Which substance is known for causing severe respiratory depression when overdosed?

• A. Alcohol
• B. Cocaine
• C. Opioids
• D. Marijuana

Answer: (C)

Opioids are particularly known for causing severe respiratory depression when an overdose occurs. This is due to their action on the central nervous system, specifically the brainstem, where respiration is regulated. When opioids bind to their receptors, they can significantly diminish the body's urge to breathe, which can lead to hypoventilation and eventual respiratory failure. This dangerous effect makes opioid overdoses a critical concern in substance abuse cases. In contrast, while alcohol can also depress the respiratory system, its effects are typically less severe compared to opioids at therapeutic or moderate use levels, and the risk of respiratory depression tends to be less pronounced in isolation than with opioids. Cocaine generally acts as a stimulant, often leading to increased heart rate and potential respiratory complications, but it is not primarily known for causing respiratory depression. Marijuana primarily affects respiratory function in different ways, often causing bronchial irritation rather than significant respiratory depression, particularly in acute situations. Understanding the distinct effects of each substance is crucial for managing and treating overdose situations effectively.
