Tobacco Addiction: Symptoms, Causes, Effects, Treatment, and Preventions.

Tobacco addiction, also known as nicotine dependence, is a compulsive need to use tobacco products despite the awareness of associated health risks. Mainly linked with cigarette smoking, this addiction is characterized by an overwhelming urge to consume tobacco, often leading to adverse health outcomes. Individuals with tobacco addiction experience intense cravings, withdrawal symptoms upon cessation, and a persistent desire to continue tobacco use, even in the face of negative consequences.

The symptoms of tobacco addiction are varied and manifest in both physical and behavioral ways. Common signs include the inability to quit despite attempts, strong cravings for tobacco, continued use despite health problems, and prioritizing tobacco use over other activities or responsibilities. These symptoms often disrupt daily life and contribute to the cycle of addiction, making cessation challenging.

Various factors contribute to the development of tobacco addiction, including biological, psychological, and environmental influences. Biological causes involve the impact of nicotine on the brain’s reward system, while psychological factors such as stress and mental health disorders increase vulnerability. Additionally, environmental influences such as peer pressure and societal norms play a significant role in shaping tobacco use behaviors.

The effects of tobacco addiction are far-reaching and affect both physical and mental health. Long-term tobacco use increases the risk of various health conditions, including cancer, heart disease, and respiratory disorders. Additionally, tobacco addiction has detrimental effects on social relationships, finances, and overall quality of life.

Fortunately, there are treatment options available to help individuals overcome tobacco addiction. Behavioral therapies, such as cognitive-behavioral therapy and support groups, provide strategies for managing cravings and developing healthier coping mechanisms. Medications, including nicotine replacement therapy and prescription drugs, are often prescribed to aid in cessation efforts.

Preventing tobacco addiction involves a multi-faceted approach that addresses individual, community, and policy-level factors. Education and awareness campaigns help raise awareness of the dangers of tobacco use and promote healthy behaviors. Additionally, implementing policies such as tobacco taxes, advertising restrictions, and smoke-free laws creates environments that discourage tobacco use and support cessation efforts. 

What is Tobacco?

Tobacco is a plant native to the Americas and belongs to the genus Nicotiana. The most commonly used species of tobacco for commercial purposes is Nicotiana tabacum. Tobacco leaves contain nicotine, a highly addictive stimulant. Indigenous peoples have traditionally used tobacco for ceremonial, medicinal, and recreational purposes.

Is Tobacco Addictive?

Tobacco is highly addictive due to its nicotine content. Nicotine is a potent stimulant that affects the brain’s reward system, leading to the development of dependence and addiction. According to Hatsukami, D. K., Stead, L. F., & Gupta, P. C. et al. 2008, “Tobacco addiction,” when tobacco products are consumed, nicotine is rapidly absorbed into the bloodstream, reaching the brain within seconds.

Nicotine stimulates the release of neurotransmitters such as dopamine, which produce pleasurable sensations and reinforce the desire to use tobacco. Over time, repeated exposure to nicotine leads to changes in the brain’s chemistry, resulting in tolerance, dependence, and withdrawal symptoms when tobacco use is discontinued. 

Tobacco use is associated with 5 million deaths per year worldwide. It is considered one of the leading causes of premature death according to Hatsukami, D. K. et al. 2008, “Tobacco addiction: Diagnosis and treatment.” The addictive nature of tobacco makes it difficult for many people to quit smoking or using other tobacco products without assistance. 

WHAT ARE THE SIGNS AND SYMPTOMS OF TOBACCO ADDICTION?

Tobacco addiction manifests through various signs and symptoms, reflecting the physiological and psychological effects of nicotine dependence. These symptoms vary in severity and interfere with an individual’s health, well-being, and daily functioning. 

1. Strong Cravings for Tobacco

One of the hallmark symptoms of tobacco addiction is experiencing intense cravings for tobacco products. These cravings are overwhelming and difficult to resist, leading individuals to seek out and use tobacco despite their efforts to quit. Cravings often occur in response to triggers such as stress, social situations, or environmental cues associated with tobacco use. These cravings are driven by the addictive nature of nicotine, which stimulates the brain’s reward system and reinforces the desire to use tobacco.

