Tobacco and Asthma: Understanding the Risks and Impact

Tobacco smoke is a major asthma trigger. It contains 4,000+ chemicals, many airway irritants. Inhaling smoke inflames and narrows airways, causing attacks.

Long-Term Effects

• Worsens asthma over time; damages airways, increases sensitivity to other triggers.
• Reduces lung function.
• Increases respiratory infection risk (immune impairment).
• Elevates heart disease/stroke risk (already higher in asthma).

Quitting Tips

• Set a quit date.
• Enlist support from friends/family.
• Use nicotine replacement or medications.
• Join a support group/forum.
• Persist—quitting is hard but worth it.

Quitting smoking is one of the best steps to improve asthma control and overall health.
