Can A Cigar Make You Sick? | The Health Facts

Understanding how cigars interact with our bodies is important for anyone considering them. We are here to talk through the facts, helping you grasp the real health implications of cigar use, both in the short term and over time.

Immediate Effects and Acute Sickness

Even a single cigar can trigger noticeable physical responses, often making someone feel unwell. This immediate sickness stems primarily from the rapid absorption of nicotine and exposure to other toxins like carbon monoxide.

When you smoke a cigar, nicotine is absorbed through the mucous membranes in your mouth, even if you do not inhale. This can lead to a sudden rush, followed by symptoms such as:

• Nausea and Upset Stomach: Nicotine can irritate the digestive system.
• Dizziness and Lightheadedness: Nicotine affects the central nervous system, and carbon monoxide reduces oxygen delivery to the brain.
• Headache: Blood vessel constriction and oxygen deprivation contribute to head pain.
• Increased Heart Rate and Blood Pressure: Nicotine acts as a stimulant, putting strain on the cardiovascular system.
• Throat Irritation and Coughing: Smoke contains irritants that inflame the respiratory lining.

These acute reactions are your body’s way of signaling distress, indicating that it is encountering harmful substances. The intensity of these symptoms can vary based on the cigar’s size, nicotine content, and the individual’s tolerance.

Long-Term Health Risks: Beyond the Immediate

While the immediate sickness can be unpleasant, the long-term health consequences of cigar smoking are far more severe and pervasive. Regular cigar use significantly elevates the risk for a range of chronic diseases, impacting nearly every major organ system.

Many people mistakenly believe cigars are safer than cigarettes because they are not typically inhaled deeply. However, even without deep inhalation, the harmful chemicals in cigar smoke are absorbed through the mouth and throat, entering the bloodstream and affecting the entire body.

Oral and Upper Respiratory Cancers

The constant exposure of the mouth, throat, and esophagus to cigar smoke creates a high risk for various cancers. These include:

• Oral Cancer: Affecting the lips, tongue, cheeks, floor of the mouth, hard and soft palate.
• Throat Cancer (Pharyngeal Cancer): Developing in the pharynx, the tube behind the mouth and nasal cavity.
• Esophageal Cancer: Occurring in the tube connecting the throat to the stomach.
• Laryngeal Cancer: Cancer of the voice box.

These cancers are often aggressive and can necessitate extensive treatment, severely impacting quality of life. The risk increases with the frequency and duration of cigar use.

Lung Cancer and Respiratory Disease

Even if not deeply inhaled, cigar smoke still reaches the lungs. People who regularly smoke cigars have a higher risk of lung cancer than non-smokers. Cigar smoking also contributes to chronic respiratory conditions.

• Chronic Obstructive Pulmonary Disease (COPD): A progressive lung disease that makes breathing difficult, including chronic bronchitis and emphysema.
• Asthma Exacerbation: Irritants in cigar smoke can trigger or worsen asthma attacks.

Understanding Cigar Composition and Harmful Chemicals

Cigars are not just dried tobacco leaves; they are complex products containing a multitude of chemical compounds, many of which are toxic and carcinogenic. The manufacturing process, including fermentation and aging, can even increase the concentration of certain harmful substances.

A typical cigar contains more tobacco than a cigarette, sometimes as much as an entire pack. This means a single cigar can deliver a much higher dose of harmful chemicals and nicotine.

Key Toxic Components

The combustion of tobacco in cigars releases thousands of chemicals, including many known carcinogens and toxins. Some of the most concerning include:

1. Nicotine: The highly addictive substance that causes dependence. It also elevates heart rate and blood pressure, constricting blood vessels.
2. Tar: A sticky, black substance containing numerous carcinogens. It coats the lungs and mouth, leading to cell damage and mutations.
3. Carbon Monoxide: A colorless, odorless gas that reduces the oxygen-carrying capacity of blood, straining the heart and brain.
4. Tobacco-Specific Nitrosamines (TSNAs): Potent carcinogens formed during the curing and burning of tobacco. Cigar tobacco often contains higher levels of TSNAs than cigarette tobacco.
5. Polycyclic Aromatic Hydrocarbons (PAHs): A group of chemicals formed during incomplete combustion, many of which are known carcinogens.
6. Heavy Metals: Cadmium, lead, and arsenic are present in tobacco and can accumulate in the body, causing organ damage.

These chemicals do not just affect the lungs; they are absorbed into the bloodstream and distributed throughout the body, contributing to systemic health problems.

