Memory storage difficulties cause significant verbal learning efficacy impairment in chronic cocaine users. Cognitive flexibility, learning, memory, attention and reaction time impairment can be seen in chronic cocaine users. Wisconsin card sorting test shows a strong correlation between deteriorations of moderate executive performance and the chronicity of cocaine and other drugs use [1-3].
