What is classified as a preparation derived from opium or its derivatives?

A preparation derived from opium or its derivatives is classified as a narcotic drug. Narcotic drugs encompass substances that have a sedative effect and can create feelings of euphoria, which is often associated with opiate compounds. These drugs have significant medical applications, particularly in pain management, but they also carry a risk for abuse and addiction due to their psychoactive properties.

In contrast, cannabis refers to a different class of substances that come from the Cannabis sativa plant and are not derived from opium. Medicinal extract is a broader term that can refer to natural products extracted for therapeutic use but does not specifically denote substances derived from opium. A controlled substance is a legal regulation category that includes narcotics but is broader and encompasses many drugs, not specifically those derived from opium or its derivatives. Hence, the most precise classification for a preparation from opium is indeed a narcotic drug.
