Did you know that a study in New Zealand has shown that there is loss of intelligence when youth consume marijuana during adolescence? Indeed, although adolescents leave drugs this intellectual deficit persists. This is during adolescence are forming neural connections, the prefrontal cortex, regions critical for learning, planning and memory, these regions can absorb the active ingredients of the herb. In conclusion, different studies have reflected on the reduced intellectual capacity on people who use these drugs such as marijuana and cannabis, as well as limiting future opportunities, reducing learning ability and memory, and brain training may become more complicated, because the level of attention decreases.
