Overview

Inhaling smoke has lasting adverse impacts on human health, causing conditions such as cardiovascular diseases, cancers, and diabetes.

In any form, whether inhaled or chewed, tobacco poses serious health risks. Tobacco products are laden with harmful chemicals, including acetone, tar, nicotine, and carbon monoxide. These agents, when inhaled, can harm your respiratory system and other bodily organs. Swapping cigarettes for alternatives like cigars, e-cigarettes, pipes, or waterpipes does not mitigate the associated health dangers.

The repercussions of smoking on the body are continuous and can lead to chronic issues affecting different body systems. Smoking elevates the risk of long-term health problems over time, such as glaucoma, various cancers, and blood clotting disorders, with some immediate effects on the body.

The American Lung Association states that cigarettes contain around 600 components, which are common in cigars and hookah tobacco as well. Combustion of these substances creates over 7,000 chemicals, numerous of which are poisonous, including at least 69 that cause cancer.

In the U.S., smokers have a mortality rate three times higher than that of non-smokers. The Centers for Disease Control and Prevention (CDC) identifies smoking as the leading of preventable deaths in the country.

The consequences of smoking may not be immediate, but the harm and complications can persist for years. Fortunately, quitting smoking can diminish the risk factors significantly for the conditions and illnesses mentioned below. [1,2,3,4]

The Dangers of Smoking on Your Body

Overall Wellbeing and the Cancer Risk

Tobacco use can damage your internal organs and adversely affect your general wellness.

It can escalate inflammation in your body and compromise your immune defense, potentially heightening your vulnerability to infections.

Tobacco use is a recognized environmental contributor to conditions like rheumatoid arthritis, though the underlying reasons for this link remain unclear.

A robustly researched connection also pertains to smoking and a multitude of cancer types. Tobacco use can elevate your chances of cancer virtually throughout your body. The cancers include:

• Bladder cancer
• Acute myeloid leukemia
• Cervical cancer
• Colorectal cancer
• Esophageal cancer
• Cancers of the kidney and uterus
• Cancer of the larynx
• Liver cancer
• Cancer of the oropharynx (affecting areas like your throat, tongue, tonsils, and the soft part of the roof of your mouth)
• Pancreatic cancer
• Cancers of the stomach or gastric system
• Cancers of the trachea, bronchi, and lungs

Abandoning smoking can lead to a reduction in the risk for these cancers within approximately 10 to 20 years, with the specific timeframe depending on the cancer type. Nonetheless, your risk remains above that of individuals who have never smoked. [5,6,7]

Neurological Effects

Tobacco contains nicotine, a psychoactive substance that leads to addiction. Its addictive properties make cessation of smoking challenging.

Upon inhalation, nicotine swiftly enters the brain, initially stimulating alertness. However, as its influence diminishes, lethargy sets in, prompting further cravings. Nicotine cessation can disrupt cognitive functions and provoke adverse emotional states, such as:

• Nervousness
• Short-temperedness
• Despondency

Moreover, discontinuing it might result in cephalalgia and sleep disturbances. [8,9]

Vision

Chronic smoking may impair your eyesight and damage the optic nerve. It could precipitate the onset of specific ocular diseases, such as:

• Glaucoma, where eye pressure escalates, exerting stress on the optic nerve, leading to harm and vision loss.
• Cataracts, leading to vision becoming blurred.
• Age-related macular degeneration, damaging the retina's central point and resulting in the deterioration of your central eyesight. [10]

Lung Health

Inhalation of tobacco smoke harms the bronchial passages, delicate lung structures (alveoli), and the cilia, which are minuscule, hair-like entities that block dust and phlegm from the lungs.

Pulmonary Injury

Tobacco use inflicts irreversible pulmonary injury and loss of lung tissue.

Injuries to the lungs can heighten vulnerability to certain lung infections, including tuberculosis and pneumonia, and amplify the risk of mortality from these diseases.

