Smoking and Anxiety: 5 Proven Reasons Cigarettes Make It Worse
By Michael Whelehan | Certified Master Hypnotherapist and Master NLP Practitioner | Breathe Hypnotherapy Melbourne | Updated May 2026
Most people who smoke reach for a cigarette when they feel anxious. It feels like relief. It works, at least for a few minutes. But research consistently shows that smoking and anxiety are trapped in a cycle where each one makes the other worse, not better.
Understanding this cycle is one of the most important things a smoker can know. The moment you realise that cigarettes are not calming your anxiety but feeding it, everything changes.
Many of the patterns behind this cycle are explored in our earlier article Does Smoking Relieve Stress? The Truth Might Surprise You.
Quick Answer: Does Smoking Cause Anxiety?
Yes. The link between smoking and anxiety is well established in research. While nicotine temporarily eases withdrawal discomfort, regular smoking raises your baseline anxiety level over time. Studies show smokers experience significantly higher rates of anxiety than non-smokers, and that successfully quitting smoking is associated with lasting reductions in anxiety, depression, and stress. The calm you feel after a cigarette is not relaxation. It is withdrawal relief.
What Is the Connection Between Smoking and Anxiety?
The connection between smoking and anxiety is well documented and runs deeper than most smokers realise.
A landmark study published in Psychological Medicine tracked over 1,000 adults and found that people who quit smoking reported lower levels of anxiety, depression, and stress compared to those who continued. Critically, these improvements appeared in both the general population and in people with pre-existing mental health conditions, meaning quitting helps even when anxiety is pre-existing.
The Australian Institute of Health and Welfare reports that psychological distress is significantly more common in current smokers than in non-smokers or former smokers. This is not a coincidence. It reflects how nicotine changes brain chemistry over time.
The relationship between smoking and anxiety has been studied extensively, and the findings are consistent: nicotine dependence and elevated anxiety tend to occur together and reinforce each other.
Key facts about smoking and anxiety:
- Smokers are approximately twice as likely to experience anxiety disorders compared to non-smokers, according to a 2020 review in the Journal of Psychiatric Research
- Nicotine activates the amygdala, the brain’s fear and stress processing centre, increasing sensitivity to anxiety triggers with repeated exposure
- Around 11% of Australian adults currently smoke, according to AIHW data, and rates of psychological distress are disproportionately higher in this group
For many smokers, anxiety and cigarettes are so intertwined it can be difficult to separate one from the other. That is exactly what makes this cycle so hard to break through willpower alone.
Does Nicotine Relieve Anxiety or Create It?
This is the central confusion for most smokers, and it deserves a direct answer.
Nicotine does produce short-term relief. This is real and measurable. It triggers dopamine release and briefly activates reward pathways in the brain. But the anxiety you feel before lighting a cigarette was largely created by nicotine itself.
This is the central paradox of smoking and anxiety. The substance you are using to feel calmer is the same substance responsible for the agitation you feel without it.
Within 20 to 30 minutes of finishing a cigarette, nicotine levels in your blood begin to drop. Your brain, now accustomed to regular nicotine input, begins signalling distress. That agitation, restlessness, and unease is nicotine withdrawal. It is chemically similar to anxiety.
When you smoke, you are not calming anxiety. You are temporarily ending withdrawal symptoms that smoking created in the first place.
Non-smokers exposed to the same daily stressors, the same work pressure, the same traffic, the same difficult conversations, do not experience this cycle. Their brains have not adapted to require regular nicotine input to feel functional.
The Better Health Channel Victoria describes nicotine dependence as a cycle of craving, temporary relief, and return to craving, one that mimics and amplifies anxiety symptoms over time.
Why Do You Feel Calmer After a Cigarette?
Understanding this mechanism removes a great deal of the confusion smokers carry about why they believe they need cigarettes to cope.
Here is what actually happens in sequence:
- Nicotine enters the bloodstream within seconds of inhalation
- The brain’s reward pathways activate, releasing dopamine
- Withdrawal symptoms, including anxiety-like agitation, temporarily ease
- The feeling is interpreted as calm or relief
- Nicotine levels drop again within 30 to 60 minutes
- The cycle restarts
The deep breathing involved in smoking also plays a role. Slow, diaphragmatic breathing, the kind you use when drawing on a cigarette, activates the parasympathetic nervous system, which genuinely reduces stress. Part of what smokers experience as the calming effect of a cigarette is actually the calming effect of deep breathing. You can replicate this completely without the cigarette.
