Drugs Affecting The Human Body
Brains contain many different neurotransmitters that affect humans differently. The brain uses these neurotransmitters to create different feelings and emotions within humans. A deficiency in these neurotransmitter causes problems with nerve impulses that can lead to depression. There are many drugs that can intentionally change these normal chemical processes in our brain to maintain the feeling of happiness; however, these drugs are extremely dangerous to the human body and are unhealthy for humans. `The brain is a complex organ that has a complex, but quick process of delivering the neurotransmitters to the receptors. Neurons communicate with each other by sending electrical signals, nerve impulses, through tube like structures called axons.

Serotonin can increase self-esteem and confidence in a person. However, low serotonin levels correspond with depression and violent actions. High levels of serotonin can create a feeling of accomplishment in a person while low levels can create depression. Similar to dopamine, there are addictive, dangerous drugs that can alter the serotonin's levels in the brain. A drug that is capable of altering the serotonin levels is ecstasy. Serotonin is usually not released all at once; however, drugs like ecstasy cause serotonin to release all at once which creates strong feeling of accomplishment and an increase in self-esteem. Similar to methamphetamine and cocaine's effects on dopamine levels, anti-depressants help to keep serotonin in the synaptic gap for a longer period of time. However, anti-depressants can be legally prescribed by a doctor while some addictive drugs can be illegal. One of these anti-depressant is known as Serotonin-Specific Reuptake Inhibitors (SSRIs). Although these anti-depressants may be legally prescribed by a doctor, they can still be dangerous if they are consumed in large quantities. Both addictive drugs and drugs from a doctor can increase serotonin levels and can control the amount of serotonin in the brain, but both drugs can be harmful. This is because these drugs can cause a change in the brain chemistry of a person which causes the person to crave the drug. Once a person craves a drug, they
