Question

Quizplus · Accepted Answer

Intravenous injection or inhalation are preferred methods for opioid users seeking rapid onset of effects because these routes allow the drug to reach the brain more quickly than other methods, such as ingestion or insufflation. Intravenous injection delivers the substance directly into the bloodstream, and inhalation allows for rapid absorption through the lungs.
