Alcohol

Alcohol is a depressant drug that slows down your body's central nervous system. While a small amount of alcohol may provide health benefits for some, drinking excessively can cause serious health issues. Problematic alcohol use can affect your concentration, speech, balance, vision, coordination, judgement, and overall health. Long-term problematic alcohol use can also lead to professional, personal, financial, and legal problems, any of which can affect your health.
