What method can carfentanil be characterized by?

Carfentanil is characterized as a super fentanyl due to its extreme potency, being approximately 100 times more potent than fentanyl itself and roughly 10,000 times more potent than morphine. This categorization aligns with its pharmacological properties, distinguishing it from other opioids and reinforcing the critical risks associated with its use.

While carfentanil’s high potency means it might be misused recreationally, its primary legitimate use is as a tranquilizer for large animals, such as elephants. This context highlights its intended applications and supports its classification as a super fentanyl. The other options do not accurately represent the properties or uses of carfentanil. For instance, it is not water-soluble, it is not a type of methamphetamine, and it is not primarily used as a recreational drug in the way that other substances might be, emphasizing the importance of understanding its unique classification and risks.
