Acetylcholine( Ach) is a neurotransmitter.In parkinsonism there is a marked drop of dopamine level and Ach is indirectly associated with dopamine. there is a constant balance between dopamine and Ach.When Ach level increases ,dopamine level falls leading to parkinsonism like symptom
The could be a stress / trauma related impairment of the dopamine system that results in a reduced capacity to experience pleasure and correlates with addiction. The dopamine recepters are unable or reduced in their ability to reuptake dopamine and thus a flood of dopamine becomes necessary in order to feel any level of pleasue. That's my best guess.

Schizophrenia is often associated with a high level of the neurotransmitter dopamine.
Tonic dopamine activity in the brain's reward system is a steady, baseline level of dopamine release, while phasic dopamine activity is a rapid and transient increase in dopamine release in response to rewarding stimuli.
Dopatone is a dietary supplement which helps to increase the level of dopamine in your system. Dopamine is a natural body chemical which give us our basic good feeling inside. When the level of Dopamine is lowered, it give us a uneasy feeling,anixety,depression etc.

Crystal methamphetamine acts by increasing the release of neurotransmitters like dopamine, norepinephrine, and serotonin in the brain. It binds to the dopamine transporter proteins on nerve cells, preventing the reuptake of dopamine and leading to increased levels of dopamine in the brain. This surge in dopamine results in the intense feelings of euphoria and increased energy associated with crystal methamphetamine use.
Dopamine levels drop below normal after sobering up from a night of drinking. This contributes to hangovers.
"Abuse" means you're over the line by definition. Drugs by themselves are used medically and recreationally (mainly Caffeine, Nicotine, Alcohol), and you can abuse them too. Good answer, if you are at drug abuse, you are pass the safe level. One last thing, there is no safe level for drug abuse, don't kid yourself!
Let us use an example. Dopamine receptors in the brain are influenced in variance amounts by the genes recipe for brains, modulated by development and the environment. That is some people have more, or less dopamine receptors in their brain. Dopamine is a reward neurotransmitter and its effect is modulated by the amount of receptor sites it has. They have found that those with very few receptor sites take more reward giving risks to keep the level of dopamine high in their brains; to feel the reward. Those with normal numbers of receptors do not show such risky behavior on average. Thus, genes have this to do with these peoples behavior and this illustration just shows a little piece of this puzzle.

research suggests that the gastrodia tuber has analgesic and sedative effects because the compounds in it decrease the level of dopamine in the brain.
