The new nicotine trap: How vaping and new stimulants are hooking teens
After decades of declining teen smoking rates in Canada, a new wave of nicotine and stimulant products — from vapes to nicotine and caffeine pouches — is finding its way to young people. Canada now has one of the highest rates of youth vaping in the world, and the full health risks are still unknown. Dr. Nicholas Chadi sits down with Dr. Tea Rosic to unpack what's driving the trend, what the emerging products actually do to developing brains, and what parents, educators, and teens themselves can do about it.
Guest: Dr. Tea Rosic is a child and adolescent psychiatrist at CHEO and clinician investigator at the CHEO Research Institute in Ottawa. Her work focuses on the development, prevention, and management of co-occurring mental health and substance use disorders in young people.
