What is a potential acute effect of opiate use?

Decreased respiratory function is a well-documented acute effect of opiate use. Opiates function as central nervous system (CNS) depressants, leading to sedation and the potential for respiratory depression, which can be life-threatening. When opiates bind to specific receptors in the brain, they can significantly slow down the respiratory rate, which is particularly dangerous in situations of overdose. This characteristic makes monitoring respiratory function crucial in settings involving opiate administration or in cases of suspected abuse.

In contrast, the other options, such as increased energy, enhanced judgment, and increased alertness, are typically not associated with opiate use. Instead, opiates are more likely to induce a calming effect, resulting in sedation rather than heightened physical or cognitive function.
