Why Is It So Hard to Quit Smoking?

The majority of smokers find quitting incredibly tough, as many challenges come with giving up nicotine. Despite having the motivation to quit, most people will continue their same routine despite understanding the dangers associated with smoking.

So why is it so difficult to quit? In short, smoking cessation involves a combination of physical, psychological, social, and environmental aspects. In order to overcome the challenges of quitting smoking, they must first be understood.

The Power of Nicotine Addiction

Nicotine is a powerful chemical that causes physical and psychological addiction in smokers. Just one pull of a cigarette lets nicotine flow quickly into the bloodstream, reaching the brain within seconds [1].

The brain activates neurotransmitters, like dopamine, which is responsible for the feelings of pleasure and reward. The swift feeling of satisfaction is a primary reason why smoking is so addictive.

Nicotine is able to cross the blood-brain barrier and strongly impact the brain’s reward system. This continuously reminds the smoker of these euphoric feelings, which causes their bodies to crave nicotine in the form of a cigarette. The cycle of addiction begins when the brain starts to rely on nicotine to release dopamine. With each cigarette, it becomes even harder to break the habit [2].

Nicotine addiction is not merely physical; it is deeply psychological as well. Most daily routines and emotional coping mechanisms involve cigarettes for smokers.

People who smoke develop habits, such as having a cigarette with their first cup of coffee in the morning. These routines become established, and quitting might feel like someone is losing a piece of who they are.

Physical Nicotine Withdrawal Symptoms

Nicotine withdrawal is one of the most challenging things to experience while quitting smoking. When people do eventually stop the habit, the withdrawal effects are almost instant. But despite nicotine being an exceptionally addictive substance, when a smoker stops smoking for a few days, the body already starts to go through a massive change – for the better [3].

It can be overwhelming when trying to quit because the process may trigger all kinds of physical and emotional symptoms. Having a better understanding of these symptoms can help smokers feel strong enough to become smoke-free. Common nicotine withdrawal symptoms include:

Intense Cravings: The initial days or weeks are usually the most challenging, as cravings are high and the desire to smoke is severe. The brain is less able to regulate dopamine release that was previously stimulated by nicotine. With dopamine being released more slowly, people who quit smoking will experience strong and constant cravings.

  • Irritability and Anxiety: Nicotine alters the chemistry of the brain, and the sudden shortage of it can cause an emotional imbalance. Feelings of irritability, restlessness, or anger are common, as the body has become dependent on routine doses of nicotine.
  • Increased Appetite and Weight Gain: When a smoker quits, they may feel an increase in hunger and lean toward more calorie-dense, comfort-type foods. Nicotine is an appetite suppressant, and it speeds up metabolism. As a result, it is understandable that many people will gain weight after quitting smoking. However, this will stabilize over time.
  • Difficulty Concentrating: Without nicotine, the brain will need to adjust, which may cause difficulties when trying to focus and stay alert. However, this foggy experience will fade as the body adapts to the absence of nicotine.
  • Sleep Disturbances: Many people notice that their sleep patterns are disturbed as they quit smoking. It is often more difficult to fall asleep, and it is common to have vivid dreams and to wake up more often during the night. This is because the neurotransmitters that influence sleep are also affected by nicotine.

Withdrawal symptoms can be uncomfortable, but they indicate that the body is healing and detoxifying from the nicotine. You need to remember that the effects are temporary and will decrease as the body adjusts.

The first few days and weeks will bring with them significant symptoms, which can often cause people to relapse. These effects are only temporary effects and will decrease in time [4].

Social and Environmental Triggers

Very often, social settings and environmental changes can influence habits. These settings can be triggers for people who smoke. Environmental triggers include:

  • Social settings: It is extremely hard for someone who smokes to suppress the urge to light up a cigarette when smoking is the norm in their social circles.
  • Emotional states: Many people use smoking to ease uncomfortable feelings. These include stress, boredom, anxiety, and sadness.
  • Routine activities: Smoking can become a part of routine activities, such as driving to work or taking a break during work.

To successfully overcome these situations, people who smoke must understand why they will still suffer from nicotine cravings, even long after they have stopped smoking.

Is Smoking Addiction Genetic?

Smoking is primarily a personal choice, but research has proven that genetics may impact why some people smoke. These studies have determined that certain genes can also play a part in how people react to nicotine and how likely it is to cause addiction.

Certain genetic variations increase the pleasurable effect of smoking, making the risk of addiction higher. Some people may metabolize nicotine faster than others, making them desire more to keep the momentum going. With this being said, genetic factors only play a small role in increasing the risk of smoking [5].