Tobacco use may lead to persistent coughing and, for individuals with asthma, escalate the severity of asthma episodes. [11]

Cancer Threat

Lung harm due to tobacco may result in lung disorders or lung carcinoma. Tobacco usage is the primary lung cancer culprit, with smokers at a 20-fold greater risk of lung cancer compared to non-smokers. [12]

Chronic Pulmonary Conditions

Smokers are more susceptible to enduring, nonreversible pulmonary issues, such as:

• Emphysema, which destroys lung air sacs.
• Chronic bronchitis, which is continual swelling affecting the lung's air passages.
• Chronic obstructive pulmonary disease (COPD), comprising various lung conditions.
• Lung carcinoma.
• Asthma beginning in adulthood.

Cessation from smoking can lead to temporary blockage and pulmonary distress as healing commences in the lungs and airways. Post-quitting increases in phlegm is a sign of pulmonary recovery. [13]

Youth and Adolescents

Infants may suffer from incomplete lung development if the mother smoked during pregnancy.

Youths exposed to tobacco smoke by parents or guardians face an elevated risk of health issues compared to those unexposed. These health concerns include:

• Persistent coughing
• Breathlessness
• Asthma exacerbations
• Pneumonia
• Tuberculosis
• Bronchial inflammation
• Diminished lung capacity
• Stunted lung growth
• Cryptogenic fibrosing alveolitis

Adolescents who engage in smoking may have smaller, less robust lungs than their non-smoking peers. [14,15]

Reproductive Health and Sexuality

Nicotine impedes genital blood circulation in both women and men.

Impacts on Fertility

Additionally, smoking can cause fertility challenges and diminish sex hormones in both genders, potentially reducing sexual appetite. [16]

In Females

In females, smoking can impair sexual gratification by reducing lubrication and orgasmic capability. It’s also linked to an earlier onset of menopause in smokers compared to non-smokers.

Smoking affects hormone levels and may complicate pregnancy in females. It's associated with a higher risk of:

• Preterm birth
• Babies with lower weights
• Stillbirths
• Sudden infant death syndrome (SIDS)
• Pregnancies outside the uterus
• Newborns with cleft conditions [17]

In Males

In males, smoking can impair sexual functionality.

Tobacco use can adversely impact vascular function, potentially limiting penile blood flow essential for an erection. This restriction can cause erectile dysfunction (ED), which may also affect fertility.

Moreover, it can harm sperm DNA, complicating conception efforts and heightening the risk of miscarriage and specific congenital anomalies. [18]

Cardiovascular Health

The CDC states that 25% of U.S. fatalities are due to heart-related conditions linked to tobacco use.

The components of the circulatory system that smoking harms include:

• The heart
• Arteries
• Blood channels

Nicotine narrows blood pathways, hindering circulation. Additionally, smoking elevates blood pressure, compromises the integrity of vascular walls, and heightens the likelihood of clot formation.

Such effects amplify the threat of circulatory diseases, such as:

• Plaque buildup in arteries
• Cardiac conditions leading to heart attacks or unexpected heart failures
• Cerebral vascular incidents
• Diseases in the peripheral arteries
• Enlargement of the major abdominal artery

If you have a history of heart-related surgeries or conditions, smoking raises the chances of further complications.

Effects of Passive Smoking

Not only does smoking affect your heart health, but it also poses similar dangers to non-smokers through secondhand smoke exposure. Non-smokers exposed to environmental tobacco smoke face comparable risks of:

• Cerebral vascular incidents
• Myocardial infarctions
• Coronary diseases [20]

Cutaneous System (Skin, Hair, and Nails)

The habit of smoking cigarettes may impact your cutaneous system.

Skin

The constituents of cigarette smoke may alter your skin's architecture. This alteration can lead to:

• Accelerated skin degradation resembling premature aging
• The development of wrinkles
• Slower healing of wounds
• The occurrence of hidradenitis suppurativa, a condition leading to agonizing boils
• The onset of psoriasis or exacerbation of existing psoriasis
• An increased likelihood of certain skin cancers

The act of smoking heightens the chances of incurring squamous cell carcinoma (skin cancer) on the lips. [21,22]

Hair

Evidence suggests a connection between smoking and the occurrence of androgenic alopecia, which results in hair thinning in men. Smoking prompts hair thinning because of:

• Restricted blood flow
• Damage to DNA
• The creation of oxidative free radicals
• Impacts on hormones [23]

Nails

Your fingernails and toenails might be adversely affected by smoking, boosting the probability of fungal nail infections. [24]

Gastrointestinal Tract

The gastrointestinal tract is notably impacted by cigarette smoke.

