This comprehensive epidemiological analysis provides critical context for cannabis clinicians treating patients with chronic respiratory diseases. Understanding the global burden and evolving patterns of COPD, asthma, and interstitial lung diseases informs risk-benefit assessments when considering cannabis therapeutics in these vulnerable populations.
This Global Burden of Disease study analyzed chronic respiratory disease patterns from 1990-2023, finding 569.2 million cases and 4.2 million deaths in 2023. While age-standardized mortality declined 25.7% overall, concerning increases occurred in interstitial lung disease and pulmonary sarcoidosis, particularly among older adults. The study tracked five major conditions: COPD, asthma, pneumoconiosis, ILD, and pulmonary sarcoidosis across all global regions. Notably, younger males showed mortality improvements especially for asthma, while older populations faced rising risks from fibrotic lung conditions.
“This data reinforces my clinical caution around inhaled cannabis delivery methods in patients with existing respiratory compromise. The rising burden of interstitial lung diseases particularly concerns me given our limited understanding of long-term pulmonary effects from cannabis inhalation.”

FAQ
Is cannabis safe for patients with COPD or other chronic respiratory diseases?
Cannabis smoking poses significant risks for patients with chronic respiratory diseases, as inhaled smoke contains irritants that can worsen airway inflammation and respiratory symptoms. While this study shows COPD mortality rates have declined overall, smoking any substance including cannabis could potentially reverse these gains in susceptible patients.
Can cannabis help treat asthma symptoms?
There is insufficient evidence to recommend cannabis for asthma treatment, and smoking cannabis may actually trigger asthma attacks due to airway irritation. Given that asthma mortality has decreased significantly according to this study, patients should stick to proven bronchodilator and anti-inflammatory therapies rather than risk respiratory irritation from cannabis smoke.
Are there safer ways to use cannabis for patients with respiratory conditions?
Non-smoking delivery methods such as vaporization, sublingual oils, or edibles may reduce direct respiratory irritation compared to smoking. However, even these methods require careful consideration and medical supervision in patients with chronic respiratory diseases, as the underlying respiratory compromise may affect drug metabolism and response.
How might COVID-19 complications affect cannabis use in respiratory patients?
The study indicates COVID-19 has impacted chronic respiratory disease burden, potentially making these patients more vulnerable to additional respiratory insults. Cannabis smoking could theoretically worsen outcomes in patients with COVID-19-related respiratory complications or those with compromised lung function from chronic conditions.
Should dosing considerations change for cannabis patients with interstitial lung disease?
Patients with ILD or pulmonary sarcoidosis, which this study shows are increasing in prevalence, may have altered drug clearance due to compromised lung function and potential liver involvement. These patients require particularly cautious approach to cannabis dosing and should avoid any inhaled forms due to the progressive nature of their underlying lung disease.
