Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main hypothesis is that persons that smoke or smoked tobacco and marihuana have worsen lung function as compared with persons that only smoke or smoked tobacco.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

We will follow persons with already diagnosed COPD (chronic bronchitis and/or emphysema). Obtain their smoking history: tobacco and marihuana and review their pulmonary function study results. Then we are planning to compare both groups.