2. Withdrawal Symptoms When Trying to Quit

Individuals attempting to quit tobacco experience withdrawal symptoms as their bodies adjust to the absence of nicotine. These symptoms vary in severity and include irritability, anxiety, depressed mood, difficulty concentrating, increased appetite, and sleep disturbances. Withdrawal symptoms are described as a common challenge faced by individuals trying to quit smoking or using other tobacco products. These symptoms contribute to relapse and make it challenging to maintain tobacco abstinence.

3. Continuing Tobacco Use Despite Health Problems

Despite being aware of the negative health consequences of tobacco use, individuals with tobacco addiction often continue to use tobacco products. This behavior persists even when faced with smoking-related illnesses such as lung cancer, heart disease, respiratory problems, and other health issues. 

4. Inability to Stop Using Tobacco Products

Another key symptom of tobacco addiction is the inability to stop using tobacco products despite repeated attempts to quit. Despite their desire to leave and the negative consequences of tobacco use, individuals struggle to maintain tobacco abstinence and find themselves relapsing into tobacco use. It reflects the cycle of addiction, where individuals make repeated attempts to quit but find themselves unable to overcome their tobacco dependence.

5. Prioritizing Tobacco Use Over Everything Else

Individuals with tobacco addiction alter their behavior to accommodate their tobacco use, such as giving up activities or avoiding places where tobacco use is prohibited. This includes preventing smoke-free environments or social situations where tobacco use is discouraged. Individuals with tobacco addiction prioritize their tobacco use over other activities and social interactions, reflecting the pervasive impact of tobacco addiction on various aspects of an individual’s life.

What are the Effects of Tobacco Addiction?

Tobacco addiction has multifaceted effects on both physical and mental health, as well as on social behavior. 

What Are The Physical Effects Of Tobacco Addiction?

The physical effects of tobacco addiction are profound and often detrimental to health. Smoking tobacco exposes individuals to a range of harmful chemicals, including nicotine, tar, and carbon monoxide. These substances lead to various health issues, such as:

• Respiratory Diseases: Tobacco smoke irritates the airways and damages the lungs, leading to conditions such as chronic bronchitis, emphysema, and lung cancer. It also exacerbates existing respiratory conditions like asthma.
• Cardiovascular Problems: Smoking significantly increases the risk of heart disease, stroke, and peripheral vascular disease. Nicotine and other chemicals in tobacco constrict blood vessels, raise blood pressure, and promote the formation of blood clots, all of which contribute to cardiovascular complications.
• Cancer Risk: The nicotine in tobacco is a leading cause of various cancers, including lung, throat, mouth, esophageal, bladder, and pancreatic cancer. According to Widysanto, A., & Combest, F. E. et al. 2023, “Nicotine Addiction,” the carcinogens in tobacco smoke directly damage DNA, leading to the uncontrolled growth of cancerous cells.
• Reproductive Issues: Smoking impairs fertility in both men and women and increases the risk of pregnancy complications such as miscarriage, preterm birth, and low birth weight. It also affects the quality of sperm and reduces fertility in men.
• Aging and Skin Damage: Tobacco use accelerates the aging process, leading to premature wrinkles, sagging skin, and a dull complexion. Smoking reduces blood flow to the skin, depriving it of oxygen and essential nutrients.

What Are The Mental And Cognitive Effects?

Beyond its physical toll, tobacco addiction also impacts mental health and cognitive function, as discussed by Elatfy, A., Vrahimis, S., Conti, A., & Baldacchino, A. et al. 2024, “Chronic tobacco smoking and neurocognitive impairments in adolescents and young adults: a systematic review and meta-analysis.” Some of the mental and cognitive effects include:

• Increased Risk of Depression and Anxiety: Research suggests that individuals who smoke are more likely to experience symptoms of depression and anxiety. Nicotine withdrawal symptoms exacerbate these mental health issues.
• Impaired Cognitive Function: Chronic tobacco use has been associated with cognitive decline and an increased risk of neurodegenerative diseases such as Alzheimer’s disease and dementia. Smoking impairs memory, attention, and executive function.
• Negative Mood Effects: While some individuals often use tobacco to alleviate stress or improve mood temporarily, long-term tobacco use leads to mood disturbances and irritability, particularly during periods of nicotine withdrawal.

What Are The Behavioral And Social Consequences Of Tobacco Use?

