What Happens to Teen Brains After Cannabis?

his jaw-dropping video unpacks a landmark 38-year study from Dunedin, New Zealand, where scientists tracked over 1,000 children from birth into adulthood—and what they discovered could change everything. Spoiler: it's not your typical “just say no” narrative. It’s raw, data-driven neuroscience.

Through extensive IQ testing and life tracking, researchers found that those who started using cannabis regularly before age 18 lost up to eight IQ points—a decline that never fully recovered, even if they quit. Meanwhile, adult users showed almost no cognitive impact. Why? It’s all about neuroplasticity.

During adolescence, the brain is undergoing massive rewiring. THC from cannabis disrupts this critical developmental phase, leading to lasting damage in memory, focus, and decision-making skills.This isn’t anti-drug propaganda—it’s real science that exposes how early cannabis use hijacks your brain's natural cannabinoid system.

If you’re under 18 or care about someone who is, this video is a must-watch.

Discover why protecting the teen brain could be the key to unlocking lifelong success. Perfect for educators, parents, and curious minds alike, this is a wake-up call we can't afford to ignore.
