⚡️🎙️ NEW - Marijuana contributes to Brain Damage: “It’s a Weapon of Mass Destruction,” Says Dr. Daniel Amen Dr. Daniel Amen, a psychiatrist and brain-imaging specialist, warns that marijuana use causes visible damage on brain scans, which he describes as producing a “toxic-looking brain.” He specifically highlights the cerebellum — the area at the back-bottom of the brain that contains about 50% of the brain’s total neurons despite taking up only 10% of its volume. ➥ Just as heavy alcohol use is notoriously toxic to the cerebellum, Dr. Amen states that marijuana is similarly damaging to this region. ➥ The cerebellum was once thought to be mainly responsible for physical coordination and balance. ➥ Modern research shows it also plays a critical role in thought coordination — how quickly and efficiently you process, integrate, and retrieve information. Because marijuana impairs cerebellar function, it literally slows down your thinking — making mental processing less sharp, less fluid, and slower overall. In Dr. Amen’s words, marijuana acts like a “weapon of mass destruction” to the brain.
