Question

which issue is related to long - term heroin use?
○ pleasure
○ depression
○ hypoxia
○ mood swings

Explanation:

Long - term heroin use can disrupt the body's oxygen supply mechanisms. Hypoxia is a condition where there is a deficiency in the amount of oxygen reaching the tissues. Heroin can affect the respiratory system, leading to decreased oxygen intake and subsequent hypoxia. Pleasure is a short - term effect of heroin use, not a long - term issue related to its use. Depression and mood swings can be associated with heroin use, but hypoxia is a more direct physiological consequence of long - term heroin's impact on the respiratory and circulatory systems related to oxygen delivery.

Answer:

C. hypoxia
