Youth vaping and cannabis co-use: Policy failure or mental health crisis?

A silent storm is brewing among South African youth – a rapid rise in vaping and cannabis co-use.

Drawing on new national survey data and global trends, this lecture explores the complex interplay between substance use, policy, and mental well-being, while raising urgent questions about how society and health systems should respond to protect the next generation.
