Illegal Drugs affect everybody from young kids to grown up adults. Sometimes we see it ruin families and lives of people we care for. This essay is going to go over why drugs should stay illegal and ways we can help people stay off the drugs. First of all let’s talk about some of the drugs and what they are about. The first drug that is going to be talk about is Marijuana. They are trying to legalize that in every state for medical use. There are people who don’t want to see that happen. They want people to realize the effects it has one people. Some of the effects it has on people are “within a few minutes after inhaling marijuana smoke, an individual's heart begins beating more rapidly, the bronchial passages relax and become enlarged, and blood vessels in the eyes expand, making the eyes look red. The heart rate, normally 70 to 80 beats per minute, may increase by 20 to 50 beats per minute or, in some cases, even double. This effect can be greater if other drugs are taken with marijuana.” (Why illegal drugs should stay illegal). Well that could cause a person to have heartache, which is not good. It also gives you a natural high that makes you......

...presentation about drugs in common and special drugs Drugs in common: What are drugs ? A drug is any chemical you take that affects the way your body works. Alcohol, caffeine, aspirin and nicotine are all drugs. A drug must be able to pass from your body into your brain. Once inside your brain, drugs can change the messages your brain cells are sending to each other, and to the rest of your body. They do this by interfering with your brain's own chemical signals: neurotransmitters that transfer signals across synapses. Drugs lead primarily to a intoxication or emergence of a dependency syndrome. They change the awareness and the perception of the consumer during their impact and beyond. They affect three primal parts of the brain: • The brain stem which is in charge of all of the functions our body needs to stay alive • The limbic system links together a bunch of brain structures that control our emotional responses. • The cerebral cortex is the mushroom-like outer part of the brain. In humans, it is so big that it makes up about three-fourths of the entire brain. It’s divided into four areas, called lobes, which control specific functions. Some areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, known as the frontal cortex or forebrain, is the thinking center. It powers our ability to think, plan, solve problems, and make decisions. How do they proceed in our brain ? Drugs......

...Drug Trafficking Global Issues in Context Online Collection, 2014. [pic] [pic] Drug trafficking refers to the international black market trade of illegal drugs. While some drugs are produced and sold locally, the cultivation and manufacture of some illicit drugs occurs in only a few locations around the world. Most of the world's supply of cocaine comes from Central and South America and most opiates are cultivated in Central, Southeast, and Southwest Asia. A chain of drug cartels ships drugs around the world in order to get the drugs from the point of production to the user on the street. The United Nations Office on Drugs and Crime (UNODC) in its “World Drug Report 2008” estimates that 208 million people worldwide use drugs annually on at least one occasion. The vast majority of global drug uses involved some form of cannabis. UNODC estimates that 165 million people have used cannabis in the last year. Amphetamine use comes in second with about 25 million users per year. According to United Nations (UN) estimates, the drug trade is a $400 billion per year industry. Drug trafficking traces its roots back to eighteenth-century China. By the late seventeenth century, opium addiction had become a major problem on the Chinese coast, where European traders imported opium from other parts of Asia. In 1729, the Chinese emperor banned the importation of opium into China. As the supply of opium decreased, the price of opium increased and drug smuggling increased. By the end......

Feeling confused about whether or not taking drugs is the right choice for you is not unusual. Drugs can appear initially to have positive effects – lifting your mood, relaxing you or even giving you more energy. However, they can also have negative impacts on your mental and physical health, your relationships, and your life in general. When you are making your decision, consider the following points: Do you know what you are really taking? For example, most ecstasy is not actually MDMA. What do you know about the person who's selling you the drug? Are you taking anything else (alcohol, illicit drugs, over the counter or prescribed medication) that might interact with the drug? How likely is it that you will have a positive experience? How do you know that the next experience is also going to be a positive one? Do you know that you will be able to control your drug usage and that it will be safe? Can you really afford it? Do you know the safest method of use? Are you in the right environment – is there someone to help if something goes wrong? Do you know what the......

