Names & Terms You Will Hear
Plain-language meanings for the terms your care team may use.
| Term | Meaning |
|---|---|
| Cigarette Smoking | Burning tobacco and breathing in the smoke. The biggest preventable cause of heart disease and early death. |
| Tobacco Use | Any product made from tobacco - cigarettes, cigars, pipes, chew, snuff, hookah. All raise heart risk. |
| Nicotine | The drug in tobacco that causes addiction. It also narrows blood vessels and raises blood pressure and heart rate. |
| Vaping (E-Cigarette) | A battery-powered device that heats nicotine and flavored liquid into a mist. Not water vapor - and not a safe substitute for cigarettes. |
| EVALI | E-cigarette or Vaping product-use Associated Lung Injury. A serious lung illness first reported in 2019, often linked to vitamin-E acetate in THC vapes. |
| Cannabis / Marijuana | Smoked or vaped cannabis (THC) speeds up the heart and can trigger heart attacks - especially in the first hour after use. |
| Secondhand Smoke | The smoke you breathe in from someone else's cigarette. Raises your heart-disease risk by about 25 to 30 percent even if you do not smoke. |
| Thirdhand Smoke | The smoke residue that sticks to clothing, furniture, walls, and cars. Children and infants are most affected. |
| Smoking Cessation | The medical term for quitting smoking. Includes counseling, medication, and follow-up - not just willpower. |
| NRT (Nicotine Replacement Therapy) | Patches, gum, lozenges, inhalers, and nasal sprays that give you controlled nicotine without the smoke. |
| Varenicline (Chantix) | A prescription pill that blocks nicotine's effect in the brain. The single most effective stop-smoking medicine. |
| Bupropion SR (Zyban / Wellbutrin SR) | A prescription pill that helps with quitting and with depression. Lowers seizure threshold. |
| Quitline (1-800-QUIT-NOW) | A free national phone-coaching service for quitting smoking. Florida residents can also call 1-877-U-CAN-NOW. |
1. Smokers have 2 to 4 times the risk of coronary heart disease.
2. Within 1 year of quitting, that risk is cut in HALF.
3. Within 15 years, it matches a person who never smoked.
What Is Smoking and the Heart?
- Smoking is the inhaling of smoke from burning tobacco. It is the single largest preventable cause of heart disease, stroke, lung disease, and early death in the United States.
- Tobacco smoke contains over 7,000 chemicals. About 70 of them cause cancer. Many more damage the heart and blood vessels directly.
- Nicotine is the drug that keeps people smoking. It narrows your arteries, raises your blood pressure, and speeds up your heart - putting extra strain on the heart muscle.
- Carbon monoxide is the second main problem. It binds to red blood cells in place of oxygen, so your blood carries LESS oxygen to your heart, brain, and muscles.
- Tobacco use is not limited to cigarettes. Cigars, pipes, hookah, smokeless tobacco (chew, snuff), e-cigarettes (vaping), and smoked cannabis all raise heart and blood-vessel risk.
- Quitting is the single most powerful thing you can do for your heart. It works at any age, and it works even if you have already had a heart attack or stent.
- Quitting is also one of the hardest things you will ever do. It almost always takes more than one try. Counseling plus medication doubles or triples your chance of success vs. willpower alone.
Why It Matters
- Smokers have 2 to 4 times the risk of coronary heart disease compared with non-smokers.
- Smokers have about a 70 percent higher risk of stroke than non-smokers.
- Smoking raises the risk of sudden cardiac death by 2 to 3 times. It is the single most common preventable cause of heart attack in young and middle-aged adults.
- Smoking is a leading cause of peripheral artery disease (PAD) - narrowed arteries in the legs - and of abdominal aortic aneurysm.
- Even light smoking (1-4 cigarettes per day) nearly triples the risk of heart attack. There is no safe level of smoking.
- Within 1 year of quitting, your risk of coronary heart disease falls by HALF.
- Within 5 years your stroke risk falls back to that of a person who never smoked.