Oncological Concerns

The likelihood of developing cancers within the digestive tract is heightened by smoking. Potential cancers include those of the:

• Oral cavity
• Pharynx
• Voice box
• Esophagus
• Gastric region
• Pancreas
• Large intestine and rectum

Non-inhalers who smoke are also at a heightened risk for oral cancer. [25]

Diabetes

The interaction of smoking with insulin can lead to an increased chance of insulin resistance. Smokers are at a 30% to 40% increased risk of acquiring type 2 diabetes and its related health issues.

In smokers, type 2 diabetes may progress more rapidly than in non-smokers and is more challenging to manage.

For more information, check our full guide on Diabetes. [26]

Gum Diseases

The risk for gum disease, also known as periodontal disease, escalates with smoking because it promotes inflammation around the teeth and elevates bacterial infection risks. Symptoms include swollen, bleeding gums (gingivitis) and the eventual recession of gums from the teeth (periodontitis). [27]

Skeletal System

The use of tobacco can detrimentally affect your skeletal integrity by lowering bone density and fostering the loss of bone.

The habit of smoking is associated with the risk of developing ailments such as osteoporosis or the increased incidence of bone breaks. Additionally, smoking can adversely influence the recovery process of bones following a fracture.

In women, the act of smoking might induce an earlier onset of menopause. The acceleration of bone depletion is a consequence of menopause. When combined with smoking, these impacts could be intensified, potentially leading to osteoporosis.

Moreover, smoking can compromise your dental health and is linked to the deterioration and subsequent loss of teeth. [28,29,30]

What Happens After You Quit Smoking?

Quitting smoking, regardless of how long you've indulged, can mitigate the detrimental impacts of tobacco and you'll notice health improvements from the initial few hours to many years post-quitting.

Inhaling smoke bombards your body with myriad chemicals. This assault harms not just the lungs but also affects the heart and other bodily structures significantly.

Outlined here are numerous health benefits you may observe upon deciding to quit smoking this very day.

What Occurs Within Your Body When You Halt Smoking Abruptly?

The advantageous health changes from stopping smoking commence 20 minutes following your final cigarette. Your blood pressure and heartbeat commence reverting to their normal rates.

Moreover, the bronchial tubes' fibers, which were impaired by continuous smoke exposure, begin to function effectively once more. This change aids your lungs: These fibers are crucial in expelling irritants and bacteria from the lungs, thereby diminishing infection risks.

Eight Hours After Your Last Cigarette

After a span of eight hours of abstaining from cigarettes, the carbon monoxide concentration in your bloodstream diminishes to a healthier measure. This harmful compound, found abundantly in cigarette smoke, usurps the place of oxygen molecules within your blood, thereby reducing the oxygen available to your body's tissues.

As the carbon monoxide level declines, the oxygen in your blood begins to rise back to typical levels. This surge in oxygen provision revitalizes the tissues and blood vessels that had been deprived of adequate oxygen during the time you smoked.

Following A Full Day Without Cigarettes

Once you've reached the 24-hour point, your bloodstream's nicotine content diminishes to an almost undetectable level.

At this juncture, the lessening of tightness in your blood vessels, coupled with a rise in oxygen supply to the heart, enhances your heart's performance. This reduction in arterial constriction lowers your risk of experiencing a heart attack.

At The Two-Day Mark Without Cigarettes

In two days, the regeneration of damaged nerves begins. An improvement in senses that were impaired by smoking may become apparent. You might discover an enhanced ability to smell and taste compared to your previous experiences.

72 Hours Post-Smoking Cessation

By the time you hit the 72-hour mark of having quit smoking, it’s typical to experience improved respiration. This improvement comes as the bronchial passages within your lungs begin to dilate and expand. Consequently, this expansion facilitates a more efficient transfer of oxygen and carbon dioxide.

