KNOWLEDGE CENTER
Know the enemy.
Facts drawn from public health authorities, the World Health Organization, the US Centers for Disease Control and Prevention, and the US Surgeon General.
The Hard Truth
Quitting smoking can add up to 20 years to your life, quitting before 40 avoids roughly 90% of the excess death risk (NEJM, US Surgeon General).
Cigarette smoke contains 7,000+ chemicals, including 70+ known carcinogens.
Vape aerosol contains nicotine, ultrafine particles, heavy metals (lead, nickel, tin) and volatile organic compounds.
Smoking damages nearly every organ in the human body, and vaping delivers the same addictive nicotine.
Smoking is the leading cause of preventable death worldwide.
EVALI, vape-associated lung injury, has hospitalized thousands and killed dozens (US CDC).
Nicotine harms adolescent brain development, up to age 25.
Smoking and vaping both raise heart rate, blood pressure, and can worsen anxiety.
Secondhand smoke and secondhand vape aerosol both expose non-users, including children.
Recovery Timeline
20 minutes
Heart rate begins returning to normal.
8 hours
Blood oxygen levels start improving.
12 hours
Carbon monoxide in the blood drops to normal.
24 hours
Heart attack risk begins to decrease.
48 hours
Taste and smell start to sharpen.
72 hours
Breathing gets noticeably easier. Nicotine is out of your system.
2 weeks
Circulation improves; walking is easier.
1 month
Coughing and shortness of breath decrease.
3 months
Lung function improves significantly.
6 months
Respiratory infections drop.
1 year
Heart disease risk cut roughly in half.
5 years
Stroke risk drops toward that of a non-user.
10 years
Lung cancer risk roughly halved vs. continuing users.
15 years
Heart disease risk approaches a non-user's.
Topics
The first 72 hours
Withdrawal peaks around 72 hours. Irritability, cravings, brain fog. This is the addiction dying, not you.
How the lungs heal
Cilia, the tiny hairs that clear mucus, regrow within weeks. Lung function measurably improves within 3 months.
The heart recovery timeline
Blood pressure and heart rate normalize within 20 minutes. Carbon monoxide clears in a day. Heart attack risk halves within a year.
Smoking, vaping and mental health
Contrary to the myth, nicotine users report worse anxiety and depression on average. Quitting improves mood within weeks.
Vaping is not a safe exit
E-cigarettes contain nicotine, ultrafine particles, heavy metals, and flavoring chemicals like diacetyl linked to lung disease. EVALI proved vape aerosol can put people in the ICU.
Cigarettes vs. vapes: what's different
Cigarettes deliver tar, carbon monoxide, and 70+ carcinogens through combustion. Vapes skip combustion but still deliver highly addictive nicotine and inhaled toxicants. Neither is safe. Neither is 'quitting'.
Money and time
A pack-a-day habit at $10/pack costs $3,650/year. A daily disposable vape at $10 costs about the same. That's a vacation. A car payment.
Smoking, vaping and skin
Nicotine constricts blood vessels, accelerating wrinkling, dulling complexion, and slowing wound healing. Quitting reverses much of it within a year.
