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:
- Cerebral Cortex which plays a role in memory, thinking, perceptual awareness and consciousness
- Hypothalamus which governs metabolic processes such as appetite
- Amygdala which plays a role in emotions
- Hippocampus which is key to memory storage and recall
- Basal Ganglia which governs motor skills and learning
- Cerebellum which governs coordination and muscle control
- Brain Stem which controls many basic functions including arousing the vomiting reflex, blood pressure, heart rate and also 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.
