and decreased alertness can occur. Excessive alcohol use can result in a complete loss of consciousness, difficulty remembering events, and the risk of fetal alcohol spectrum disorder.
Long-term effects: Excessive alcohol consumption can have serious long-term effects on the excretory system, including liver and kidney disease. Chronic alcohol abuse can also lead to abnormalities in blood ion concentration and acid-base balance, putting the individual at risk.
