Why People with Bipolar Disorder Smoke More Often

The numbers are even more striking in clinical studies. Some research suggests that up to 70% of individuals with bipolar disorder smoke at some point in their lives, compared to about 25-30% of the general population. People with bipolar also tend to smoke more heavily — often 1.5 to 2 packs per day — and have lower quit rates. This is one of the largest health disparities in psychiatry.

The leading theory for why people with bipolar disorder smoke so heavily is self-medication. Nicotine affects several neurotransmitter systems involved in mood regulation: dopamine, serotonin, norepinephrine, and acetylcholine. For someone with bipolar, nicotine can temporarily alleviate depressive symptoms and reduce manic agitation — but this relief comes at a terrible cost.

• 😔 Depression relief: Nicotine increases dopamine and norepinephrine, which can briefly lift mood. Many people with bipolar report that smoking helps them “get out of bed” during depressive episodes.
• 🌪️ Mania/agitation reduction: For some, nicotine has a paradoxical calming effect during manic or mixed episodes, reducing racing thoughts and restlessness.
• ⚖️ Mood stabilization? Some research suggests that nicotine may help regulate circadian rhythms and sleep-wake cycles — both disrupted in bipolar disorder.
• 🔄 The trap: The relief is temporary and followed by withdrawal symptoms (irritability, anxiety, low mood) that worsen the underlying bipolar symptoms — leading to more smoking.

Bipolar disorder and nicotine addiction share common neurobiological pathways, particularly involving the dopaminergic system. The same genes that increase susceptibility to bipolar disorder may also increase susceptibility to nicotine dependence. This is not a moral failing — it’s biology.

• 🧬 Genetic overlap: Studies of identical twins have shown that the genetic risk for bipolar disorder and the genetic risk for heavy smoking are correlated. Some of the same gene variants are involved.
• ⚡ Dopamine dysregulation: Bipolar disorder involves abnormal dopamine transmission. Nicotine artificially boosts dopamine — providing temporary “normalization” that the bipolar brain craves.
• 🔁 The reward circuit: The brain’s reward system (nucleus accumbens, ventral tegmental area) is dysfunctional in bipolar disorder. Smoking is a way to force that reward circuit to fire — but it’s a crude and destructive tool.
• 📉 Implication: Because the biological underpinnings are shared, quitting smoking is harder for someone with bipolar — not because of weakness, but because of brain chemistry.

Nicotine induces the liver enzyme CYP1A2, which breaks down several psychiatric medications — including clozapine, olanzapine, and some antidepressants. Smokers with bipolar often require significantly higher doses of these medications to achieve the same effect as non-smokers. When they try to quit, medication levels can spike dangerously.

• 📈 Higher doses: Smokers with bipolar may need 30-50% higher doses of certain antipsychotics and mood stabilizers.
• ⚠️ Quitting without medical supervision: When a smoker quits, nicotine levels drop, CYP1A2 activity decreases, and medication levels rise — potentially causing toxicity. This is why people with bipolar should never quit smoking abruptly without consulting their psychiatrist.
• 🔄 Vicious cycle: Because smoking affects medication levels, some psychiatrists hesitate to encourage quitting until mood is stable. But waiting for “perfect stability” may never happen.
• 📋 The solution: Coordinated care — a psychiatrist adjusts medications before, during, and after a quit attempt.

People with severe mental illness, including bipolar disorder, face higher rates of unemployment, poverty, and housing instability. These social determinants of health drive smoking in several ways: stress, limited access to cessation programs, and the availability of cheaper native cigarettes.

• 💰 Lower income: Many people with bipolar are on disability or work lower-wage jobs. Native cigarettes ($29-50 per carton) are much more affordable than commercial brands ($150-220).
• 🏥 Poor access to cessation support: Mental health care is already underfunded. Specialized smoking cessation programs for people with bipolar are almost non-existent in Canada outside of major cities.
• 📉 Chronic stress: The stress of managing a chronic mental illness increases smoking rates across all psychiatric populations.
• 🌾 Rural factor: People with bipolar in rural Canada have even higher smoking rates due to isolation and fewer resources.

People with bipolar disorder want to quit smoking as much as anyone else. But they face unique barriers:

• 😖 Nicotine withdrawal mimics bipolar relapse: The irritability, insomnia, anxiety, and mood swings of withdrawal look exactly like a bipolar mood episode. Many people with bipolar (and their doctors) mistake withdrawal for relapse — and resume smoking to feel better.
• ⚠️ Fear of triggering mania or depression: Some people with bipolar have tried to quit in the past and experienced severe mood episodes as a result. This creates fear — and understandable reluctance to try again.
• 💊 Medication adjustment required: As discussed, quitting changes medication levels. Many psychiatrists lack experience with this, leaving patients without proper support.
• 📉 Lower quit success rates: In general population studies, 5-7% of unaided quit attempts succeed. Among people with bipolar, success rates are 2-3% without specialized support.

Many people with bipolar disorder who smoke have switched to native cigarettes — not because they are “safer” (they are not), but because of cost and availability. On disability income or limited wages, a $35 carton of Playfare or Canadian Full is a necessity, not a choice. Commercial cigarettes at $18-22 per pack would consume an unsustainable portion of a fixed income.

• 💰 Cost savings: A pack-a-day smoker saves $5,000-7,000 per year by switching to native brands.
• 📦 Online delivery: Cigstore.ca ships to any address — essential for people with mobility challenges or who live in rural areas with limited access to stores.
• ⚖️ No judgment: Online ordering removes the potential stigma of buying cigarettes from a convenience store where clerks might know you.
• 💡 Important note: Switching to native cigarettes does not reduce health risks. The same toxins are present. But for those who cannot quit, affordable native cigarettes reduce financial stress — which itself is a mental health risk factor.