Tobacco addiction has far-reaching behavioral and social consequences, affecting various aspects of a person’s life:

• Social Isolation: Tobacco use leads to social isolation as individuals avoid smoke-free environments or activities where smoking is not permitted. Smokers also face stigma or disapproval from nonsmokers.
• Financial Strain: Supporting a tobacco addiction place a significant economic burden on individuals and families. The cost of purchasing tobacco products increases over time, impacting other areas of spending.
• Interpersonal Relationships: Tobacco addiction strains relationships with family members, friends, and romantic partners, particularly if nonsmokers are concerned about the smoker’s health or the effects of secondhand smoke.
• Employment Issues: Smoking impacts employment opportunities, as some employers prefer nonsmoking candidates due to concerns about productivity, absenteeism, and healthcare costs.

How Does Tobacco Affect The Brain?

Tobacco addiction profoundly affects the brain’s reward system and neurotransmitter activity. Nicotine, the primary addictive component of tobacco, acts on nicotinic acetylcholine receptors in the brain, leading to the release of dopamine and other neurotransmitters associated with pleasure and reward. This reinforcement mechanism reinforces the addictive cycle of tobacco use.

Additionally, chronic tobacco use leads to changes in brain structure and function, particularly in regions involved in decision-making, impulse control, and emotion regulation. These changes contribute to the development of addiction and make quitting tobacco use challenging for many individuals.

What are the Causes of Tobacco Addiction?

Understanding the causes of tobacco addiction involves examining a combination of biological, behavioral, and environmental factors:

What are the Biological Causes of Tobacco Addiction?

Biological factors play a significant role in the development of tobacco addiction, primarily through the effects of nicotine on the brain. Some key biological causes include:

• Neurochemical Changes: Nicotine, the primary psychoactive component of tobacco, interacts with nicotinic acetylcholine receptors in the brain, leading to the release of neurotransmitters such as dopamine, as discussed by Berrendero, F. et al. 2010, “Neurobiological mechanisms involved in nicotine dependence and reward: participation of the endogenous opioid system.” This neurotransmitter release results in feelings of pleasure and reward, reinforcing the addictive nature of tobacco use.
• Reward Pathway Activation: Nicotine’s repeated activation of the brain’s reward pathway leads to neuroadaptations, where the brain becomes less responsive to natural rewards. This desensitization increases the likelihood of continued tobacco use to maintain pleasurable feelings.
• Genetic Predisposition: Genetic factors influence an individual’s susceptibility to tobacco addiction. Variations in genes related to nicotine metabolism, receptor sensitivity, and reward processing increase the risk of developing dependence on tobacco products.

What are the Behavioral Causes of Tobacco Addiction?

Behavioral factors contribute to the initiation and maintenance of tobacco addiction, shaping patterns of use and dependence. These behavioral causes include:

• Social Learning: Tobacco addiction often begins through social learning processes, where individuals observe and imitate the behavior of peers, family members, or role models who use tobacco products. Positive reinforcement from social networks further reinforces smoking behavior.
• Psychological Coping Mechanisms: Some individuals turn to tobacco use as a means of coping with stress, anxiety, depression, or other negative emotions. Smoking often provides temporary relief or distraction from psychological distress, leading to the development of habitual use patterns.
• Conditioned Responses: Environmental cues and contexts associated with tobacco use, such as specific locations, activities, or times of day, become strongly linked to smoking behavior through classical conditioning. These cues trigger cravings and prompt relapse even after periods of abstinence.

What are the Environmental Causes of Tobacco Addiction?

Environmental influences are crucial in shaping attitudes, perceptions, and access to tobacco products. Ecological causes of tobacco addiction include:

• Social Norms and Peer Influence: Growing up in environments where tobacco use is normalized or socially accepted can increase the likelihood of tobacco experimentation and subsequent addiction. Peer pressure and social influences from friends or social circles also promote smoking initiation.
• Tobacco Marketing and Advertising: Extensive marketing efforts by tobacco companies glamorize and promote tobacco use, particularly among vulnerable populations such as youth and young adults. Advertising strategies, product placement, and sponsorship of events contribute to the normalization of smoking behavior.
• Availability and Accessibility: Easy access to tobacco products, including cigarettes, cigars, and smokeless tobacco, increases the likelihood of experimentation and regular use. The widespread availability of tobacco products in retail outlets, online platforms, and social settings facilitates access for individuals of all ages.

