Nicotine is a dangerous drug that is classified as a stimulant. That means it stimulates or speeds up one or more of the body’s systems. While this may sound like something beneficial, it does not make you faster or stronger. Instead, it puts more stress on your body than is healthy for it. Let’s look at exactly how it affects your body and what it is speeding up.
Although, quitting is not easy, but it’s very much possible. Hundreds of thousands of smokers have done it and, if an addict, you can do it too. The good news according to CDC’s fact sheet is that today, there are more ex-smokers than current smokers.
What is Nicotine Addiction?
Nicotine is usually a colorless or in some cases yellowish liquid. Small doses of nicotine are used as a stimulant, mostly in tobacco and pesticides, however, higher doses can be toxic and can interfere with the normal functioning of autonomic nerve and skeletal muscle cells.
Nicotine addiction is dependence on the drug nicotine, however, when we say nicotine addiction, we usually refer to the addiction to tobacco products that contain nicotine. Nicotine possesses mood-altering capabilities which give the user a temporary high. This high is extremely pleasing and makes the user want to use it more and more. Put simply, once you use it for long enough, you can’t stop using it. And those who try to quit, have unpleasant withdrawal symptoms which momentarily go away when they get the fix in the form of a nicotine dose.
Why is Nicotine Addictive?
According to National Institute of Drug Abuse, nicotine gets its addictive nature by activating a reward pathway in brain circuitry. The chemical that makes you crave for nicotine is called neurotransmitter dopamine, and nicotine increases its levels in reward circuits. Long-term users experience changes in their brain induced by nicotine, that lead to addiction.
That’s the chemical reasoning behind nicotine addiction, now let’s talk in a layman’s terms.
How addictive a drug can be, depends on many factors, mainly on how it enters your body. The fastest way for a drug to have its impact is by smoking or vaping it, and that’s why smokers get hooked to tobacco big time. When you use nicotine, it takes about ten seconds to reach your brain after entering your body, as it’s instantly absorbed by your bloodstream and transported to all the organs of your body . When nicotine reaches the brain, it makes the brain release adrenaline, that gives the user a feeling of high. This feeling is extremely pleasurable but doesn’t last long. After a little while, the user feels tired and down, wanting the high again.
This craving forces the user to keep taking nicotine, however, the human body is naturally tolerant to nicotine. As you continue to take nicotine for a while, your body starts to require higher amounts of nicotine to get the same high. This repeated cycle of nicotine cravings leads to addiction, which is very hard to break. Below are the most common triggers relapse triggers, familiar to every smoker:
You have to keep taking nicotine, even when you want to quit. The amount and chemistry of hormones released by your body change when you start taking nicotine. But when you stop, it has to readjust, which is very hard for it, and causes hormone misbalance. The end result is that your body is in a continuous state of adjusting the hormones after your abstinence. This state of the body is commonly known as withdrawal symptoms, which can be very hard to cope with.
Depending on their body, current state of mind, and circumstances, breaking addiction can be harder for some people than others. Several researches show that teenagers are more sensitive to nicotine and get addicted more easily. According to CDC, 90% of cigarette smokers try their first smoke by age 18, and 99% by age 26.
Nicotine Addiction vs Other Addictions
Some experts believe heroin and crack cocaine are the two most addictive drugs, with nicotine at the third spot, however, most agree that nicotine is the hardest to kick. Taking a look at the ratings of different drugs published in New York Times, on Aug 2, 1994 by two highly regarded experts reveals that nicotine tops the charts when it comes to dependence, and also is the highest ranked overall drug addiction:
Rating by Dr. Jack E. Henningfield of the National Institute on Drug Abuse
(1 = Most serious 6 = Least serious)
Rating by Dr. Neal L. Benowitz of the University of California at San Francisco
(1 = Most serious 6 = Least serious)
No matter what substance you consider, there are some serious users and then there are some infrequent, amateur users. To understand how overpowering a substance can be, we can compare the percentage of people who, after having used a substance, can still contain themselves to occasional use. In his book About Addictions: Notes from Psychology, Neuroscience, and NLP, the famous author Richard Gray mentions large government surveys that show how many addicts of different substances are regular users and how many are occasional users.
|Substance||% Regular Users||% Occasional Users|
|Tobacco cigarettes (nicotine)||90||10|
Although there will always be a difference of opinion when it comes to the most addictive substance, however, it’s a fact that nicotine is one of the top three, if not the top most addictive substance.
