Answer 1

Narcotics relax the central nervous system and can be addictive if taken for a long period of time.

What are narcotics?

• In the beginning, the term "narcotic" was used in medicine to describe any psychoactive substance that had numbing or paralyzing effects.
• Since then, it has come to be associated in the United States with opiates, opioids, most notably morphine and heroin, as well as many of the chemicals found in unprocessed opium latex.
• Morphine, codeine, and thebaine are the top three (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone or hydrocodone).

The term "narcotic" may have ambiguous legal definitions and frequently connotes harmful substances. A narcotic drug, such as heroin, is completely illegal when used in a legal setting in the United States, as is using one illegally.
