Some speed it up while others slow it down.
True. Alcohol and other drugs can affect nerve cells in the brain by interfering with neurotransmitter function, altering communication between neurons, and impacting decision-making, behavior, and emotions. This can lead to both short-term and long-term changes in brain function.
Drinking alcohol, even in excessive amounts, does not kill brain cells. However, alcohol slows our reactions, respiration, heart rate, etc.
Only the nerve cells, yes.
Neurotransmission
Alcohol can disrupt communication between nerve cells by affecting neurotransmitter levels and decreasing the ability of nerve cells to function properly. Chronic alcohol consumption can damage nerve cells and lead to issues with memory, cognition, and coordination.
Drugs are chemicals. They work in the brain by tapping into the brain's communication system and interfering with the way nerve cells normally send, receive, and process information. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter. This similarity in structure "fools" receptors and allows the drugs to lock onto and activate the nerve cells. Although these drugs mimic brain chemicals, they don't activate nerve cells in the same way as a natural neurotransmitter, and they lead to abnormal messages being transmitted through the network. Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels. The difference in effect can be described as the difference between someone whispering into your ear and someone shouting into a microphone.
The firing rate in a nerve refers to the frequency at which action potentials are generated and conducted along the nerve. This firing rate can vary depending on the type of nerve and the intensity of the stimulus being received.

a nerve tends to refer to a group of nerve cells.
Connector nerve cells connect the sensory nerve cells with motor nerve cells and allow for decision making.
Occipital nerve headaches are caused by the firing of the occipital nerve either as the result of a process that disturbs the nerve or as the result of a chronic pain condition that causes spontaneous firing of the nerve pathways resulting in pain.