Is Nicotine a Stimulant?
Your heart is one of the most important parts of the body to be affected by the stimulant nicotine. Your heart rate can increase as part of a craving or during use, often while you are smoking. Your body reacts to the drug being introduced into your system by pumping up your heart rate. As you may know, your heart needs to keep a certain rhythm to be healthy. Speeding it up during exercise is a good workout for your heart, but it is unhealthy for your heart rate to increase very much when you are inactive. And that is exactly the state of most people while they are smoking. They are simply relaxing, but their heart rate is faster than it should be.
This can cause long-term heart problems, which include cardiac infarction, heart disease and more. The longer you smoke, the more stress you are putting on your heart and the greater your risk of a heart problem.
Nicotine also stimulates your respiratory and vascular system. People who are craving nicotine may have a faster breathing rate. Their anxiousness and nervousness caused by the craving will make them breathe irregularly. This limits their physical abilities and in some ways cripples them, making them helpless against the physical effects of their addiction.
An increase of blood pressure, which is standard for nicotine users, is also dangerous. This puts your heart at risk and creates an unhealthy environment for many of your bodily systems.
It is important to understand that nicotine is both a stimulant and a sedative. While it creates stimulating effects, it also relaxes the body and creates a state of gentle euphoria. This is part of what makes it so addictive. That buzz that many smokers feel makes the other effects feel not as strong. The higher the concentrations of nicotine are, the greater the sense of euphoria will be.
Nicotine also activates the portion of the bran that rewards the body. This reward center is responsible for a lot of the motivation people feel. Regular nicotine users feel like they need that cigarette as a reward for getting through the day, surviving a few hours of work or for passing a test. They will say that the nicotine relaxes them, though in many ways it does the exact opposite. What it actually does it make them feel like they are being treated or rewarded by having that cigarette.
This causes severe addiction, and any of the people who try to quit do not succeed because of it.
… Or s it a Drug?
Those who say that nicotine is not a drug are likely trying to say that it is not a hard drug like cocaine or PCP. But it is most definitely a drug, as a drug is defined as any substance that has a physiological effect on the body when ingested or otherwise deposited into the body.
What that means is that the substance changes the way the body is functioning or would function naturally. This is something that doesn’t provide anything the body needs but is introduced to change the way the body is operating. That is why its good to know whether is Nicotine a Drug.
Most people understand that nicotine is addictive. It creates both physical and mental addiction. Withdrawal from the drug produces a number of symptoms, including anxiousness, nervousness, shaking, moodiness, depression, inattentiveness, and cravings. Those who smoke for a while then quit find themselves struggling to overcome these side effects and beat their cravings.
It is difficult for those who have become addicted to cease their habit. They often require outside help in the form of counseling, therapy or coaching to assist them in quitting their nicotine addiction.
The pharmacologic effects are those that are produced when small amounts of the drug are introduced into the body. With nicotine, these include an increased heart rate, higher heart stroke volume and an increase in how much oxygen is consumed by the heart. Basically, your heart is working overtime when nicotine is inside your body. This stresses the heart unnecessarily, and continued stress can lead to the development of heart problems.
Psychodynamic effects are similar to psychological effects. They change your mental state. With nicotine, these effects are a sense of euphoria, increased awareness and a state of relaxation.
How Addictive Is Nicotine?
Humans can experience addiction in two ways: psychological addiction and physical addiction. An example of psychological addiction is doing something extremely thrilling, e.g. gambling, bungee jumping, skydiving, driving too fast. These activities trigger reward centers of the brain, however, don’t have any physical impact on the body. We can relate it to classical conditioning as shown by Pavlov’s dog experiment, where dog started to associate certain signals (such as the ringing of a bell) with food and would start drooling on those signals, even when there was no food.
On the other hand, physical addictions tend to result in physical withdrawal symptoms, e.g. when a person suddenly stops drinking or taking a drug they’re addicted to. What really makes nicotine extremely addictive is that it’s one of the very few addictions that has both physical and psychological impact. On top of that, it also has social impact i.e. when you meet your other smoker friends, you start getting the urge to smoke (or use vapor cigarettes). So, in addition to affecting you physiologically, nicotine also affects you socially, and this is why most experts agree that nicotine is one of, if not the, hardest addictions to break.
