1. pertaining to or producing narcosis.

2. a drug that produces insensibility or stupor.

In veterinary medicine the term narcotic includes any drug that has this effect, but care is needed to avoid confusion with the more common usage of the word to mean the habit-forming drugs—for example, opiates such as morphine and heroin, and synthetic drugs such as meperidine. These can be legally obtained for use in animals only with a veterinarian's prescription. The sale or possession of narcotics for other than strictly therapeutic purposes is prohibited by law.
