Detailed explanation-1: -Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.
Detailed explanation-2: -Additionally, drugs can prevent the reuptake of neurotransmitters into the presynaptic terminal. Cocaine blocks the dopamine transporter, which results in increased action of dopamine in the synapse. Figure 14.3. Drugs and toxins can alter neurotransmitter degradation and reuptake into the presynaptic terminal.
Detailed explanation-3: -Some street drugs, including cocaine, methamphetamine, heroin, marijuana, nicotine, alcohol, and prescription painkillers, can alter a person’s behavior by interfering with neurotransmitters and the normal communication between brain cells.