Moreover, roughly three days after you stop smoking, there’s an increase in lung capacity, which refers to the volume of air the lungs can hold.

Following A Week-Long Cessation from Tobacco

Post seven days of abstinence, the carbon monoxide concentration in your bloodstream reverts to typical levels.

Bear in mind, the probability of permanently abstaining from smoking rises with each trial. Survive a week, and you're set for an enduring smoke-free life.

Within A Fortnight of Ceasing to Smoke

In as little as two weeks after you've stopped smoking, it might become apparent that your breathing has become more effortless. Walking may also seem less challenging. Enhanced blood flow and oxygen levels contribute to this improvement.

Approximately two weeks post-smoking cessation, the American Lung Association states that lung capacity can rise by up to 30%.

One Month into Quitting Smoking

A mere thirty days sans cigarettes can yield numerous health improvements from ceasing smoking. Among these is an enhanced feeling of increased vitality overall.

Furthermore, you might observe a reduction in many symptoms associated with smoking, like nasal blockage and the struggle to breathe during physical activity.

Alongside these advantages, regenerative lung fibers that contribute to lung health start to reemerge. Such fibers assist in minimizing the accumulation of surplus phlegm and in shielding against infections caused by bacteria.

Ultimately, individuals who succeed in abstaining from smoking for a full month are quintuple as likely to cease permanently.

Three Months Post Cessation of Smoking

In a span of three months following smoking cessation, a female can enhance her chances of fertility and diminish the likelihood of experiencing a preterm birth of her child.

Six Months into Cessation

Half a year post-quitting, individuals typically observe an enhanced ability to manage stress without craving cigarettes.

They’ll likely also experience a significant reduction in coughing up mucus and phlegm, as their airways are no longer persistently irritated by the smoke and various substances in cigarettes. Consequently, engaging in exercise, such as walking, becomes less challenging.

One Year into Cessation

A year into your smoke-free journey, your lung health will have significantly improved in both capacity and performance. You'll observe a marked ease in breathing during physical activity and a notable decrease in coughing relative to your smoking days.

Beyond these health gains, the economic savings are substantial. The cost of smoking is steep. A daily habit of one cigarette pack could have amounted to a saving of thousands after twelve months.

Three Years into Cessation of Smoking

Upon reaching the three-year mark of smoking cessation, your risk of cardiac disease is reduced by 50%.

Smoking restricts oxygen delivery to the cardiac muscles and harms the arterial walls. This leads to an accumulation of lipids, increasing the risk of myocardial infarction or cerebrovascular accident. Abandoning the smoking habit can mitigate these risks, fostering cardiac wellness over subsequent years.

Five Years Post-Quitting Smoking

Half a decade of abstaining from smoking diminishes your stroke risk to equal a person who's never smoked. The likelihood of developing cancer in the mouth, throat, or larynx is cut by 50%.

A Decade into Smoking Cessation

Upon reaching ten years smoke-free, lung cancer risk is cut by 50%.

Moreover, the likelihood of contracting illnesses linked to smoking lessens. This encompasses a diminished risk for cancers affecting the:

• Oral cavity
• Esophagus
• Urinary bladder
• Renal system
• Pancreatic region

Upon Reaching 15 Smokeless Years

When you hit the 15-year threshold, your risk of a heart attack drops to match someone who has never indulged in smoking. Although reversing the impact of smoking may be a lengthy process, completing a decade and a half without cigarettes signifies a significant triumph for your health and wellness.

Inquiring About Smoking Cessation?

As people increasingly strive to cease smoking, there has been a corresponding surge in the variety of cessation aids and programs. By consulting with a healthcare provider, you can identify an effective cessation strategy that may incorporate multiple aids.

You vowed to stop smoking post-college, at 30, or when your first child arrived. You assured your loved ones you’d quit after settling into your new job, discovering the right program, or upon retirement.

Annually, numerous Americans commit to themselves and their families to stop smoking permanently. Countless individuals achieve this goal each year. You could join their ranks.

