Question

morphine, codeine and heroin are all examples of

all of the above

hallucinogens

stimulants

narcotics

Explanation:

Morphine, codeine, and heroin are opioids, which fall under narcotics (substances that relieve pain, induce sleep, and can be addictive). Hallucinogens cause hallucinations (e.g., LSD), and stimulants increase activity (e.g., caffeine). So they are narcotics, not the other options.

Answer:

D. narcotics (assuming the options are labeled as A: all of the above, B: hallucinogens, C: stimulants, D: narcotics; if labels differ, adjust to the correct identifier with "narcotics")
