1) What is the drug? What is the chemical name and the common ?
Nicotine is derived from the tobacco plant. Chemical name is 3-(1-methyl-2-pyrrolydinnyl)pyridine. Common forms are tobacco, cigarettes, and cigars.
2) Ways the drug is obtained (synthetic or not) Does it come from another living thing, or is it synthesized (made) in the lab?
Nicotine can be a synthetic drug however it also can be made several types of plants. It is naturally in tobacco and the nightshade family.
3) What does it do to the body that makes the user take it or abuse it? (Why do users LIKE using this drug or why can't they stop using this drug?)
the drug is a stimulant which speeds up the messages from the body to the brain. After the body gets rid of the drug,

the person feels withdrawal symptoms and to avoid the symptoms, a person would be compelled to take another one. 4) What body systems are affected by it? When a person smokes, the chemical(?) is inhaled deep into the lungs, which is then absorbed into the bloodstream that is circulating throughout the body and through the lungs.
It is quickly transported all over the body to the heart, blood vessels, nervous system and endocrine. (Circulatory, respiratory, endocrine, muscular, nervous system)
5) How much time does it need to take affect, How long does it last in the body?
Nicotine does not take long to take effect and can reach the bloodstream and brain rather quickly. This depends on how the drug was ingested, how much they ingested, and how long the person has been taking nicotine.
6) Can the body system recover from the drug, does it have any permanent effects to the body
The circulatory system can recover once it gets rid of the nicotine and it regulates the amount of fats and plaque inside the bloodstream and attached to vessel walls. (This can happen because nicotine is a stimulant which causes a flight or fight response which means that stored fats are released into the bloodstream to give the energy to run or fight. However, there is nothing to run from or to fight so there is excess fat in our bloodstream and plaque may form from all the fats and other nutrients inside the bloodstream). Also, the increased heart rate and blood pressure will return to normal soon after ingesting the
frug. The respiratory system can partially recover because there may be permanent damage to the lungs. The effects on the respiratory system are “irritation of the trachea (windpipe) and larynx (voice box) reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages impairment of the lungs’ clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage increased risk of lung infection and symptoms such as coughing and wheezing permanent damage to the air sacs of the lungs.” The nervous system can recover once it gets rid of the nicotine and The endocrine system will recover once it regulates the amount of adrenaline released by the adrenal glands. Nicotine can control the amount of adrenaline released because it binds to a part of the brain that controls the flow of adrenaline.
Nicotine is a highly toxic substance (LD40) which can affect the brain, central and autonomic nervous system
Many of the problems associated with early sobriety do not stem directly from psychoactive substances. Instead they are associated with physical and psychological changes that occur after the substances have left the body. When a person regularly uses psychoactive drugs, the brain undergoes physical changes to cope with the presence of drugs in the body. When the drugs are removed from the body, the brain craves the drugs that it has become accustomed to and as the brain attempts to rebalance itself without the presence of psychoactive drugs the person often experiences feelings of confusion, pain, and discomfort. The symptoms that are experienced immediately after stopping drug use are called acute withdrawal.
Surprisingly, some people actually take this drug on purpose for the euphoric high that it produces. This practice is also extremely dangerous because in addition to the side effects, the drug can be addictive. This means that the longer you use it, you need to use more and more to reach the same level of “high” and if you stop taking it, you go through withdrawal.
Cigarette addiction is responsible for over four million deaths every year. The question most people ask is why don’t people just put down their cigarettes? Well, the answer to that often asked question is nicotine. Nicotine is a neurotransmitter that targets certain receptors in the brain. It is a chemical messenger that induces feelings of pleasure. When someone takes a hit off of a cigarette, they ingest the harmful chemicals that can cause cancer and other serious health threats. They only inhale these chemicals to get one thing and one thing only, nicotine.
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.
Unfortunately as the drug raises dopamine to unnaturally high levels the addict finds that the only way to achieve a balance is to continue to use the drug. This changes the hierarchy of important survival needs that release dopamine such as food, water, sex, the mid brain is literally telling the addict they need the drug to survive more so than anything else.
In the world today, Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4,000 chemicals found in the smoke of tobacco products such as cigarettes, cigars, and pipes. This addictive drug is the primary component in tobacco that acts on the brain.
