According to science and research, under circumstances, the brain releases and absorbs neurotransmitters such as dopamine, norepinephrine, and serotonin in to external signals and circumstances. Cocaine, , is a stimulant that temporarily blocks the brain’s ability to reabsorb the transmitters once they are released. As a , the transmitters accumulate in the synapses between nerve endings.
Accumulated norepinephrine and serotonin arouse the body’s adrenal system, while accumulated dopamine prolongs the transmission of signals between sending and receiving nerves. Adrenal activation heightened awareness, energy, and similar sensations, while prolonged nerve stimulation causes euphoria and mood elevation that are linked to the dopamine transmitter. The high, which develops in five to fifteen minutes in the case of powder cocaine and eight to twelve seconds in the case of crack, gradually as the supply of transmitters is reabsorbed. heroin, cocaine is not physically addicting. is, people who cease cocaine use do not suffer from withdrawal symptoms such as “the shakes”, nausea, and other physical symptoms.
