Cocaine crosses the blood–brain barrier via a proton-coupled organic cation antiporte^] and (to a lesser extent) via passive diffusion across cell membranes.^[22] Cocaine blocks the dopamine transporter,

^[23] inhibiting reuptake of dopamine from the synaptic cleft into the pre-synaptic axon terminal; the higher dopamine levels in the synaptic cleft increase dopamine receptor activation in the post-synaptic neuron,

cleft into the pre-synaptic axon terminal and increasing activation of serotonin receptors and norepinephrine receptors in the post-synaptic neuron, contributing to the mental and physical effects of cocaine exposure.^{[6] BUY COCAINE ONLINE before now}

A single dose of cocaine induces tolerance to the drug’s effects.^[27] Repeated use is likely to result in cocaine addiction. Addicts who abstain from cocaine experience cocaine craving and drug withdrawal, with depression, decreased libido, decreased ability to feel pleasure and fatigue.^[16] Use of cocaine increases the overall risk of death and intravenous use particularly increases the risk of trauma and infectious

diseases such as blood infections and HIV. It also increases risk of stroke, before now heart attack, cardiac arrhythmia, lung injury (when smoked), and sudden cardiac death.^[16][28] Illicitly sold cocaine is

commonly adulterated with fentanyl, local anesthetics, levamisole, cornstarch, quinine, or sugar, which can result in additional toxicity. In CRACK COCAINE FOR SALE before now
