The AI-Driven Drug and Alcohol Detection System tackles substance abuse in schools using AI and sensor technology for real-time monitoring. Inspired by the "Say No to Drugs and Yes to Life" campaign, a pre-survey of 2,033 students from India and other countries revealed the need for proactive prevention. The system uses MQ-3 and MQ-9 sensors to detect harmful substances, with AI ensuring accurate alerts. By enabling early detection, promoting awareness, and fostering a drug-free environment, this initiative enhances school safety and student well-being for a healthier future.
