The pamphlet "Alcohol and Depressants" explains the effects of depressants, including alcohol. Depressants slow brain activity by increasing the release of inhibitory neurotransmitters like GABA, leading to effects such as sedation, decreased anxiety, and reduced heart rate. Alcohol, a legal depressant, causes short-term effects like impaired judgment, vomiting, and blackouts, while long-term use can result in alcoholism, liver disease, strokes, and cancer. Alcohol withdrawal can be life-threatening, causing seizures and heart complications. The pamphlet emphasizes the importance of safe usage and provides resources for treatment and further information.