...Janaki Patel Club Drugs Club drugs are becoming more abundant in society nowadays and readily available almost everywhere you go whether it is on the streets of a hustling bustling city like New York, a suburb like Princeton, or schools like Harvard. Not just club drugs, but all kinds of drugs are readily available, but right now club drugs are on the rise statistically. A recent survey shows approximately “37.1% of 12th graders, 24.8% of 10th graders, and 12% of 8th graders reported that MDMA was "fairly easy" or "very easy" to obtain” (Drug Free Website). Clearly it is evident that these club drugs are easy to obtain by the average American teenager. So what are club drugs? Club drugs are drugs used at parties, raves, clubs, and discos to maximize their clubbing experience. These drugs help acquire the euphoric feeling by releasing a chemical in the brain called serotonin which makes you feel good. The most common type of club drugs are ecstasy, GHB, Rohypnol, and LSD. In addition to these drugs, there are many more part of the category of club drugs. However, sexual predators can misuse a couple of these drugs as the date rape drug.

...As one prescription drug abuser in his early 20’s explained: Once people (pill brokers) know you take them prescription opioids, they’ll start calling you. “Oh, it’s this time of the month.” Then they wait for that person to get their script. They know exactly in their head what day the script’s getting ready to come so they got the patterns down. Pill brokers and dealers reported congregating in open air drug markets typically strip mall and pharmacy parking lots, and outside methadone clinics to buy, sell, and trade prescription drugs. These markets were reported to involve a variety of transactions, including the purchase of prescription drugs for cash, as well as trades for crack and heroin. Pill brokers also reported the purchase of used fentanyl patches from nurses who have stolen them from pain patients or from disposal containers in hospitals. Some individuals frequenting the drug markets also barter their oxycodone for other opioids or benzodiazepines, typically alprazolam. Doctor Shopping focus group participants indicated that even in a small state like Delaware, doctor shopping appeared to be fairly easy. The vast majority of abusers reported obtaining medications through doctor shopping, and most reported frequenting at least four physicians in order to obtain sufficient amounts of their desired medications. Occasionally clinics and hospital emergency rooms were reported as locations for doctor shopping as well. A heavy user stated: Another focus group member...

...Drugs and the Brian People use drugs every second, every minute of every day they are just a devastating part of our lives, but it’s your choice to use them or not. The first drug every recorded was ethanol [alcohol] around 4000 b.c. Over a hundred years ago drugs were used for “special’ occasions (Bishop). Nowadays kids use them like they’re candy and by their 45th birthday they’re almost dead. Drug abuse is one of the leading causes of cancer, death and mental illness. Drug abuse is the second largest form of abuse in teens ages 13-18 (alcohol is number one). The Effects of Drugs Drugs can quickly take over your body, like somebody is controlling you from the inside making you 35% more likely to steal, fight, and getting a D.U.I [driving under influence] (“Marijuana Myths and Facts”). Next they hijack your “reward” circuit and make you overdose on dopamine [gives you good feelings] this will happen in your limbic system (is the set of brain structures that forms the inner border of the cortex). Certain drugs will interfere with your nervous system and change the way you send receive and process information (“Teen Drugs”). THC [delta-9-tetrahyfrocannbinol] is a very harmful substance found in many drugs it rapidly passes though the lungs into the bloodstream and leads to your brain. This will have many short and long term effects, for example memory loss, hard time thinking/concentrating and problem solving. Short term effects like time/perception loss or......

