Marijuana Lowers Brain Blood Flow, Doesn’t Prevent Alzheimer’s
Contrary to popular belief, Dr. Amen states that marijuana reduces blood flow across all brain regions, ages the brain, and increases risks of psychosis and mental health issues in teens. He debunks claims that it prevents Alzheimer’s, noting low blood flow is a top predictor of the disease.
- Marijuana reduces blood flow in all areas of the brain.
- It increases risk of psychosis and mental health struggles in vulnerable individuals.
- It does not prevent Alzheimer’s—low blood flow is a key predictor, which marijuana worsens.
“Marijuana is bad for the brain... every area of the brain is lower in blood flow.”
“Absolutely not... marijuana lowers blood flow to the brain.”
