Definition - What does Narcotic mean?
Safeopedia explains Narcotic
In the workplace, the use of narcotics can be extremely dangerous. In professions where machinery and vehicles are operated, sleepiness, a major side effect of narcotic use, can lead to accidents. Though many believe that narcotic use is illegal, from a medical standpoint, narcotics include prescription drugs like codeine, which is a legal substance. Extreme caution must be taken when using these kinds of medication, and many employers prefer staff to be on sick-leave or light duties while using these medicines.
