The Happiness Myth: Drugs, by Jennifer Hecht, discusses whether or not drugs really are as bad as we believe. Many only see one side, if we are taught they are bad from the geico, it makes one is hesitant. While many chose not to do drugs in their lifetime, others are ashamed to admit they have. People have always used happiness drugs, drugs that are considered illegal today, were once used them often as we use “caffeine and Prozac. Though, today, often we disguise our own legal drugs as antidepressants, numbing agents, soporifics, or stimulants, which says a lot about the drugs society deems as okay.…
The Happiness Myth: Drugs, by Jennifer Hecht discusses the misceptions about drugs in society. Throughout history there have always been happiness drugs, though our public for the most part has been morally against them. Today, legal happiness drugs are often labeled things such as antidepressants, numbing agents, soporifics, or stimulants, which tells one a lot about what society thinks about them. On the other hand, the drugs considered illegal today were, at various times, once used as much as we use caffeine today. Which is odd since some of the drugs in markets are a lot stronger than they used to be.…
Stimulants can be used to speed up the central nervous system making a person fell more alert and aware of their surroundings. Depressants are the opposites and reduce the activity of the nervous system and produce a feeling of calm and/or “taking the edge off”. Hallucinogenics can be used to make an individual have hallucinations and have distortions in space and time. The use of drugs can cause the neurotransmitters to stop the production of certain chemicals need for healthy brain function. The blockage of second messengers, which are the chemical and electrical process which that occur in the receiving neuron, make the user need to take more of the drug in order to try to reproduce the affect on the brain. Some of the signs of use can be physical such as: rapid weight gain or loss, random eye movement, enlarged pupils, uncontrolled muscle movement, and redness of eyes. Changes and mood and behavior doing things that are out of the norm. Also great shifts in emotional stability from being very excited and happy to being depressed and suicidal.…
Drugs affect many areas of a person’s body, the central nervous system (CNS) is effected “causing mental, emotional and physical changes” (Inaba & Cohen, 2011). Pharmacokinetics describes this process by which a drug is “absorbed, distributed, metabolized, eliminated, and excreted by the body” (Inaba & Cohen, 2011). The…
Using drugs puts an excess amount of neurotransmitters in the body. When there is an overflow the brain stops making it naturally and when the drug wears off it takes time for the brain to star making the chemical once again on its own system. Some neurotransmitters are dopamine, serotonin, Acetylcholine, Norepinephrine, Gamm-amniobutyric acid, Endorphins. Endorphins are natural opiates.…
The use of substances can alter the person’s state of consciousness in many ways. The depressants, stimulants, and hallucinogens affect the level of consciousness in different ways due to their specific alterations in the level of brain chemistry in brain cells. When the substances taken breach the blood/brain barrier and reach the brain, they cause alteration in the normal levels and activities of neurotransmitters that include dopamine, endorphins, and serotonin. Any alteration in the level and functioning of neurotransmitters can cause changes in the body chemistries that in turn can cause changes in the normal functioning of the body.…
There are several methods of drug administration. They are: oral which is by mouth, its effect is slower and less efficient because they must be absorbed in the small intestine and then, depending on their molecular structures, are broken down or activated in the liver before being transported to the correct area of action (GCU, 2012). Another route is sublingual or buccal. These methods rely on the capillaries under the tongue or in the cheek for quick absorption. Medications such as nitroglycerin are given this way (GCU, 2012). A third method is topical. Medications given topically are applied to the skin and absorbed as they diffuse through the epidermis (GCU, 2012). A forth way is rectal. Medications may also be absorbed by the capillaries in the rectum. This is a useful route in patients who cannot take medications by mouth due to nausea, vomiting, or extreme disease of the mouth (GCU, 2012). A final way would be parenteral. This method involves administering medication intravenously, intradermal, subcutaneously, intramuscularly, and intrathecally (GCU, 2012). The best and most preferred route to give medication is orally. The…
There are many different ways to administer drugs. Some are through injection or inhalation, orally or through mucous members. The way are drug is administered affects the speed with which the drug acts and the duration of the effects of the drug. While intravenous…
The brain is the control station of the body. It is in control of everything you do, it even is hard at work while you sleep. Just like any other control or command center, the many parts that make up the brain must work together as a team. When drugs come into the brain, they interrupt the work and change how the brain then performs its job. These alterations can lead to compulsive drug use. Physical changes within the brain are linked to chronic substance abuse having a major impact on the brains functioning and emotional disarrays. Drugs are chemicals, which access the brains communication system and interfere with the method nerve cells send, receive and process information. “Some drugs can change the brain in ways that last long after the person has stopped taking drugs, maybe even permanently. This is more likely when a drug is taken repeatedly” (NIDA, 2011,para 6). Some drugs can copycat a natural neurotransmitter sending abnormal messages through the brain. They can also causes nerve cells to discharge excessive amounts which can eventually cause confusion on the…
Drug misuse causes significant changes to our neurotransmitter levels in the brain, and specifically levels of dopamine and serotonin. As these chemicals are both involved in the brain reward ‘circuits’ (e.g. the mesolimbic pathway) drugs produce feeling of ‘euphoria’. Drugs can affect Elizabeth’s brain in two ways, as a depressant or a stimulant to normal activity and as a result Elizabeth’s mood and behaviour is affected.…
Psychoactive drugs, also known as psychotropic drugs, have been used since the prehistoric times. Over 8,000 years ago chewing Coca leaves was popular, and psychoactive drugs were mainly based from plants. They are chemicals that act mainly on the Central Nervous System. It affects brain functions and alters your mood, thoughts, consciousness, cognition, and behavior. Some are mild and some are very dangerously addictive. The main reason we consume these drugs in our everyday life is for pleasure, and that is why they are abused. They could also be used for spiritual reasons, or therapeutic like medication. The more you use these drugs the easier you become addicted, and reliant of it.…