Drugs come from a wide variety of different places. Many are from plants but some, like heroin have to be chemically modified from morphine. Places that drugs come from can be very common. Caffeine, some people may not know but is considered a drug, comes from cocoa beans, while nicotine comes from tobacco. Mostly, these drugs have to be grown in their natural habitat, however they can be grown in an artificial setting. Many times because dealing drugs is illegal dealers will set up this setting in the basement of their house or some other discreet place (Vicc Drug Guide).
The altered states of consciousness produced by drugs presents an all-to-common phenomenon in today’s society. Whether the desired sensation comes in the form of energy, a means of relaxation, or pain reduction, many people go to great lengths and present their bodies to threatening conditions in order to achieve this euphoric “high.” Unfortunately, the use of these drugs very often comes with dangerous side effects that users must learn to manage with for the rest of their life. According to neuroscientists, our entire conscious existence bases itself off of the lighting-fast reactions occurring in our nervous system (Nichols, 2012). Therefore, changing these neurological reactions can permanently effect our conscious being (Blatter, 2012). The physical and neurological effects from the use and abuse of stimulants, sedatives, hallucinogens, organic solvents, and athletic performance enhancing drugs will be discussed in order to better comprehend why certain individuals expose themselves to such dangerous materials with seemingly no regard to the permanent consequences associated with such actions.
The brain and other organs are then exposed to it once contaminated blood flows through the body. If the substance is consumed through food or drink, it has been proven that the effects of the drug take longer to show effect on the body. The chemical effects cell receptors within the brain. These receptors would normally react to chemicals that might resemble THC, and regulate normal activity and development. Concentrated areas where these receptors are located are thrown into overdrive, and can cause sensations that users would consider a “high”. Some of these effects are compromised memory, difficulty controlling body movement, changes in senses, altered moods, impaired ability to think and solve problems, and a skewed sense of
Tobacco, as we use it, is a preparation of the nicotine-rich leaves of the tobacco plant, which are cured by a process of drying and fermentation and later used for smoking, chewing or as snuff. It is the primary ingredient in cigarettes, gutkha and bidis. The botanical name of the tobacco plant is nicotiana tobaccum.
The body adjusts to the Nicotine and craves it when it’s missed. But the main addiction is mental. The proof is found among Shabbat observers who can abstain from smoking the whole Shabbat. So it mainly depends on the habits a person has.
The use of drugs is a controversial topic in society today. In general, addicts show a direct link between taking drugs and suffering from their effects. People abuse drugs for a wide variety of reasons. In most cases, the use of drugs will serve a type of purpose or will give some kind of reward. These reasons for use will differ with different kinds of drugs. Various reasons for using the substance can be pain relief, depression, anxiety and weariness, acceptance into a peer group, religion, and much more. Although reasons for using may vary for each individual, it is known by all that consequences of the abuse do exist. It is only further down the line when the effects of using can be seen.
Smoking cigarettes is a very deadly addiction that, unfortunately, affects 42.1 million adults in the United States and 6.4 million children. The reason why so many people get addicted to cigarettes is because of nicotine. Medicinenet.com says that nicotine is “made by the tobacco plant or produced synthetically”. Nicotine has powerful pharmacologic effects (including increased heart rate, heart stroke volume, and oxygen consumption by the heart muscle), as well as powerful psychodynamic effects (such as euphoria, increased alertness, and a sense of relaxation). Nicotine is also powerfully addictive.”
There are many causes which make people smoke, however it can be divided into two main causes: physical and psychological. First cause which is physical concerns the human body’s needs. Nicotine contained in cigarette is an addictive substance. It is the chemical which causes addiction. Nicotine reduces tension in the muscles and allows smokers to relax so they feel that they can relieve stress by smoking. Nicotine can also have a calming effect on people who are anxious and worried. This is why it can bring a feeling of tranquility and help smokers to cope with stress. Thus, people smoke when they are depressed, lonely or bored. Nicotine is absorbed by the smoker’s lung and intestines. Very quickly, nicotine can stimulate brain and certain types of nerves so heart rate and blood pressure go up; respiration increases. A little nicotine makes smokers feel more energy and improve concentration. As a consequence, these physical effects created by smoking play an important role in making people feel the need to smoke.
