Marijuana abuse is linked to severe bullous emphysema and pneumothorax. This case highlights the potential respiratory risks associated with cannabis use, emphasizing the need for awareness.
Area of Science:
- Pulmonology
- Toxicology
Background:
- Marijuana abuse shows a global increasing trend.
- Respiratory complications of marijuana abuse are a growing concern.
Purpose of the Study:
- To report a case of severe bullous emphysema and pneumothorax in a marijuana abuser.
- To review the differential diagnosis of bullous emphysema in adults.
Main Methods:
- Case report presentation.
- Literature review of bullous emphysema differential diagnoses.
Main Results:
- A patient with a history of marijuana abuse developed severe bullous emphysema.
- The condition led to a pneumothorax, a serious respiratory event.
Conclusions:
- Marijuana abuse may contribute to the development of severe bullous emphysema.
- Differential diagnosis for bullous emphysema should consider substance abuse.