Once you see this sequence clearly, the smoking and anxiety cycle loses much of its power. You are not managing anxiety with a cigarette. You are managing a chemical dependency your brain has built around it.
How Does Quitting Smoking Affect Your Anxiety?
The smoking and anxiety cycle does not break instantly, but it does break. Here is what the research shows across three timeframes.
Many smokers avoid quitting because they fear their anxiety will get worse. This concern is understandable, and the evidence is worth being honest about.
Short term (weeks one to four): Some people experience increased irritability and restlessness as the brain adjusts to operating without nicotine. These feelings are real, they are temporary, and they are not a sign that quitting is making things worse long-term. They are withdrawal.
Medium term (one to three months): The brain’s chemistry begins to normalise. Former smokers typically report significant reductions in baseline anxiety, improved mood stability, and a greater sense of emotional control.
Long term (six months and beyond): Multiple large studies consistently show that successful quitters report better mental health outcomes than when they were smoking. The anxiety cycle is broken, and the brain is no longer dependent on regular nicotine input to feel functional.
Quit Victoria confirms that most people feel meaningfully better mentally and emotionally within four to eight weeks of stopping smoking.

Can Hypnotherapy Help With Smoking-Related Anxiety?
Hypnotherapy for smoking cessation works differently from other quit methods. Rather than substituting or suppressing nicotine cravings, it aims to work with the subconscious patterns, habits, and associations that keep the smoking and anxiety cycle running.
For individuals where anxiety is a core driver of smoking, hypnotherapy may:
- Help interrupt the automatic response of reaching for a cigarette during stressful moments
- Build new mental associations between stress and non-smoking coping responses
- Reduce the fear and apprehension that can surround the idea of quitting
- Address the belief that cigarettes are necessary for managing emotions
It is important to note that hypnotherapy is not a treatment for clinical anxiety disorders. If you have a diagnosed anxiety condition, such as generalised anxiety disorder or panic disorder, please continue working with your GP or mental health professional. Hypnotherapy may work alongside, not instead of, that support.
Results differ between individuals and no outcome can be guaranteed. Many clients find hypnotherapy a valuable addition to their quit-smoking plan, particularly where emotional patterns and habitual responses are driving the behaviour.

Frequently Asked Questions About Smoking and Anxiety
Does smoking cause anxiety?
Research shows a consistent association between regular smoking and higher rates of anxiety disorders. While the relationship is complex, the evidence suggests that nicotine dependency raises your baseline anxiety level over time. The temporary calm smokers feel after a cigarette is withdrawal relief, not genuine anxiety reduction. Long-term smokers tend to experience more anxiety overall than non-smokers. Addressing the smoking and anxiety connection directly, rather than treating them as separate issues, tends to produce better outcomes for people who smoke in response to stress.
Does quitting smoking increase anxiety?
Some people experience irritability and discomfort in the first two to four weeks of quitting. This is a normal part of nicotine withdrawal and is temporary. The long-term evidence is clear: quitting smoking is associated with significant reductions in anxiety, stress, and depressive symptoms. Most former smokers report improved mental wellbeing within four to eight weeks.
How long does anxiety last after quitting smoking?
Withdrawal-related anxiety and irritability typically peak in the first one to two weeks and ease progressively over the following weeks. Most former smokers notice a meaningful improvement in their baseline mood and anxiety levels within four to eight weeks of their quit date.
Can hypnotherapy help reduce anxiety when quitting smoking?
Hypnotherapy may help some individuals manage the psychological and habit-based aspects of quitting, including anxiety about the process and the emotional patterns that drive smoking. It is not a clinical treatment for anxiety disorders. For anyone with a diagnosed anxiety condition, hypnotherapy should complement, not replace, existing medical or psychological support.
Is it normal to feel more anxious without a cigarette?
Yes, and this is actually a sign that nicotine dependence is at work. The smoking and anxiety feedback loop means your nervous system has been recalibrated around nicotine. The anxiety felt between cigarettes is the brain signalling withdrawal, not evidence that you need to smoke. Recalibrating back takes weeks, not days, but it does happen, and most former smokers report that their baseline anxiety drops significantly once the adjustment is complete.