- Within 15 years your coronary heart disease risk is the same as a non-smoker.
- Smoking cessation is a Class I recommendation in every major prevention guideline (ACC/AHA, ESC). It is the highest-impact lifestyle change in cardiology.
- If you have already had a heart attack or stent, quitting cuts your risk of a second heart attack or death by about a THIRD.
Risk Factors
Knowing your personal risks helps your care team take extra precautions.
| Risk Factor | Why It Increases Risk |
|---|---|
| Years smoked and packs per day | Risk goes up with both. Pack-years (packs per day x years smoked) predict heart attack, stroke, and lung-cancer risk. |
| Age you started | Starting before age 15 causes more lifelong damage to arteries than starting in adulthood. |
| Female sex on hormonal contraception | Smoking plus the birth-control pill raises the risk of heart attack, stroke, and blood clots much more than either alone - especially over age 35. |
| Already-known heart disease | If you have CAD, a prior heart attack, a stent, or a bypass, smoking doubles your risk of a second event. Quitting is urgent. |
| High blood pressure or diabetes | Smoking multiplies the damage from these conditions. The combination is much worse than the sum of the parts. |
| Family or roommate smokes | Living with a smoker is a strong predictor of relapse after quitting. Quitting together works better than quitting alone. |
| Mental-health conditions | Depression, anxiety, schizophrenia, and PTSD all raise smoking rates and make quitting harder. Cessation medication is safe in these patients (EAGLES trial). |
| Vaping or cannabis use | Daily vaping or cannabis use exposes the heart and blood vessels to many of the same harmful effects as smoking. |
Treatment Options
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
- Set a quit date within the next 2 weeks. Tell your family, friends, and coworkers. Throw out cigarettes, lighters, and ashtrays the night before.
- Combine medication with counseling. The two together work much better than either alone. Most insurance plans cover both at no out-of-pocket cost.
- Varenicline (Chantix) is the most effective single medicine. It blocks nicotine's reward in the brain. Start 1 week BEFORE your quit date. Take for 12 weeks (longer if needed). Side effects: nausea, vivid dreams. The EAGLES trial showed it does NOT raise mental-health side effects.
- Nicotine Replacement Therapy (NRT) gives you controlled, lower-dose nicotine without smoke. Combination NRT (a 24-hour patch PLUS short-acting gum or lozenge for cravings) works best. Patches: 21 mg / 14 mg / 7 mg, stepped down over 8-12 weeks. Gum and lozenges: 2 mg or 4 mg as needed.
- Bupropion SR (Zyban / Wellbutrin SR) 150 mg twice a day. Start 1-2 weeks BEFORE your quit date. Helps with cravings and depression. Avoid if you have seizures or an eating disorder.
- Combination therapy - varenicline + NRT, or bupropion + NRT - is even more effective than any single drug. Ask your doctor.
- Behavioral counseling - phone, in-person, or text-based - doubles your quit rate. Free options include 1-800-QUIT-NOW (national), Florida Quit Your Way at 1-877-U-CAN-NOW, the AHA "Quit With" guide, and the smokefree.gov text and app programs.
- Cardiac rehab includes a structured tobacco-cessation program. If you have had a heart attack, stent, bypass, or new heart-failure diagnosis, ask us for a referral.
- What to expect: the first 1-2 weeks are the hardest. Cravings come in waves of 3-5 minutes. Sleep, mood, and appetite changes are normal and improve by week 4. Most relapses happen in the first 3 months - keep your medication going through that window.
- Most people need more than one quit attempt. Each try teaches you what works and what does not. Coming back to your doctor after a slip is a strength, not a failure.