Nicotine Replacement Therapy

Nicotine replacement therapy (NRT) provides the nicotine your body craves in a form that's safer than smoking. You gradually lower the nicotine levels you use with the goal of entirely eliminating your dependence. Forms of this therapy include:

• Skin patches
• Chewing gum
• Nasal sprays [31]

Medications For Quitting Smoking

Medicines like Chantix or Zyban adjust your brain's chemistry to help reduce cravings and symptoms of withdrawal.

Several of these drugs permit the simultaneous use of nicotine substitutes like patches or gum to mitigate intense symptoms of withdrawal. A few allow you to keep smoking as you start the regimen, aligning with your predetermined cessation date. [32,33]

Complementary Treatments

The subsequent treatments target both psychological and bodily routines, like stress control, diminishing urges, and additional obstacles associated with tobacco use.

There is not enough proven research to demonstrate that these complementary treatments surpass other behavioral interventions or self-directed cessation efforts in terms of effectiveness for quitting smoking. The treatments encompass:

• Hypnotherapy
• Acupressure
• Mindfulness practices

Individuals abandoning smoking may employ these treatments independently, or alongside pharmacotherapy or nicotine replacement strategies. [34,35,36]

Support

Support strategies encompass therapy sessions and support groups for cessation of smoking. Numerous physicians and experts on quitting smoking advocate for these techniques alongside pharmacological or reduced-nicotine solutions.

If you’re a smoker, you’re likely aware of the harm your practice inflicts on your health. Such damage entails:

• Decreased life expectancy
• Heightened probability of developing cancer
• Accelerated aging

Chances are, you've observed at least one individual who smokes lifelong succumbing to smoking-associated illnesses, for instance:

• Lung carcinoma
• Cardiovascular conditions
• Cerebrovascular problems

Likely, you can enumerate the obstacles you face while attempting to abandon smoking. These may consist of:

• Recurrence
• Increase in body weight
• Symptoms of cessation

Every smoker's path is unique. With each victory comes a fresh challenge, and every achievement — a week, a month, a year without a cigarette — brings immense happiness to you and your loved ones. Ultimately, the choice to cease smoking is personal, yet the quest need not be solitary. [37]

More Tips for Quitting Smoking

Steer Clear of Temptations

Cravings for a smoke often hit hardest in spots where you used to light up regularly, like during outings or while unwinding with a coffee. Pinpoint your trigger scenarios and strategize to sidestep them or push through sans tobacco.

Don't pave the path to a smoke relapse. If a cigarette was your go-to during phone chats, have a pen and notepad at hand for scribbling to keep your hands busy.

Postpone

Feeling on the verge of caving to a smoke yearning? Promise yourself a 10-minute delay. Meanwhile, engage in a diversion. Head to a place where smoking is off-limits. Often, this small act of procrastination can help you dodge the craving.

Keep Your Mouth Occupied

When the urge to smoke strikes, keep your mouth busy. Chew on sugar-free gum or suck on hard candy. Crunch on something satisfying like raw veggies, nuts, or sunflower seeds.

Resist the 'Only One'

It's tempting to quell a tobacco urge with just a single cigarette. But tricking yourself into believing it stops there is risky. Usually, one leads to another, and you might find yourself back in the tobacco trap.

Get Moving

Physical activity can shift your focus from tobacco urges. Quick, intense exercise bouts, like several stair runs, can squelch the craving. Head out for some fresh air with a brisk walk or jog.

Stuck indoors? Do squats, knee bends, push-ups, jog on the spot, or take to the stairs. If exercise isn't your thing, turn to prayer, knitting, carpentry, journaling, or housework—anything that keeps you preoccupied.

Embrace Relaxation

If smoking was your stress relief, confronting a craving can be taxing. Ease stress with relaxation practices: deep-breathing, progressive muscle relaxation, yoga, visualization, a soothing massage, or calming tunes.

Seek Backup

Reach out to someone in your circle or a support buddy when you're grappling with a craving. Have a chat, take a stroll, share a laugh, or get together for mutual encouragement. Consider counseling, too. For Americans, the toll-free quit line — 800-QUIT-NOW (800-784-8669) — offers support and guidance.