What are the Withdrawal Symptoms of Tobacco?

Tobacco withdrawal symptoms encompass a range of physical, psychological, and emotional manifestations that occur when individuals attempt to quit or reduce their tobacco use. According to Cui, Z. Y. et al. 2023, “The experience of tobacco withdrawal symptoms among current smokers and ex-smokers in the general population: Findings from nationwide China Health Literacy Survey during 2018-19,” tobacco abstinence is typically accompanied by urges to smoke, restlessness, hunger, irritability, and other adverse mood changes. These symptoms vary in intensity and duration, making quitting challenging.

Physical Symptoms of Withdrawal

• Intense Cravings: One of the hallmark symptoms of tobacco withdrawal is intense cravings for nicotine. These cravings are often overwhelming and difficult to ignore, usually leading individuals to relapse if not effectively managed.
• Headache: Many people experience headaches as a common withdrawal symptom when they attempt to quit tobacco. According to McLaughlin I. et al. 2015, “Nicotine Withdrawal,” these headaches vary in severity and persist for several days or weeks after cessation.
• Nausea: Some individuals often experience feelings of nausea or gastrointestinal discomfort as their body adjusts to the absence of nicotine. Nausea is a common symptom during the initial stages of withdrawal.
• Dizziness: Tobacco withdrawal also leads to feelings of dizziness or lightheadedness, particularly during periods of intense craving or nicotine deprivation. These sensations interfere with daily activities and require careful management.

Psychological Symptoms of Withdrawal

• Irritability and Mood Swings: Withdrawal from tobacco causes significant changes in mood, including irritability, agitation, and mood swings. According to Hughes, J. R., & Hatsukami, D. et al. 1986, “Signs and Symptoms of Tobacco Withdrawal,” these emotional fluctuations are often a result of nicotine’s impact on neurotransmitter levels in the brain.
• Anxiety and Restlessness: Many individuals experience heightened levels of anxiety and restlessness during tobacco withdrawal. These feelings are particularly pronounced in situations where individuals would typically smoke to alleviate stress or tension.
• Depression: Some people experience symptoms of depression, including feelings of sadness, hopelessness, or low energy, during tobacco withdrawal. These depressive symptoms are often temporary and typically improve over time.

Behavioral Symptoms of Withdrawal

• Difficulty Concentrating: Tobacco withdrawal impairs cognitive function and makes it challenging to concentrate or focus on tasks. This difficulty concentrating interferes with work, school, or other daily responsibilities.
• Increased Appetite: Many individuals experience an increase in appetite and food cravings during tobacco withdrawal. This phenomenon often contributes to weight gain in some individuals, especially if they turn to food as a substitute for tobacco.
• Insomnia or Sleep Disturbances: Difficulty sleeping is a common symptom of tobacco withdrawal, with many individuals experiencing insomnia or disrupted sleep patterns, according to Lape, E. C., & LaRowe, L. R. et al. 2021, “Tobacco cigarette smokers who endorse greater intolerance for nicotine withdrawal also report more severe insomnia symptoms.” These sleep disturbances exacerbate other withdrawal symptoms and impact overall well-being.

How to Manage Tobacco Withdrawal Symptoms

Managing tobacco withdrawal symptoms often requires a combination of strategies, including behavioral interventions, social support, and pharmacotherapy. Counseling, support groups, and nicotine replacement therapy (NRT) are commonly used to help individuals cope with cravings and other withdrawal symptoms.

It’s essential for individuals attempting to quit tobacco to seek support from healthcare professionals, friends, and family members to increase their chances of successfully overcoming withdrawal and achieving long-term tobacco cessation.

What are The Treatment Options for Tobacco Addiction?

Tobacco addiction is a complex issue that often requires a multifaceted approach to treatment. Fortunately, there are several effective treatment options available to help individuals overcome their addiction to tobacco. 

According to Elshatarat, R. A. et al. 2024, “Prevention, Control, and Treatment of Tobacco Use Addiction: A Literature Review Article,” effective treatment for tobacco addiction often involves a combination of behavioral therapies, medication, support groups, and individualized support to help individuals quit smoking or using other tobacco products and maintain long-term abstinence. 