Quit-Smoking Medicines at a Glance
| Medicine | How well it works | Common side effects | Best for |
|---|---|---|---|
| Varenicline (Chantix), 12 weeks | Most effective single medicine. Roughly TRIPLES quit rate vs. willpower alone (EAGLES). | Nausea, vivid dreams. Mood changes are uncommon (no excess vs placebo in EAGLES). | Heavy smokers, prior failed quit attempts, patients without seizure or pregnancy concerns. |
| Combination NRT (patch + gum or lozenge), 8-12 weeks | DOUBLES quit rate. Patch gives steady level; gum or lozenge treats break-through cravings. | Skin irritation from patch, jaw soreness or hiccups from gum, vivid dreams (remove patch at night if needed). | Almost anyone. Available over-the-counter. Safe in stable heart disease. |
| Bupropion SR (Zyban / Wellbutrin SR), 7-12 weeks | DOUBLES quit rate. Adds antidepressant benefit. | Dry mouth, insomnia, mild BP rise. Rare seizures (avoid if history of seizure or eating disorder). | Patients with depression or seasonal mood symptoms; those who want to limit weight gain. |
| Combination therapy (varenicline + NRT, or bupropion + NRT) | Higher quit rates than any single drug. Reserved for difficult cases. | Side effects of both drugs combined. Watch BP and mood. | Heavy smokers who failed single-drug quit attempts. |
| Counseling only (quitline, app, group) | Doubles quit rate compared with no help. Even more powerful when added to medication. | None. Time commitment only. | Anyone. Always recommended in addition to medication. |
Medication + counseling + a quit date. Pick a date in the next 2 weeks. Start varenicline OR combination NRT a week before. Sign up for free coaching at 1-877-U-CAN-NOW (Florida) or 1-800-QUIT-NOW. Tell your family. Throw out cigarettes the night before. Show up to your first cigarette-free day with a plan for cravings: 4 Ds, water, walk, call a friend.
Comfort Measures at Home (No Medication Needed)
These simple steps support healing and ease symptoms. Use them alongside any medication your doctor prescribes.
- Use the 4 Ds when a craving hits: Delay 5 minutes (the craving will pass), Drink water, Deep breaths (in for 4, out for 6), Do something with your hands.
- Identify your triggers. Morning coffee, after meals, driving, alcohol, stress, and seeing other smokers are the top five. Plan a non-smoking response for each.
- Avoid alcohol for the first 2-4 weeks. Alcohol lowers your guard and is the single biggest cause of a slip back to smoking.
- Move your body. A 10-minute walk cuts a craving in half and improves mood. Exercise is also one of the few things that limits the weight gain that can come with quitting.
- Eat regular meals. Hunger feels like a craving. Keep healthy snacks - carrots, apples, almonds - on hand. Drink water through the day.
- Get good sleep. Poor sleep makes cravings worse. Cut caffeine after lunch. Many people sleep BETTER once nicotine is out of their system.
- Tell people what you need. Ask family not to smoke around you. Ask your boss for a short walk break instead of a smoke break. Most people will help.
- Use a quit app or text program. Smokefree.gov, QuitGuide, and quitSTART are free. Florida Quit Your Way also offers text coaching.
- Reward yourself. Put the money you would have spent on cigarettes into a jar. After 1 month, buy something nice. At a pack a day, that is over $250 in 1 month and $3,000 in a year.
- Plan for weight. The average smoker gains 5-10 pounds after quitting. Even at that weight, your heart benefit is far larger than the small risk from the weight gain. Walking and a Mediterranean-style plate limit it.
Risks, Benefits, and Alternatives
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
Every choice has trade-offs. Use this table to start the shared decision conversation with your care team.
