Abuse Of Cocaine

One can feel the effects of cocaine almost immediately after use, with these effects lasting only a few minutes or hours. The duration of cocaine 's effects depends upon how it is administered. The faster the drug is absorbed, the more intense the high, but also the shorter the duration. The high from snorting is relatively slow to arrive but it may last 15 to 30 minutes. In contrast, the effects from smoking are more immediate but may last only 5 to 10 minutes. “In the brain, cocaine interferes with the chemical messengers -- neurotransmitters -- that nerves use to communicate with each other. Cocaine blocks norepinephrine, serotonin, dopamine, and other neurotransmitters from being reabsorbed. The resulting

The short term physiological effects of cocaine include constricted blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. Large amounts intensify the user’s high, but may also lead to bizarre, erratic, and violent behavior. The short term effects on the brain are tremors, vertigo, muscle twitches, paranoia. Some users of cocaine report feelings of restlessness, irritability, and anxiety

The short term effects of the crack includes: higher breathing rate, elevated blood pressure, soaring heart rate, compressed blood vessels, lack of appetite, dilated pupils, extreme euphoria for both casual and heavy users. The long term effects are the following: depression, violent, fearful performances, hallucinations, bad temper, psychosis, heart attack/stroke, sterility (for both men and women), brain convulsion, respiratory malfunction and even death for heavy users! Since crack cocaine is exceedingly addictive, addicts can easily build up tolerance and become addicted in a short time by smoking it constantly. There are many ways to take crack cocaine. Users can smoke through a hand pipe or a water pipe, snort, infuse through vein, or they can combine crack with marijuana, heroin etc (University Of Maryland). While taking crack, users face plenty of risks like: coughing, respiratory bleeding, out of breath, paranoia, lung trauma and many more (“Crack cocaine facts”). Dealers shipped crack cocaine from the Bahamas and the Caribbean to Miami, where the dealers would sell it for lower incomes (“A Complete History of Crack Cocaine”). Anyone can be addicted to crack cocaine – from adults to teens. Crack cocaine is most rampant in urban regions but addicts from rural areas can also be seen. Crack is highly addictive because a user trying for the first time becomes addicted to it and he uses it many times throughout the day. A single dosage is inexpensive but a crack

For short-term use, cocaine can provide extreme happiness, enhanced sensitivity to sound and touch or mental alertness. People takes cocaine as it can provide energy on their work but a long-term use of cocaine may lead to malnourishment, irritability, restlessness, paranoia and auditory hallucination (NIDA, 2016; Roncero, C., et al., 2013). Also, cocaine abuse may have other complications such as nosebleed because of snorting, difficulties in swallowing and easily infected by HIV or hepatitis C through needle injection and the misjudgment on having unsafe sex (NIDA, 2016). On the other hand, long-term use of cocaine may lead to addiction and a stronger dosage will be taken when they have any withdrawal symptoms. For instance, symptoms of depression, fatigue and increased appetite. Nowadays, still no medicines were approved for treating the addiction on cocaine and thus the treatment of cocaine addiction is

One of the most detrimental and addictive narcotics in the world today is cocaine. Cocaine dates back as early as 3000 BC. Ancient Incas used the coca leaves to counter the effects of living in thin mountain air. Native Peruvians in the 1500’s chewed the plant strictly for religious ceremonies. Andean Indians are believed to chew the leaves of the coca plant to increase their energy for work while decreasing their hunger and pain. It wasn’t until 1859 when a German chemist Albert Niemann successfully extracted the narcotic from the coca leaf. In the 1880’s, it was freely prescribed by physicians for “maladies as exhaustion, depression, and morphine addiction and was available in many patent medicines” (“Cocaine”), until users and doctors began to realize its dangers and side effects. While it was not fully understood at the time, cocaine has many devastating and lasting effects on the user.

Cocaine’s primary effect on the brain is to produce “psychoactive and addictive effects primarily by acting on the brain’s limbic system, a set of interconnected regions that regulate pleasure and motivation. Initial, short- term effect- a buildup of the neurochemical, dopamine which gives rise to euphoria and a desire to take the drug again”(Nestler, 2005, p.4). This is normally seen in some individuals that draw in the drug like through inhaling. It gives them an instant increase in blood, and brain levels. It causes the individual to become addicted to this substance. Cocaine is thought to produce pleasure/reward like any addicted drug

It is composed of many functional groups, which explain for the different types of functions. Cocaine has an educational background both in science and in history. It has been used recreationally throughout history and made its way to the European continent and other areas after the European colonized in South America. The native people of South America used to chew on coca leaves to extract the compound and use it as a source for energy and power to complete daily tasks. There is also evidence of the natives using this coca leave for medicine. The medicine component behind cocaine dates back to centuries ago. The skeletal remains show that some people used to chew on it as they were going through a medical procedure. These people had residue left in their cheekbones, and there was a hole in their skull. This signified that the people went through a medical procedure to get treatment for brain illnesses. The ones without these holes show that it was being used recreationally. It has a rich, detailed scientific background as many people sought to uncover the pure substance. Uncovering the pure substance only lead to further advancement in medicine; Cocaine was being used as a local anesthetic. People further went on to create derivatives of cocaine, which are the more popular anesthetics used in medicine right now. Some of these anesthetics include Benzocaine and Lidocaine. These anesthetics are typically used to treat ulcers. Cocaine, today, seems to be more of a social issue due to numerous people abusing the drug and getting addicted. It is evident that there are beneficial and detrimental uses of the drug. Cocaine can cause harm when it is abused or used in the wrong way. It can lead to serious complications and consequences. However, Cocaine also has great application in the medical field. It can be used as a good way and lead to many

