Recommended: Causes and consequences of drug use
When thinking about how drugs affect people, friends and family often focus on the visible. They see the changes in personality, financial problems, and deteriorating health. The thing they often don’t ask is how do drugs affect the brain. It’s just as important because the brain plays such an important role in addiction.
How Do Drugs Affect the Brain?
It’s important to realize that different kinds of drugs affect the brain differently.
Alcohol, for example, reduces your ability to form memories. Heavy, long-term drinking can actually reduce your brain’s size and damage your ability to think. Cocaine, on the other hand, activates the pleasure center in your brain. Long-term use can cause paranoia and hallucinations.
The thing all drugs

have in common is that they alter the amount of certain chemicals in the brain called neurotransmitters. Neurotransmitters There are several important neurotransmitters. The ones drugs most frequently affect include: • Dopamine • Serotonin • GABA • Norepinephrine Dopamine creates a sense of pleasure, while serotonin affects your mood.
GABA is a natural calming agent. Norepinephrine amps you up to take action.
It’s important to remember that your body makes these chemicals and for good reasons. In normal doses, they help keep you mentally and emotionally stable. They also help your brain prepare for or appreciate an activity.
For example, the smell of a steak on the grill triggers a small dopamine release in the brain of someone who likes steak. The smell becomes a source of pleasure.
What drugs typically do is trick your brain into making huge amounts of these chemicals. Cocaine does this by preventing the brain from turning off the flow of dopamine. As the dopamine builds up, you get euphoric and energized.
Most drugs also cause brain damage. The brain simply isn’t designed for the extremes that drugs create.
Treating Drug Dependence and Addiction
How do drugs affect the brain is an important question. Just as important is the question, what’s the best way to treat drug dependence and addiction?
For most kinds of dependence and addiction, the best option is a chemical dependence treatment center. Treatment centers offer medical staff and experts in addiction treatments. Some centers offer both traditional therapies and holistic treatments, such
as: • Individual talk therapy • Group meetings • Family therapy • Yoga • Meditation This combination of traditional and holistic treatments helps address the mental and emotional side of addiction, as well as the physical and spiritual. Crest View Recovery Center Crest View Recovery Center offer rehab programs for men and women. They use both traditional and holistic treatments as part of their reality therapy approach.

According to the Centers for Disease Control, methamphetamine, or meth as it is often referred to, is considered the fastest-growing illicit drug in the United States. The consequences of usage are detrimental to families and employers, not to mention the increasing law enforcement burden of having to find and disband labs making it illegally. (CDC, 2005) Aside from the far-reaching implications of methamphetamine use on these entities, this paper explores the effect methamphetamine has on the structure and function of the human brain.
Cocaine (C17H21NO4) comes from the leaf of an Erythroxylon coca bush. It is a drug that effects the central nervous system. It causes feelings of euphoria, pleasure, increased energy and alertness. People under the influence of cocaine often do not feel the need for food or sleep. They also feel energetic and may talk a lot. However, depending on factors such as environment, dosage, and the manner in which the drug is taken, cocaine can have adverse effects such as violent, erratic behavior, dizziness, paranoia, insomnia, convulsions, and heart failure to name a few. Long- term effects of cocaine include, but are not limited to strokes, heart attacks, seizures, loss of memory, and decrease in learning capability (1).
In the brainstem, the most primitive part of the brain, lie clusters of serotonin neurons. The nerve fiber terminals of the serotonergic neurons extend all throughout the central nervous system from the cerebral cortex to the spinal cord. This neurotransmitter is responsible for controlling fundamental physiological aspects of the body. In the central nervous system (CNS), serotonin has widespread and often profound implications, including a role in sleep, appetite, memory, learning, temperature regulation, mood, sexual behavior, cardiovascular function, muscle contraction, and endocrine regulation. Not only does this bioamine control physiological aspects of the body, but it also has an involvement in behaviors like eating, sleeping and aggression. Serotonin has been noted to produce an inhibitory effect on the nervous system that calms, soothes and generates feelings of general contentment and satiation.