| Option | Risks | Benefits | Alternatives |
|---|---|---|---|
| Quit smoking (any method) | Withdrawal: irritability, cravings, poor sleep, hunger, low mood for 1-4 weeks. Weight gain of 5-10 lb on average. | Within 1 year, coronary heart disease risk cut in half. Within 5 years, stroke risk back to non-smoker. Lower BP, better lung function, taste, and smell within weeks. | Continuing to smoke - 2 to 4 times higher heart-attack and stroke risk; shorter life expectancy by 10 years on average. |
| Varenicline (Chantix) | Nausea, vivid dreams, sleep changes. Rare mood changes (EAGLES trial: no excess vs placebo). Costs about $300/month without insurance; covered by most plans. | The single most effective stop-smoking medicine. Roughly triples the quit rate vs. willpower alone. | NRT, bupropion, combination NRT, behavioral-only. |
| Combination NRT (patch + gum or lozenge) | Skin irritation from the patch. Hiccups or jaw soreness from gum. Vivid dreams if patch worn overnight. | Doubles the quit rate vs. willpower alone. Available over-the-counter. Safe in patients with stable heart disease. | Single-product NRT (less effective). Varenicline (more effective single agent). |
| Bupropion SR (Zyban / Wellbutrin SR) | Dry mouth, insomnia, headache. Rare seizures (avoid if seizure or eating-disorder history). May raise blood pressure - check after 2 weeks. | Doubles the quit rate. Also helps depression, so a good fit for patients with mood symptoms. | Varenicline, NRT, combination therapy. |
| Switch to vaping / e-cigarettes | Vaping is NOT a safe substitute. Nicotine still raises BP, heart rate, and clot risk. Long-term lung effects (including EVALI) are still being studied. Many "switchers" end up using both products. | May help some adult smokers cut down or quit when other methods have failed - under medical guidance only. Not FDA-approved as a cessation tool. | FDA-approved medicines (varenicline, NRT, bupropion) and counseling - more effective and safer. |
Common Misconceptions
| Myth | Reality |
|---|---|
| "Vaping is safe - it is just water vapor." | Vaping is NOT water vapor. The aerosol contains nicotine, fine particles, metals, and chemicals from flavorings. Nicotine still narrows arteries and raises blood pressure. EVALI (vaping-related lung injury) put thousands in the hospital. Vaping is not FDA-approved as a quit aid. |
| "Light or low-tar cigarettes are safer." | They are not. Smokers of "light" cigarettes inhale deeper or smoke more of them, ending up with the same exposure. The FDA banned the term "light" in 2010 for this reason. |
| "You have to quit cold turkey - medicines are cheating." | Cold turkey works for fewer than 1 in 20 people on the first try. Medicines plus counseling double or triple the quit rate. Asking for help is the smart play, not cheating. |
| "The damage is already done - why bother quitting now?" | Wrong. Within 1 year of quitting, coronary heart disease risk drops by HALF. Within 5 years, stroke risk is back to non-smoker. Quitting helps at every age - even after a heart attack or stent. |
| "Quitting will make me gain weight and that is worse for my heart." | The average weight gain after quitting is 5-10 pounds. Even with that gain, the heart benefit of quitting is far larger than the small risk of the weight. The math is clear: quit first, manage weight second. |
| "Cannabis is natural, so it does not hurt the heart." | Smoked or vaped cannabis (THC) speeds up the heart, raises blood pressure, and can trigger a heart attack - especially within 1 hour of use. Cannabis arteritis is a rare but real complication. "Natural" does not mean safe for the heart. |
| "Secondhand smoke is just unpleasant, not dangerous." | Non-smokers exposed to secondhand smoke at home or work have a 25-30 percent higher risk of coronary heart disease. Children of smokers have more asthma, ear infections, and sudden infant death. There is no safe level of secondhand smoke. |
| "Hookah and cigars are safer because you do not inhale as much." | An hour of hookah delivers roughly the smoke of 100 cigarettes. Cigars and pipes still cause mouth, throat, and esophageal cancers and raise heart and stroke risk. |
Possible Complications
Knowing what can go wrong helps you spot problems early. Most complications are uncommon, especially with treatment.
