Matt Sandles created a PowerPoint presentation to educate his peers at CMU about the dangers of drinking alcohol and smoking. He feels strongly that students should not use drugs or partake in these activities. Over multiple slides, he outlines the health risks of alcohol and smoking, including alcohol poisoning, liver damage, various cancers, heart disease, and reduced life expectancy. He emphasizes that these substances are addictive and can ruin one's life. Sandles encourages students to make healthy choices and not drink or smoke just because their friends are doing it.
