Studies show cannabis may slow cognitive growth in adolescents, while Australia’s ARIA enforces stricter rules on AI-generated music amid industry concerns; both developments underscore the importance of navigating technological and health risks for young people.
Teenagers who begin using cannabis may be at greater risk of slower development in memory and other thinking skills, according to researchers at the University of California San Diego. The study, published in Neuropsychopharmacology, tracked more than 11,000 participants in the Adolescent Brain Cognitive Development study, the largest long-term look at brain development in young people in the United States. The researchers found that teens who used cannabis tended to keep improving, but at a slower pace than those who did not use it, particularly in memory, attention, language and processing speed.
The findings do not suggest that every young user will experience the same outcome, but they do add to long-running concerns about cannabis and the adolescent brain. Because the teenage years are a critical period for cognitive development, the researchers said the slower gains seen in users could matter over time, especially when use begins early.
At the same time, Australia’s recorded music industry is moving to draw a firmer line around artificial intelligence. The Australian Recording Industry Association has said that tracks wholly generated by AI will not be eligible for its official charts or for ARIA awards. The change follows controversy over an AI-remixed version of Madonna’s “Like a Prayer”, which reached number two on the charts and, according to reports, spent 16 weeks in the Top 20.
ARIA has said AI can still be used in a supporting role, but a human creator must remain the main creative force behind the work. The decision reflects a broader effort by the music industry to protect artists’ rights and respond to growing concern that generative AI can copy or repurpose human-made material without permission.
For parents and caregivers, the message is fairly direct: conversations about risk still matter. The cannabis research offers another reason to talk with teenagers about substance use in concrete terms, while the ARIA decision shows how quickly technology is reshaping creative industries and the rules around them. In both cases, the central issue is the same: how to draw a line between innovation and harm.
