What type of drug can be produced by chemical synthesis or extraction?

The correct answer indicates that a narcotic drug can be produced through chemical synthesis or extraction. Narcotic drugs often refer to substances that can relieve pain and can have sedative effects, which are primarily derived from opiates. These drugs can either be extracted from natural sources, such as the opium poppy, or produced synthetically in a laboratory setting.

In the context of narcotics, many clinically used medications, such as morphine and codeine, are extracted from natural sources, while others, like fentanyl, are entirely synthesized through chemical processes. This versatility in production methods—both natural and synthetic—positions narcotic drugs uniquely within the scope of drug formulation.

While antibiotics, over-the-counter drugs, and prescription medications can also involve both synthetic and natural methods for their production, the specific term "narcotic" is distinctly associated with both extraction from natural sources and the capacity for chemical synthesis, making it the most fitting answer in this scenario.