“There are changes in the brain caused by drug use that occur and persist, but are only unmasked after withdrawal from a drug — in this case, cocaine," senior author David Dietz explained in the press release. "Cocaine use alters the connections between certain neurons through changes in the shape of the cells."

It stimulates the central nervous system, which strongly influences the mind and body, which allows people to function far faster and efficiently while using cocaine. It also reduces the size of the frontal lobe, the part of the brain which is responsible for decision making and self control. People with larger frontal lobes are far less likely to become addicted to substances because they believe that the risks far outweigh the gains of addictive substances (Dept. of Psychiatry). The frontal cortex analyzes information and compares possible courses of actions. It allows people to skip certain things that they know are detrimental but might cause good feelings, such as drugs, to avoid their negative side effects. Cocaine impairs the frontal cortex, which makes people far less likely to avoid the negative substances in exchange for the good feelings of pleasure. When people begin to withdraw from the drug they experience many anxiety symptoms (Van Bockstaele). This is caused by the residue of the kappa receptor stimulation (Goodman). Cells are altered to change the conscious memories and desires of people into uncontrollable impulses that can be easily triggered. Triggers include seeing cocaine, seeing the tools to use cocaine, and then just seeing simple posters of cocaine (Nestler). It is one of the strongest drugs out there and thus it is one that most strongly affects the

It can cause respitory failure, stroke and heart failure. People who continue to use cocaine may show symptoms similar to schizophrenia, it can cause severe mood swings, reduce libido, weight loss and insomnia. It is estimated that 1.3 million people in the U.S. use cocaine every month (Virtual Mass Spectrometry Laboratory 2003).

Cocaine has much impact on your body. Cocaine is a stimulant that increases your body,

When cocaine is used an electrical signal in the presynaptic nerve cell release neurotransmitters across the synaptic cleft to bind to receptors on the postsynaptic cell. Once the neurotransmitters are bound to the receptors a release of a new electrical signal occurs in the postsynaptic cell. The neurotransmitters are gradually removed from the receptors and brought back into the presynaptic cell through neurotransmitter specific reuptake pumps on the lining of the presynaptic cell. Cocaine affects the levels of dopamine, serotonin and Norephedrine by blocking the reuptake pumps.This results in excess levels of the neurotransmitters to be in the synaptic cleft. These high levels of neurotransmitters continue to bind to receptors which releases more electrical signals to the postsynaptic neuron. Over time this hyperactivity of the neuron causes the postsynaptic cell to reduce the number of receptors on it. Once the hyperactivity stops in the postsynaptic cell normal cell function resumes. However with fewer receptor cells the user feels a lessened sensation of the neurotransmitters. The physiological effects of cocaine can be attributed to the chemical process it disrupts in the nerve cells. Loss of appetite, disturbed sleep patterns, nausea, anxiety, paranoia and depression are attributed to altered serotonin levels. Increased heart rate, increased blood pressure, increased body temperature, contracted

Stroke. Heart attack. Altered cardiac rhythm. These medical emergencies are common during a cocaine overdose. In addition to these immediate health consequences - prolonged cocaine use can alter the function of vital organs - which includes the possibility of permanent brain damage.

However, everything comes at a price, the short-term health effects are: constricted blood vessels, dilated pupils, nausea, raised temperature and blood pressure, faster heartbeat, tremors and muscle twitches, and restlessness. The long-term effects of cocaine depend on how it is taken. If it is snorted effects include: loss of sense of smell, nosebleeds, frequent runny nose, and problems with swallowing. Ingesting orally leads to severe bowel decay from reduced blood flow. If it is injected, the effects include higher risk of contracting HIV, hepatitis C, and other bloodborne diseases. However, those who use non-needle forms of cocaine are still at risk for STDs because cocaine affects one’s judgement so one may lead to unsafe sexual behavior. Long term effects shared by all forms of cocaine include: being malnourished due to cocaine’s appetite suppressing properties, movement disorders such as Parkinson’s, irritability, restlessness, and severe paranoia which can lead to the loss of touch with reality and cause auditory hallucinations. Along with all the previously mentioned effects, if someone becomes dependent on cocaine, withdrawal symptoms include: depression, fatigue, increased appetite, nightmares, insomnia, and slowed cognitive function. I personally know someone who has tried cocaine and here’s what they said on the matter:

The drug Cocaine alters chemical levels in the brain which can lead the user to have the ‘feel good’ factor.