Behavioral Therapies

• Cognitive-Behavioral Therapy (CBT): CBT is a type of psychotherapy that helps individuals identify and change the thoughts and behaviors that contribute to their tobacco use. By learning new coping strategies and techniques, individuals develop healthier habits and reduce their tobacco dependence.
• Motivational Interviewing (MI): MI is a client-centered counseling approach that enhances motivation and commitment to change. Therapists use techniques such as reflective listening and open-ended questions to help individuals explore their ambivalence about quitting smoking and build confidence in their ability to stop.

Is There a Safe Way to Smoke Cigarettes?

Smoking cigarettes is inherently harmful to health, and there is no safe way to smoke. Regardless of the method or frequency of smoking, the inhalation of tobacco smoke exposes the body to a wide range of toxic chemicals and carcinogens, leading to serious health consequences. Even individuals who smoke fewer cigarettes or use alternative smoking methods still face significant health risks associated with tobacco use.

Are Menthol Cigarettes Safer?

Contrary to popular belief, menthol cigarettes are not safer than non-menthol cigarettes, according to Lee, Y. O., & Glantz, S. A. et al. 2011, “Menthol: Putting the pieces together.” While menthol provides a cooling sensation and masks the harshness of tobacco smoke, it does not reduce the health risks associated with smoking. 

Menthol cigarettes are more harmful in some ways because menthol soothes the throat and decreases cough reflexes, allowing smokers to inhale more deeply and hold the smoke in their lungs longer. This results in increased exposure to toxic chemicals and carcinogens, further contributing to the development of smoking-related diseases.

WHAT ARE THE FACTS AND STATISTICS ON THE PREVALENCE OF TOBACCO ABUSE?

Tobacco abuse remains a global health crisis, claiming over 8 million lives annually, with half of its users dying prematurely, according to the World Health Organization (WHO) Report 2023. Around 22.3% of the world’s population, primarily in low- and middle-income countries, use tobacco, with men disproportionately affected. 

The WHO Framework Convention on Tobacco Control, ratified by 182 countries, addresses this epidemic. WHO’s MPOWER measures aim to reduce tobacco use through comprehensive strategies, saving lives and reducing healthcare costs. Urgent action is needed globally to implement effective policies and interventions to combat tobacco abuse and its devastating impact on public health.

WHERE DOES TOBACCO COME FROM?

Tobacco originates from the leaves of plants in the Nicotiana genus, part of the Solanaceae family. These plants are native to the Americas and were cultivated by indigenous peoples long before European colonization. After the arrival of Europeans in the Americas, tobacco became a major cash crop and was eventually introduced to regions worldwide. Today, tobacco is grown in various countries, with major producers including China, India, Brazil, and the United States.

HOW TO DIAGNOSE TOBACCO ADDICTION?

Diagnosing tobacco addiction involves a comprehensive assessment of an individual’s smoking habits, dependence level, and associated health risks. Here’s a detailed breakdown:

1. Clinical Interview:

• Smoking History: The healthcare provider will inquire about tobacco use frequency and duration.
• Nicotine Dependence: Various standardized scales like the Fagerström Test for Nicotine Dependence (FTND) are employed to assess the severity of addiction.
• Health Assessment: Evaluation of existing health conditions exacerbating smoking, such as cardiovascular or respiratory disorders.

2. Physical Examination:

• Vital Signs: Monitoring blood pressure, heart rate, and respiratory rate for any abnormalities associated with tobacco use.
• Respiratory Function: Assessing lung function through tests like spirometry to detect any impairment caused by smoking.

3. Laboratory Tests:

• Nicotine Levels: Measurement of nicotine and its metabolites in urine or blood samples to quantify tobacco exposure.
• Carbon Monoxide (CO) Levels: Breath tests to detect elevated CO levels, indicative of recent smoking.

4. Psychological Assessment:

• Screening for Mental Health Disorders: Identifying underlying conditions like depression or anxiety, which contribute to tobacco addiction.
• Behavioral Patterns: Understanding triggers, coping mechanisms, and motivations related to smoking behavior.

5. Diagnostic Criteria:

• DSM-4 Criteria: Meeting the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-4) for Tobacco Use Disorder, as mentioned in Hatsukami, D. K., & Stead, L. F. et al. 2008, “Tobacco addiction: Diagnosis and treatment.”