| Where / What | What Can Happen |
|---|---|
| Coronary artery disease (CAD) | Smoking accelerates plaque buildup in the heart arteries. Smokers develop CAD 10 years earlier on average than non-smokers. |
| Heart attack | Tobacco doubles or quadruples the risk of acute coronary syndromes. It is the most common preventable cause of heart attack in young adults. |
| Stroke | Smokers have about 70 percent higher stroke risk. Includes both clot-type and bleeding-type strokes. |
| Sudden cardiac death | Smoking raises the risk of sudden cardiac arrest by 2 to 3 times - in part from arrhythmias triggered by nicotine and ischemia. |
| Peripheral artery disease (PAD) | Smoking is the strongest risk factor for narrowing of the leg arteries. Symptoms include leg pain with walking, slow-healing wounds, and amputation in advanced cases. |
| Abdominal aortic aneurysm | Smokers have 3-5 times the risk of an aneurysm - a weak, ballooning section of the main artery in the belly that can rupture. |
| Heart failure | Smoking damages the heart muscle through high BP, repeated heart attacks, and direct toxic effects. Worsens both HFrEF and HFpEF. |
| Lung disease (COPD) | Emphysema and chronic bronchitis lower oxygen levels and put extra strain on the right side of the heart. |
| Cancer | Smoking causes cancer of the lung, mouth, throat, esophagus, bladder, kidney, pancreas, stomach, colon, cervix, and blood (leukemia). |
| Pregnancy and infant complications | Smoking during pregnancy raises the risk of preterm birth, low birth weight, stillbirth, and sudden infant death (SIDS). |
Vaping and E-Cigarettes - Not a Safe Alternative
- What vaping is: a battery-powered device heats a liquid into an aerosol you breathe in. The liquid contains nicotine, propylene glycol or glycerin, and flavoring chemicals. It is NOT water vapor.
- Nicotine still hurts your heart. Vape nicotine narrows arteries, raises blood pressure and heart rate, and makes blood stickier - the same mechanisms as cigarette smoke.
- The aerosol carries more than nicotine. Fine particles, metals (nickel, tin, lead), and flavoring chemicals reach the lungs and the bloodstream. Long-term cardiovascular effects are still being studied.
- EVALI (vaping lung injury): in 2019, thousands were hospitalized and dozens died from a vaping-related lung illness, mostly linked to vitamin-E acetate in THC vape cartridges. Less common now, but still reported.
- Vaping is NOT FDA-approved as a quit-smoking tool. Many adults who switch end up using BOTH cigarettes and vapes (dual use), which is worse than either alone.
- Youth vaping: nicotine harms the developing teen brain, raises the lifetime risk of addiction, and is a known gateway to cigarettes. Most adolescent vapers did not smoke before.
Cannabis (Marijuana) and the Heart
- THC speeds up the heart. Within minutes of smoking or vaping cannabis, heart rate rises by 20-50 percent and blood pressure goes up. These effects last 2-3 hours.
- 1-hour heart-attack window: the risk of having a heart attack is about 4-5 times higher in the first HOUR after smoking cannabis. Risk returns to baseline after a few hours.
- Cannabis arteritis: a rare but serious narrowing of leg or arm arteries seen in heavy young cannabis users. Similar to Buerger disease seen with cigarettes.
- Atrial fibrillation and other arrhythmias have been reported with both smoked and edible cannabis - especially with high-THC products.
- If you have CAD, prior heart attack, heart failure, or arrhythmia, talk to us BEFORE using cannabis - smoked, vaped, or edible. "Natural" does not mean safe for your heart.
- Edibles are not heart-safe either. Late-onset effects (1-2 hours after eating) can be very strong and unpredictable.
Secondhand and Thirdhand Smoke - Why a Smoke-Free Home Matters
- Secondhand smoke is the smoke breathed out by a smoker and the smoke from the burning end of a cigarette. There is no safe level of exposure.
- Heart-disease risk goes up 25 to 30 percent in non-smokers exposed at home or work. Stroke risk goes up about 20 to 30 percent.
- Children of smokers have more asthma attacks, ear infections, pneumonia, and sudden infant death (SIDS).
- Thirdhand smoke is the residue that sticks to clothes, hair, furniture, walls, and car interiors. It releases chemicals back into the air for months. Infants and toddlers - who put hands and toys in their mouths - get the highest exposure.
- Smoking outside is not enough. Smoke and residue follow you back indoors on clothes and hair. The only fully smoke-free home is one where no one smokes - and no one smokes in the car.
- Quitting helps your whole household. Children of parents who quit are less likely to start smoking themselves.
