Chronic Marijuana Use and Chronic Obstructive Pulmonary Disease: A Case Report
Brenna S Ostertag1, Kathryn W Hendrickson2
1Internal Medicine Department, Providence Portland Medical Center, Portland, OR, USA.
Summary
Heavy, long-term marijuana smoking may be linked to chronic obstructive pulmonary disease (COPD). This case study highlights a patient with emphysema, suggesting marijuana use as a primary risk factor, even without tobacco history.
Area of Science:
- Pulmonology
- Toxicology
- Public Health
Background:
- Marijuana legalization is increasing globally for medical and recreational purposes.
- Marijuana smoke contains carcinogens similar to tobacco smoke.
- A definitive causal link between marijuana smoking and COPD remains elusive in scientific literature.
Observation:
- A case study of a patient with emphysema is presented.
- The patient's primary risk factor was daily marijuana smoking for over 35 years.
- The patient had no history of tobacco smoking or other apparent risk factors for COPD.
Findings:
- Existing research shows associations between chronic marijuana smoking and lung issues, including altered FEV1/FVC ratios and bronchitis.
- This case adds evidence suggesting a potential relationship between prolonged, heavy marijuana consumption and the development of COPD.
- The findings warrant further investigation into the pulmonary effects of long-term marijuana smoking.
Implications:
- Highlights the need for greater awareness of potential respiratory risks associated with heavy marijuana use.
- Suggests that marijuana smoking should be considered a potential risk factor for COPD in clinical assessments.
- Underscores the importance of continued research to clarify the long-term health consequences of marijuana smoking.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

2.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