1. Chemical Composition: Nicotine is a psychoactive alkaloid found in tobacco plants, while caffeine is a natural stimulant found in coffee beans, tea leaves, and other sources.
2. Health Effects: While excessive caffeine consumption leads to health issues such as insomnia, anxiety, and heart palpitations, tobacco use is associated with far more severe health consequences, including cancer, cardiovascular disease, and respiratory disorders.
3. Legal Status: Caffeine is legal and widely available, whereas tobacco products are subject to legal restrictions and regulations in many countries due to their harmful effects.
4. Physical Dependence: Nicotine addiction often involves strong physical dependence, with users experiencing intense cravings and withdrawal symptoms, whereas caffeine addiction tends to be more psychological, with fewer severe physical withdrawal symptoms.
5. Social Impact: Tobacco addiction is often stigmatized and leads to social isolation, whereas caffeine addiction is generally more socially acceptable and is even encouraged in some social settings.

Which is more addictive: Nicotine or Caffeine?

Nicotine is generally considered to be more addictive than caffeine. Nicotine addiction is characterized by strong physical dependence and intense cravings, often leading to difficulties in quitting and higher rates of relapse compared to caffeine addiction. 

Additionally, nicotine has been shown to have a more pronounced impact on the brain’s reward pathways, contributing to its addictive nature. However, individual susceptibility to addiction varies, and some individuals often find caffeine more addictive depending on their genetic makeup and personal circumstances.

Can vaping or nicotine pouches helpful in quitting tobacco addiction?

Vaping is not a proven method for quitting tobacco addiction since it has at least as much nicotine as cigarettes. While some people use e-cigarettes as a cessation aid, they still contain nicotine and pose health risks. Similarly, nicotine pouches like Zyns are also addictive in the same way as cigarettes and just substitute one addiction for another in most cases.

How does tobacco addiction compare to ketamine addiction in terms of health risks and treatment options?

Tobacco addiction and ketamine addiction both pose significant health risks but in different ways. Tobacco addiction primarily affects the respiratory and cardiovascular systems, leading to diseases such as chronic obstructive pulmonary disease (COPD), lung cancer, and heart disease. Treatment for tobacco addiction often involves nicotine replacement therapy, medications like varenicline or bupropion, and behavioral support. Ketamine addiction, on the other hand, affects the brain’s neurotransmitter systems, potentially leading to cognitive impairments, bladder problems, and psychological issues like depression and dissociation. Treatment for ketamine addiction typically includes behavioral therapies, counseling, and support groups, as there are no FDA-approved medications specifically for ketamine addiction.

Can caffeine intake influence the severity of tobacco withdrawal symptoms?

Caffeine intake can influence the severity of tobacco withdrawal symptoms. Both nicotine and caffeine are stimulants, and their withdrawal symptoms can overlap, causing increased irritability, anxiety, and difficulty concentrating. Reducing caffeine intake during the initial phase of quitting tobacco might help mitigate these overlapping symptoms, making the withdrawal process more manageable. Additionally, being mindful of caffeine consumption can prevent exacerbating withdrawal-related insomnia and restlessness.

What role does genetics play in the susceptibility to tobacco addiction?

Genetics plays a significant role in an individual’s susceptibility to tobacco addiction. Research has identified specific genetic variations that influence how nicotine is metabolized and how the brain’s reward pathways respond to nicotine. These genetic factors can affect the intensity of nicotine cravings, withdrawal symptoms, and the overall likelihood of developing a tobacco addiction. Understanding one’s genetic predisposition can help tailor more effective prevention and treatment strategies, potentially incorporating personalized approaches to smoking cessation.

Are smokeless tobacco products safer than cigarettes?

Smokeless tobacco products still contain harmful chemicals and nicotine, which can lead to addiction and various health issues, including oral cancers and gum disease.

Can occasional tobacco use lead to addiction?

Yes, even occasional tobacco use can lead to addiction. Nicotine is highly addictive, and regular use, regardless of frequency, can result in dependence.

How does tobacco addiction affect pregnancy?

Tobacco addiction during pregnancy increases the risk of miscarriage, premature birth, low birth weight, and congenital disabilities. It can also affect the baby’s long-term health and development.

Is secondhand smoke dangerous?

Yes, secondhand smoke contains many of the same harmful chemicals as directly inhaled smoke. It can increase the risk of heart disease, lung cancer, and respiratory illnesses in nonsmokers.