Find Support Online

Dive into an online quitting program. Browse blogs of others who've quit and cheer them on. Glean insights on handling cravings from their experiences.

Remember Why You're Quitting

Jot down or voice your reasons for quitting and fighting off cravings. These might be to feel better, become healthier, protect your family from secondhand smoke, or save cash. Taking any action against the tobacco urge trumps inaction every time. And each resisted craving is a step toward a tobacco-free life.

Managing a Smoking Setback

Halting the smoking habit is often an arduous journey. Multiple trials might be necessary to accomplish your objective. Stress, increased weight, and nicotine or tobacco withdrawal signs are typical relapse triggers.

Fortunately, strategies exist to deal with smoking setbacks effectively. “Slip-ups” can happen within the initial days, over several months, or years post your quitting decision. Though these sudden cravings can be risky, methods to handle them are available.

I Messed Up, What Now?

It's common to stumble in the initial week of quitting smoking. A puff or even a full relapse doesn't spell failure; you can always restart your journey to quit. Keep in mind that you hold the reins and can continue to work towards a smoke-free life.

Plus, you're in good company. Each year, about 70% of adult smokers desire to kick the habit for good. Throughout the year, countless individuals attempt to quit, trying everything from medical treatments and counseling to nicotine substitutes and other alternative strategies.

A single mistake might bring about guilt, sadness, or harsh self-judgment. These feelings can spiral into despair and a loss of motivation. Multiple mistakes may lead to a complete backslide, yet it's never too late to try again. Confronted with the urge to smoke, don't trick yourself into thinking one cigarette is harmless. Focus instead on the myriad of health gains quitting smoking brings.

Slip-up Sparks

Sudden cravings to light up are treacherous and can lead you to slip back into smoking. A mix of triggers - specific situations or emotions - can conspire to derail your smoke-free journey. Recognizing and steering clear of these triggers is key.

Frequent slip-up sparks include:

• Hanging out with smokers, particularly when relaxing
• Drinking alcohol
• Feeling overly confident in your ability to resist smoking
• Drifting away from friends, family, and your support network
• Skimping on sleep or relaxation
• Regularly encountering stressful scenarios
• Feeling victimized, along with surges of anger and self-pity
• Sinking into a negative, defeatist mindset

Dodging as many triggers as you can substantially boosts your odds of quitting for good. Although it's tough to sidestep every trigger, preparing for them can tilt the odds in your favor.

Stress is a major smoking spark, but it's one you can significantly dial down. Managing stress bolsters your quit attempt, before and amid stress. Embracing stress-relief strategies like working out, taking strolls, soaking in a hot bath, or practicing meditation can slash stress-induced cravings.

Having a solid support circle is invaluable during a relapse or hiccup. Remember, it's crucial to not beat yourself up over setbacks, but to press on and stay determined.

Keep Pushing Forward

If you've slipped up once or a hundred times, don't throw in the towel on your journey to stop smoking. It's common for people to make multiple attempts before they triumph. View any relapse as a lesson and an experience to draw on later. Every effort you make to quit brings you one step nearer to your goal.

Having people around who cheer you on can make a world of difference when you're working to quit. People who've successfully quit often say that having the support of family, friends, and colleagues was crucial. If your personal network is small, don't worry—your doctor and healthcare team are there to back you up and cheer you on.

Support groups can offer timely encouragement and help you find your footing again if you've stumbled or had a setback. You can find tobacco cessation resources through your health insurance, local medical centers, and even your workplace. They typically provide a helpline or a website full of information and support to help you quit smoking.

Conclusion

Quitting smoking is a challenging but achievable goal. It's important to understand the serious health risks associated with smoking and to be prepared for the challenges of quitting, such as dealing with cravings and the potential for relapse. A variety of aids, including nicotine replacement, medications, and complementary therapies, can help in this process, and support from healthcare providers and peers is invaluable. While relapses can occur, they should be seen as part of the journey rather than the end of it. Persistence and support are key to ultimately quitting successfully.
