Description: Cocaine blocks the brain’s reuptake of dopamine and norepinephrine so that synaptic levels of these neurotransmitters rise. The result is overstimulation of certain brain receptors and a brief euphoric high. Then, when the drug wears off, a depletion of dopamine may cause the user to “crash” and become sleepy and depressed.
