Drug abuse is part of everyday life, many of us know someone who has abused drugs at one time or another. A way to simplify a difficult moment in our life, we find a way out in a product that numbs our brain to its surroundings. People find addiction through drugs, activities, and actions that create chemical reactions within our bodies. Whether you love jumping off the Empire State Building or injecting a drug, you're looking for a high that your body enjoys. The body creates chemicals that impede our self-control. According to the CDC website, “overdose deaths have increased steadily over the past two decades and have become the leading cause of injury-related death in the United States.” (Birnbaum HG, web). Dopamine is a reward chemical in the brain that rewards us whenever we do something positive. The addiction comes from that chemical and can be created by various activities. Someone might enjoy jumping off a cliff, eating food, taking drugs, or even playing video games. Whenever your brain likes something, dopamine is released and you start to feel good.

The brain functions neuropathically, and the drugs interrupt the normal process that prevents the frontal lobe from functioning as it should. The treatment is not done properly and patients tend to repeat their habit after leaving rehab. Psychological treatment is not as effective as chemically injecting dopamine to reward the brain.