...Drugs Kendall Beard COM/172 May 6, 2015 Brian Townsley In my experience, for decades, many people have debated over the use of marijuana and whether it is good or bad for you. Many scientists have conducted their research on the usefulness of marijuana in the everyday life of people and most have only come back with negative results concerning the plant/drug. In this paper, I hope to prove that smoking marijuana does not cause the same amount of problems that smoking cigarettes might cause. In this paper, there will be few topics touched on concerning marijuana. There are ample cases of people using drugs because of their curiosity, individual freedom and choice, cultural characteristics, or relaxation activities and the substitute for modern medicine. Modern hemp and cannabis are distinctive assortments of the same species, Cannabis sativa. Weed generally contains 3 to 15 percent of the psychoactive fixing delta-9-tetrahydrocannabinol (THC) on a dry-weight premise, while mechanical hemp contains 1 percent. Be that as it may, the two mixtures are unclear by appearance. In the United States, Cannabis sativa is delegated a Timetable I controlled substance, paying little respect to its opiate content, under the Controlled Substances Go about as changed. Since 1990, mixtures containing under 0.3 percent THC have been sanctioned in Incredible Austria, England, Switzerland, and Germany. Canada and Australia authorized hemp generation in 1998. In different nations, for......

...Mexico’s Drug War Drug trafficking has become an increasingly growing problem in the world today. Illegal drug trade is a worldwide black market consisting of production, distribution, packaging, and sale of illegal substances. Although today’s "War on Drugs" is a modern phenomenon, drug problems have been a common problem throughout history. The market for illegal drugs is massive, when we consider the estimated global drug trade value is worth $321 billion (Vulliamy). The most drug trafficking happens on the border between Mexico and the United States. Former Mexican President Felipe Calderon said, “Our neighbor is the largest consumer of drugs in the world. And everybody wants to sell him drugs through our door and our window” (Catholic Online). Mexico is the main foreign supplier of marijuana and a major supplier of methamphetamine to the United States. Mexico is responsible for 90% of drugs that comes from the southern border of the United States. Mexico has been a producer and distributer of illegal drugs for generations; the country now finds itself in a battle with powerful and well-financed drug cartels. The corruption in the Mexico, the trafficking of weapons and the violence has made it possible for cartels to keep operating. Since 2006, when president Calderon declared the war on drug cartels, violence in Mexico has increased dramatically. The country has certainly seen a big rise in drug violence, with cartels fighting for control of major shipment routes.......

...attractive for drug dealers and users. In New York City there isn’t much evidence proving that the drug market have been totally eliminated. The drug markets have been remodeled due to aggressive police tactics in the neighborhoods. In 1990s, Mayor Giuliani showed a report of drug arrests at an all-time high and mainly because of arrest of marijuana smokers. In 1973 the Knapp Commission report revealed an huge corruption in the police department. The city created “Hands off” policy for police officers towards drug the market. This policy was created to enforce to avoid corruption and bribery. Since the 1970s and 1980s, the drug market has come a long way. People were taking them into abounded large spaces but as time pas on people still continued to obtained drugs like heroin, cocaine and marijuana with little difficulty. In the 1980s, the police began a steady assault on public drug dealing and other misbehavior. During that time, employers refused to hire colored people because of racial profiling. The owners were scared because they got arrested often or searched often. Between 1988-1993 the city created tactical narcotics teams to disrupt the drug markets and slow them down. Distributors closed on every Tuesday or Thursday to avoid ‘ TNT’ working days because they were simply scared. The Police Department has proved to be good at containing and controlling public drug markets In New York City. The public drug market has almost eliminated but as police adjust to drug......

...DRUGS Raymarr Shivers COM/220 April 8,2012 Jennifer Gaylor Introduction Dependency on drugs is considered by many as different in kind and is a chronic illness. Some people think that a drug pusher is just like committing murder. Drugs have been with us since the beginning of time. Depending on different eras and cultures drugs are used differently and with agriculture large quantities of drugs are able to be produced. You don’t have to be a rocket scientist to know that the drug epidemic has destroyed many dreams and lives of people of all ages and races. Just about anyone can become an addict when trying out a drug. Most people already know that pain medication is prescribed and available easy and too much and in turn this is creating addicts. In the year of 2010 pharmacies dispensed something like 42 tons of hydrocodone and 69 tons of oxycodone. That’s enough drugs to give each human being in the United States of America 24 Vicodins and 40 Percocet’s. Prescription drugs are exceeding all drugs in levels of abuse. The rates are staggering with deadly results all......
