Cocaine’s Effect on the Brain

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.
