The range of dopamine in the brain that is considered 'normal' is from 70mcg to 350mcg.
http://www.scienceclarified.com/Io-Ma/Marijuana.html A new study finds that it does in fact increase dopamine , This is why i get so bloody groggy when i smoke large amounts of dope! above answer is so wrong... Interference with dopamine production is the chemical basis of addiction in the use of alcohol, amphetamines, cocaine, nicotine, opiate compounds, and other powerful addictive substances. Clinical studies show that cannabis is dissimilar to classic addictive drugs in that it does not significantly interfere with dopamine production in the "pleasure centers" of the brain, according to the Office of Technology Assessment after ten years of research.

If you mean "How much percentage of water does a human brain have?", the answer is about 77-78%.
The stimulation of dopamine production in the brain, or the imitation of its action, is one of the primary ways that drugs and addictive activities please us. Likewise, a shortage of dopamine is one of the causes of withdrawal. However, it would be more correct to say that we become addicted to the things that stimulate it, since dopamine itself is a normal part of our brain chemistry. To put it simply, yes. But technically, no. Say you're taking crack. Whenever you take it, you get a rush of domapine and other effects (reduced pain, lightheadedness). The dopamine level is so high that the body raises it's "expected level" of dopamine, so not taking crack makes you depressed, and causes the opposite of the other effects (body pain, headaches). In a way, this causes the addiction. If you were to take actual, synthetic dopamine, and take it often, you couldn't actually get addicted to it, but you would be depressed without it.
catnip triggers the dopamine in cats because the brain experiences euphoria when the cat starts to eat the catnip, and the cat likes the food, so the dopamine levels rise in the brain triggering the brain activity to rise. you should most likely give your cat a small saucer amount of catnip.
not much more than I can.
There isn't an opposite of ADHD par say. Schizophrenia would be the chemical opposite of ADHD since it involves too much dopamine in the brain as opposed to little dopamine in individuals with ADHD.

ADHD is a grouping of behavioral or mental patterns: a mental disorder. It describes behavior but not an underlying cause. It’s like how a pain in your leg does not describe the cause of the pain. Is it broken, burnt or infected? It looks like there are more ways to get ADHD: genetic, environmental and both. We just don’t know exactly what happens. Some recent Dutch research seems to indicate that for 80% of children with ADHD, most symptoms can be taken away by a personalized diet. Full speculation mode - A big reason might be: The brain of someone with ADHD likes some food or activities too much. When consumed the brain makes so much dopamine that the body adapts and starts breaking it down faster. As a result normal dopamine production gets broken down faster too. On average you have to little dopamine in your brain, which is the stuff that makes you concentrate.
