Cannabis and Traumatic Brain Injury (TBI)

TBI, or traumatic brain injury usually results from a violent blow or jolt to the head or body that causes damage to your brain. An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury. A traumatic brain injury can happen to anyone, at any time. Around 36,000 people in New Zealand suffer from traumatic brain injuries every year. Symptoms of a TBI may include headaches, vomiting or nausea, seizures, sleepiness, slurred speech, or weakness or numbness in the limbs. Most traumatic brain injuries in New Zealand are caused by recreation or playing a sport (this makes up 20% of injuries), falls, using machinery, accidents while driving, and assault.