All drugs have a negative effect on the nervous system, but few can match the dramatic impact of cocaine. Cocaine is one of the most potent, addictive, and unpredictable recreational drugs, and thus can cause the most profound and irreversible damage to the nervous system. The high risk associated with cocaine remains the same regardless of whether the drug is snorted, smoked, or injected into the user¡¯s bloodstream. In addition to the intense damage cocaine can cause to the liver, intestines, heart, and lungs, even casual use of the drug will impair the brain and cause serious damage to the central nervous system. Although cocaine use affects many components of the body, including vision and appetite, the most significant damage cause by cocaine takes place in the brain and central nervous system.
As with any other disease, drug addiction causes stress and breaks down the body immune system. Not only does drug addiction break the body immunes system down but it also decreases brain function. In the book addiction treatment a strengths perspective, the authors Wormer and Davis stated, “Other remedies directed toward the physical side of drug use are more natural, holistic approaches. These include various herbal remedies, acupuncture, massage, hypnosis, and biofeedback.” (Pg 204) In my opinion, the holistic approach can be very practical for treating the disease of addiction because it will help people gain the proper balance for those who suffer from addiction.
The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
Also, involved in chemistry are dopamine and norepinephrine, chemical cousins of amphetamines. Dopamine, a neurochemical released by PEA, makes us feel good.(1) A recent study done at Emory University shows that female voles (small rodents) choose their mates in response to dopamine being released in their brains. When injected with dopamine in a male vole's presence, the female will pick him out of a crowd later.
There are many biological factors that are involved with the addicted brain. "The addicted brain is distinctly different from the nonaddicted brain, as manifested by changes in brain metabolic activity, receptor availability, gene expression, and responsiveness to environmental cues." (2) In the brain, there are many changes that take place when drugs enter a person's blood stream. The pathway in the brain that the drugs take is first to the ventral tegmentum to the nucleus accumbens, and the drugs also go to the limbic system and the orbitofrontal cortex, which is called the mesolimbic reward system. The activation of this reward system seems to be the common element in what hooks drug users on drugs (2).

Drugs affect your brain and in turn can alter your moods and behavior. Drugs are chemicals that tap into our brain’s communication system and disrupt the way nerve cells receive, send and process information. Drugs interfere with the exchange of information in the brain producing changes that promote repeated drug use. Drugs can imitate the brain’s natural chemical messengers, or they over stimulate the reward circuit of our brain.

Cocaine can be snorted, smoked, injected or even chewed; it can be consumed in any way as long as it ends up in the blood stream. It is a stimulant drug, meaning the messages travelling between the brain and body speed up. Cocaine affects the production, uptake and breaking down of three chemicals that naturally take place in the brain. These are: Dopamine, Serotonin and Norepinephrine. ...
Many people that have smoked marijuana also try other drugs to get another type of high. Cocaine is a powerful stimulant that effects the brain directly. This powerful drug takes effect in very small doses by making a person feel more alert or energetic. Though people may think the drug helps them perform tasks faster with fewer complications, it also carries a list of effects. Some include constricted blood vessels, dilated pupils, high temperature, high heart rate, and bizarre behavior. Some...
Abuse can cause countless medical problems to the body. A person who is addicted will continue to stimulate themselves regardless if they are aware of the negative chain reactions. Once addicted, it becomes difficult to stop due to how the body has become dependent. Health will be harmed the more a stimulant is used. Health effects include: cardiovascular disease, strokes, cancer, HIV/AIDS, hepatitis, lung disease, mental disease, birth defects. Mental health is what keeps a person in the right mind to make better decisions and have better control in life. Drugs have the ability to change mood and behavior. If drugs have affected the brain already, the desire increases which changes mental health. Some may not realize that they have been affected their health negatively. “A person who abuses drugs may not realize they have a problem until pronounced effects of drug abuse are seen, often physically. While drug abuse effects on the body vary depending on the drug used, all drug abuse negatively impacts one 's health (Addictions Community). Since drugs create many health issues, treatment is not a simple task. Treatments are hard to obtain and addictions often go
