Marijuana

How does marijuana affect the brain?

The human brain is a complex organ that is responsible for other parts of the body and its ability to do things.  Marijuana affects the brain in the following areas:

  • 1. Cerebral Cortex which plays a role in memory, thinking, perceptual awareness and consciousness
  • 2. Hypothalamus which governs metabolic processes such as appetite
  • 3. Amygdala which plays a role in emotions
  • 4. Hippocampus which is key to memory storage and recall
  • 5. Basal Ganglia which governs motor skills and learning
  • 6. Cerebellum which governs coordination and muscle control
  • 7. Brain Stem which controls many basic functions including arousing the vomiting reflex, blood pressure, heart rate and plays a role in pain sensation, muscle tone and movement


Because marijuana plays a great role in storing, retaining and recalling memories it is proven that long term use of marijuana lowers an individual's IQ by 8 points.
