Why cannabis is bad for you: World first study identifies exactly how the drug stunts your brain development

To do away with excess synapses, neural cells release cannabinoids.
Cannabinoids are a diverse chemical compound in our cells that repress parts of the brain.
These chemicals are the active agent which give weed its intoxicating effect.
Testing mice, the researchers found that smoking or eating cannabis has the same effect: hampering neuron projections.
SO HOW DOES IT WORK?
Our memory is strengthened by different regions of the brain working in unison.
The thalamus and cortex operate at the same time, building connections and strengthening the synapses (the junction between nerve cells).
As the brain develops, projections from the thalamus to the cortex are spread further.
These before-and-after images show how cannabis suppresses thalamocortical projection
In the new study, Osaka's researchers discovered that, at a certain point, the synchronized activities weakened all but some synapses.
As a result, they eliminate unnecessary projections to enable more systematic ones.
As the synapses are weakened, endogenous cannabinoid is released from neural cells via these synchronized activities.
This leads to a regression of unnecessary neuron projections.
The researchers confirmed that the same regression happens when cannabinoid was taken in externally - i.e.: when someone smokes a joint.
