Why Does Weed make you Paranoid?
In the Journal of Neuropharmacology some scientists explained why the weed taken in can cause paranoia in the person. The scientists say that tetrahydrocannabinol when taken in low doses will make the person remain calm but high doses will have a contradictory effect.
Daniela Paralora studying on this aspect at the University of Insubria worked very hard to get an answer on why the weed makes us paranoid. She injected a little quantity of marijuana weed derived chemical into various parts of the rat brain. She watched for any behavioral change that might occur in the rats due to the drug. Her team learned that tetrahydrocannabinol (THC) showed positive effect on prefrontal cortex and ventral hippocampus. The drug was found to be causing anxiousness in the rats when it was injected into the basolateral amygdale region of the brain.
It is understood that there is loss of motor coordination when the weed is used in smoking. It will first result in weird hallucinations and later lead to paranoia. Before the person becomes paranoid due to the chemical present in the weed called THC, he will suffer from memory problems. Furthermore, he will have difficulty in learning, destruction of all the senses, lacking ability to think more, and the heart rate might be increased. All the above mentioned symptoms are only short term effects of the weed marijuana. The long term effects include cancer, affected lungs, and affected immune system.
Marijuana interferes with the communication between the neurons in the brain. To retrieve memory, one neuron should send signals to the other which is obstructed by marijuana through the cannabinoid receptors. This results in losing the memory. The cannabinoid receptors control the memory, concentration, thought and coordinated movement. The THC also affects the release of neurotransmitters.
The chemicals in the weed do not exhibit neuro-protective properties and give displeasure. They also reduce the cognitive function of the brain hence, make people lose their memory. The tetrahydrocannabinol stimulates mental disturbances and makes people experience relapse. As the weed affects mainly the central nervous system it causes paranoia.
