To the editor Cocaine is widely recognized as a highly addictive drug that can cause severe consequences for physical and mental health, and its damage to the neurovascular system, cognitive decline, and behavioral dysfunctions are well-documented (UNOCD, n.d.). Cocaine acts on the brain by inhibiting the reuptake of neurotransmitters, especially dopamine, resulting in a positive reinforcement, and a pleasant sensation that increases its consumption (Planeta et al., 2013). However, in high concentrations, dopamine is neurotoxic, causing neurodegeneration, and consequently, cell death (Ben-Shachar et al., 2004;Planeta et al., 2013). Craving for cocaine also changes dopamine neurotransmission due to the reduction of D 2 receptor expression (Martinez et al., 2004) and the condition can cause neuroadaptations by inhibiting GABA (Gamma-aminobutyric acid) release that, in turn, affects the dopaminergic system (Sofuoglu & Kosten, 2005). Moreover, modifications in the composition of AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate) receptor subunits, enhancing the strength of excitatory synapses, characteristic of prolonged period of abstinence.