Immediate Effects of Cigar Use

Symptom	Primary Cause
Nausea	Nicotine irritation of digestive system
Dizziness	Nicotine’s CNS effects, carbon monoxide reducing oxygen
Headache	Blood vessel constriction, oxygen deprivation

Cardiovascular and Other Systemic Risks

The impact of cigar smoking extends significantly to the cardiovascular system, increasing the risk of serious heart and blood vessel conditions. The chemicals in cigar smoke damage blood vessel walls, promote plaque buildup, and interfere with normal heart function.

Heart Disease and Stroke

Cigar users face elevated risks for:

• Atherosclerosis: Hardening and narrowing of the arteries due to plaque buildup, restricting blood flow.
• Heart Attack: Occurs when blood flow to a part of the heart is blocked, often by a blood clot.
• Stroke: Happens when blood flow to the brain is interrupted, either by a clot or a burst blood vessel.
• Aortic Aneurysm: Weakening and bulging of the aorta, the body’s main artery, which can be life-threatening if it ruptures.

These conditions are directly linked to the effects of nicotine, carbon monoxide, and other toxins on blood pressure, cholesterol levels, and blood clotting mechanisms. The Centers for Disease Control and Prevention (CDC) provides extensive information on tobacco’s impact on cardiovascular health.

Other Systemic Impacts

Beyond the heart and lungs, cigar use can negatively affect other organs:

• Pancreatic Cancer: Studies show a connection between cigar smoking and an increased risk of pancreatic cancer, a particularly aggressive form.
• Kidney Disease: Toxins can damage kidney function over time.
• Erectile Dysfunction: Impaired blood flow due to vascular damage can lead to difficulties.
• Reduced Immune Function: Weakening the body’s ability to fight off infections and diseases.

The Addictive Nature of Nicotine

Nicotine is a powerful, highly addictive chemical found naturally in tobacco. Regardless of the delivery method – cigarette, cigar, or other tobacco products – nicotine creates physical dependence. Even if cigar smoke is not inhaled, nicotine is readily absorbed through the oral mucosa.

When nicotine enters the bloodstream, it quickly reaches the brain, where it binds to receptors and triggers the release of neurotransmitters like dopamine. This creates a temporary feeling of pleasure and reward, reinforcing the desire to use tobacco again. This cycle is the foundation of addiction.

Nicotine Absorption in Cigar Smoking

Cigars typically have a higher pH than cigarettes, especially larger ones. This higher alkalinity means nicotine is present in an un-ionized form, which is more easily absorbed through the mucous membranes of the mouth. This allows significant nicotine absorption even without inhalation.

A single large cigar can deliver as much nicotine as several cigarettes. This high dose, combined with the efficient oral absorption, can quickly lead to nicotine dependence, making it difficult to stop using cigars.

Key Harmful Chemicals in Cigars

Chemical	Primary Health Impact
Nicotine	Addiction, increased heart rate/blood pressure
Tar	Carcinogenic, coats respiratory system
Carbon Monoxide	Reduces oxygen in blood, strains heart/brain

Secondhand and Thirdhand Smoke Concerns

The health risks associated with cigars are not limited to the person smoking. The smoke produced by cigars, often dense and lingering, poses significant threats to those nearby, known as secondhand smoke, and even to surfaces, known as thirdhand smoke.

Secondhand Smoke Exposure

Secondhand cigar smoke contains the same toxic and carcinogenic chemicals that the smoker inhales. Because cigars are often larger and burn for longer, they can produce more secondhand smoke than cigarettes. This smoke can lead to serious health problems for non-smokers, particularly children and individuals with pre-existing conditions.

• Respiratory Issues: Increased risk of asthma attacks, bronchitis, and pneumonia in children.
• Heart Disease: Non-smokers exposed to secondhand smoke have an increased risk of heart disease.
• Cancer: Exposure to secondhand smoke is a known cause of lung cancer in non-smokers. The National Cancer Institute (NCI) provides extensive data on this risk.

Ventilation systems do not fully eliminate the dangers of secondhand smoke; the most effective protection is a smoke-free environment.

Thirdhand Smoke Risks

Thirdhand smoke refers to the residual contamination from tobacco smoke that clings to surfaces like clothing, furniture, walls, and carpets long after a cigar has been extinguished. These residues react with other compounds in the air to form new, even more toxic substances.

• Exposure Pathways: People, especially young children, can be exposed by touching contaminated surfaces and then putting their hands in their mouths, or by inhaling off-gassed chemicals.
• Persistent Toxins: Thirdhand smoke can be difficult to remove, persisting for weeks or months and continuing to release harmful chemicals into the air.

This silent threat underscores that the effects of cigar smoke extend far beyond the immediate act of smoking, impacting the health of an entire household or shared space.
