Cocaine Addiction and Smartness
Taking cocaine alters the way one feels, and a scientific study has revealed that this is due to cocaine having an impact on the genes in the brain. The operations of these genes are altered when cocaine is taken, and this study will eventually lead to breakthrough in treating cocaine addiction.
Genes are not only something which passes on characteristics but actively regulate the behavior of various cells in our body all the time. Research conducted on mice has revealed that repeated doses of cocaine, causes the genes to switch on and off in an unusual manner, and causes the G9a protein to get suppressed. This protein stunts the growth of dendritic spines in the neuron cells, which is directly related to smartness. When G9a is suppressed, the growth of these spines increases thus affecting the IQ of a person. But this would suggest an increase in smartness, but this is not the case, as in cocaine which is considered a bad drug the learning process gets connected to a craving for more cocaine. The reverse has been proved in mice when their G9a levels were increased they had much less craving for cocaine.
As the G9a has an effect on the working of various cells it will still take a long time to develop something which can control addiction in humans.