The Impact of Previous Failed Quit Attempts

While it is completely possible to give up smoking after the first attempt, the majority of people require multiple attempts to successfully quit smoking. However, those initial failures make it even more difficult to try to quit again.

It is normal to feel discouraged, but there are important lessons that can be learned through each attempt. Every attempt is a step closer to the end goal, and these attempts should be viewed as stepping stones to success rather than setbacks.

How to Deal with Stress Without Cigarettes

Life is not easy. Stress is one of the top triggers for smoking, and many people use it as a crutch to deal with the stresses of their daily lives. Quitting, especially after relying on cigarettes for years, can prove to be very difficult.

However, there are many other ways to combat stress without reaching for a cigarette. Here are some alternatives:

  • Exercise: Exercise can be a wonderful stress reliever. For those trying to quit smoking, taking a walk, doing some yoga, or attending an aerobics session can help to elevate their mood. It also eases the symptoms of withdrawal.
  • Breathing and Mindfulness: Deep breathing, mindfulness, and meditation can help to ease anxiety in stressful situations. They also help to keep the mind in the present and manage anxiety without using nicotine.
  • Talking to someone: People who are trying to quit smoking should consider speaking to a friend or a family member if they feel that they need extra emotional support and motivation.
  • Hobbies and Activities: People who are trying to quit smoking should take part in hobbies and activities that resonate with them. This is an effective way to take the focus off smoking and to promote relaxation.

With the right amount of determination and patience, those who are trying to quit smoking will be able to form new habits that can complement their new non-smoking lifestyles.

Effective Strategies for Quitting

Everyone is different, and the journey to quitting smoking is a deeply personal one. People must find what works best for them. Some of the most effective methods are:

1. Nicotine Replacement Therapy (NRT)

There are several nicotine replacement products on the market. These products give those who want to quit smoking a controlled dose of nicotine. Nicotine replacement products are designed to supply nicotine without the harsh chemicals that are found in cigarettes.

NRT helps to relieve the symptoms of withdrawal, and products are sold in the form of gums, patches, lozenges, and nasal sprays. The design is to gradually reduce the use of nicotine replacement products until the dependence has been completely broken [6].

2. Prescription Medications

Two medications that work well to reduce the symptoms of withdrawal and cravings are varenicline (Chantix) and bupropion (Zyban or Wellbutrin). These work by altering how the brain responds to nicotine [7].

3. Behavioral Therapy

In some cases, working with a counselor or therapist can help people to understand what triggers them to want to smoke and help them develop other coping mechanisms. One therapy in particular, cognitive behavioral therapy (CBT), has been shown to be effective for those who want to quit [8].

4. Support Groups

Sharing experiences with others who are going through the same thing can be extremely motivating. Joining a support group is an effective way to receive accountability and encouragement.

5. Gradual Reduction

Trying to quit cold turkey can be a terrifying thought. Instead, people who smoke should try to reduce the number of cigarettes they smoke per day. This way, they can stay in control of the situation and gradually eliminate the use.

6. Mindfulness and Stress Management

It is important to incorporate practices of mindfulness into daily life. This is a fundamental part of finding healthy coping mechanisms when trying to quit cigarettes.

7. Setting a Quit Date

People looking to quit smoking should set a date in their calendar for when they are going to have their last cigarette. They should also plan for the cravings that they will endure and establish ways to handle the triggers. It is crucial to limit access to cigarettes at this point because if cigarettes are available, the urge to smoke (and having them around) will likely make the quitting attempt futile.

8. Rewarding Yourself

It is important for those trying to quit smoking to remind themselves of the progress that they have made. This can be done by recognizing the one-week mark, the two-week mark, the one-month mark, and others of being smoke-free, celebrating each milestone.

Why It’s Worth the Effort

Putting down a cigarette is hard; however, there is so much to gain. Within days, a person’s body will rejuvenate and begin to heal. Blood pressure and heart rate will start to stabilize, and lung function will improve. Additionally, the risk of cardiovascular disease will drop. In the long term, the risk of cancer, strokes, and smoking-related illnesses will also decrease dramatically.

Conclusion

People who stop smoking are improving their quality of life. They also benefit from avoiding the expenses and inconveniences of smoking.

Perhaps the best benefit is that people can add more years to their lives, giving them more time to spend with those that they love. Quitting smoking is, without a doubt, one of the toughest things a person can do, but it is also worth all the rewards.
