An addiction is a chemical brain disorder causing people to repeatedly to use a drug, alcohol or it may be a certain behavior. An addict is often in denial to his loss of control, so he keeps on taking the drug without controlling how much he takes.
The use of drug increases the chemical dopamine in the brain and when the dopamine increase it causes the person to feel that he is pleasured and satisfied. This dopamine surge causes the experience of “getting high”.
When the brain’s dopamine falls back down to below the “normal” level the person who is taking the drugs feels down or sad and this is because the dopamine increase goes away. These dysphonic feelings of emptiness lead to lack of ability to experience pleasure without the use of the drug. The person who is taking the drugs will remember the feeling of getting high and over a certain period of time the brain will imprint a memory that the only way to make the brain feel normal again is to use the drug.
People who are addicted refused the fact of that they can get curried by their self’s so they need some people to be beside them to make them happy and satisfied but still with helping them to stop taking their usual drugs they have to move on with a good medical process with which they will try to take less drug each time they think of it. This process helps the brain to forget what they used to take and the time to forget the drugs depends on the person himself.
