Can quitting smoking lead to depression?


Hello Dr.
Tang: I have been smoking for 11 years, about a pack a day, but I quit half a month ago because I have been exercising and want to improve my physical fitness.
However, since I stopped smoking, I haven't had the urge to sneak a smoke or any cravings, but my mind has been racing with thoughts, I feel restless, and I have trouble concentrating.
Sometimes I even experience insomnia.
I am concerned that I might be developing depression and fear that I can't control my behavior.
I feel inexplicably down and frustrated.
I sometimes wonder if I have been exposed to something harmful, or if this is a normal phenomenon.
My racing thoughts tend to focus on negative things, which is unusual for me; in the past, when I had racing thoughts, I would quickly think of happier things, but now I find myself constantly overthinking.
It's really bothersome.
Additionally, I sometimes feel chest tightness, but I believe that without smoking, my breathing should be smooth.
Why does it feel less smooth than when I was smoking? I constantly feel a sense of pressure from my surroundings, which is suffocating.
Maybe it's just too hot these days.
In summary, I feel very troubled.
Please help me.

Dr. Tang Xinbei reply Smoking Cessation


Dear friend: I am glad that you are willing to start working towards overcoming the dangers of smoking.
Of course, at the beginning, there will always be some discomfort testing the determination and willpower of those trying to quit.
According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, published by the American Psychiatric Association in 1994, the early stages of smoking cessation (approximately one to two weeks) may present the following eight withdrawal phenomena or symptoms associated with abrupt cessation or significant reduction in use: (1) mood disturbances or feelings of sadness, (2) insomnia, (3) irritability, frustration, or anger, (4) anxiety, (5) difficulty concentrating, (6) restlessness, (7) decreased heart rate, and (8) increased appetite or weight gain.
It seems that you may be experiencing at least three to four of these symptoms, which could indicate a diagnosis of "nicotine dependence." Many studies have also identified other withdrawal symptoms, such as dry mouth, vivid dreams, headaches, tingling sensations in the skin, and cravings for cigarettes.
Research abroad has found that "smoking cessation is associated with depressive symptoms": individuals with a history of major depressive disorder tend to have a higher level of nicotine dependence; furthermore, nicotine-dependent individuals with a history of major depressive disorder exhibit more pronounced depressive symptoms during cessation, which can trigger episodes of depression and lead to a higher failure rate in quitting.
I wonder if you or anyone in your family has a history of depression? If your symptoms persist for more than two weeks, I recommend visiting a psychiatrist at a hospital for a thorough evaluation and necessary assistance from professional healthcare providers.
Wishing you peace, joy, and success in quitting smoking!

Quitting smoking can indeed lead to a variety of emotional and psychological symptoms, including anxiety, irritability, and even depression. This is particularly true for individuals who have been smoking for an extended period, as nicotine addiction can create a dependency that affects both the body and mind. When you stop smoking, your body goes through withdrawal, which can manifest in several ways, including the symptoms you are experiencing: racing thoughts, difficulty concentrating, insomnia, and feelings of unease.

The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) outlines that withdrawal from substances like nicotine can lead to mood disturbances. In your case, the symptoms of anxiety and irritability you are experiencing are common during the initial weeks of quitting smoking. Studies have shown that individuals with a history of depression or anxiety disorders may be more susceptible to experiencing heightened emotional distress during this period.
It's important to recognize that while these feelings can be distressing, they are often temporary and part of the body's adjustment to the absence of nicotine. However, if these symptoms persist beyond a couple of weeks or worsen, it may be indicative of a more serious issue, such as the onset of depression. The feelings of hopelessness, persistent sadness, and lack of interest in previously enjoyable activities are key indicators of depression.
You mentioned that you sometimes feel chest tightness and that your breathing seems less smooth than when you were smoking. This could be due to several factors. First, your body is adjusting to the absence of nicotine, which can affect your respiratory system. Additionally, anxiety can manifest physically, leading to sensations like chest tightness and difficulty breathing. It’s crucial to differentiate between anxiety-related symptoms and potential physical health issues, so consulting a healthcare professional is advisable.

To address your concerns, here are some strategies that may help you cope during this challenging time:
1. Seek Professional Help: If your symptoms persist or worsen, consider reaching out to a mental health professional. They can provide a thorough evaluation and may suggest therapy or medication if necessary.

2. Practice Mindfulness and Relaxation Techniques: Techniques such as deep breathing, meditation, or yoga can help reduce anxiety and improve your overall mood. These practices encourage relaxation and can help you regain focus.

3. Stay Active: Regular physical activity can significantly improve your mood and reduce feelings of anxiety. Exercise releases endorphins, which are natural mood lifters.

4. Connect with Support Groups: Engaging with others who are also trying to quit smoking can provide emotional support and practical tips. Many communities offer smoking cessation programs that include counseling.

5. Consider Nicotine Replacement Therapy (NRT): If you find the withdrawal symptoms overwhelming, NRT options like patches or gum can help ease the transition by providing a controlled dose of nicotine without the harmful effects of smoking.

6. Maintain a Healthy Routine: Establishing a daily routine that includes balanced meals, regular sleep, and scheduled activities can help stabilize your mood and provide a sense of normalcy.

7. Limit Caffeine and Alcohol: Both substances can exacerbate anxiety and disrupt sleep patterns, so it may be beneficial to reduce your intake during this period.

In summary, while quitting smoking can lead to emotional challenges, these symptoms are often temporary and manageable with the right support and strategies. If you find that your feelings of anxiety and depression persist, do not hesitate to seek professional help. Remember, you are not alone in this journey, and many resources are available to support you in achieving a smoke-free life.
