Artificial intelligence (AI) is a rapidly developing technology in modern society, revolutionising education, health, communication and entertainment. The role of AI-based technologies such as social media algorithms, smartphone applications, online gaming platforms, Chat-bots and digital learning tools has increased significantly, particularly in the lives of adolescents and young adults.  Adolescence is a sensitive developmental stage, characterized by rapid mental emotional, and social changes, Consequently, AI can have both positive and negative impacts on adolescent mental health. The presents study aims to analyse the impact of AI on the mental health of college students. The sample included 300 college going graduate students aged 15-22 years. The DSS-Mental Health Scale was used for data collection. The data was analysed using percentage and mean methods. The results revealed that balanced and educational use of AI enhances students’ confidence, learning and social interaction, while excessive and uncontrolled AI use is associated with stress, anxiety, depression, sleep deprivation and social isolation. The study concludes that digital literacy, parental monitoring and counselling are crucial for protecting adolescents’ mental health when using AI.
