Cocaine and crack cocaine are psychostimulants that affect neurons containing dopamine in the areas of the brain known as the limbic and frontal cortex. When cocaine is used, it generates a feeling of confidence and power. However, when large amounts are taken, people "crash" and suffer from physical and emotional exhaustion as well as depression.
Cocaine increases and blocks the reuptake of dopamine, epinephrine, and serotonin. It affects dopamine the greatest out of these neurotransmitters.
Methamphetamine can do affect lots of brain structures, but the ones it affects the most are those that contain a chemical called dopamine.
Dopamine, Norepinephrine, and Serotonin.

True. Cocaine causes the sudden release in the brain of a neurotransmitter called dopamine. Source. Prentice Hall
Meth affects the central nervous system by flooding the brain with dopamine, the neurotransmitter responsible for feelings of pleasure and reward. Because meth provides the brain with an artificial source of dopamine, it can cause the neurotransmitter to fire abnormally. The brain will then chase that rush of dopamine, quickly facilitating addiction to meth. It may then be difficult for the brain to produce dopamine normally without the presence of meth.
Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate. Further down the line, this would cause muscle contraction through the release of Ca2+ from the SR.
Yes, meth can cause a clogged or runny nose.

The basic cause of choreic movements is overactivity of a neurotransmitter called dopamine in a set of structures deep within the brain known as the basal ganglia.
The immediate cause of Parkinson's disease or Parkinsonian-like syndrome is the lack of the neurotransmitter dopamine in the brain.
Most likely Dopamine which in excess accumulated in the brain cause schizophrenia.
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.

Acetylcholine
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
Not to all users, but it can.
Amphetamine and methamphetamine (the latter being more potent) cause the release of dopamine, serotonin and noradrenaline from axon terminals. Since the parts of the brain that contain the richest density of these cells are also involved in mood, perception, cognition and to a lesser extent, movement - this explains the cognitive and behavioral changes that occur following abuse of this class of drug.
It's not as simple as to which one specifically. Many neurotransmitters can cause euphoria, and or cause the release via modulatory action. However, dopamine is one of the most connected to euphoria. There are also Endocannabinoids, Gaba, Acetylcholine, Dopamine, Endorphins, Anandamide, and peptides.
Methamphetamine does cause myth mouth, and Ozzy Osborne is 65 years old. He was born on December 3, 1948.
