Which of the following is a common side effect of narcotics?

The correct answer encompasses a range of common side effects associated with narcotics. Narcotics, also known as opioids, are medications frequently prescribed for pain management. Each of the listed side effects is well-documented in relation to narcotic use.

Nausea can occur as the body reacts to the medication, often as a result of its impact on the gastrointestinal system or central nervous system. Drowsiness is another prevalent side effect, as narcotics can depress the central nervous system, leading to sedation and a feeling of sleepiness. Constipation is particularly noteworthy because narcotics slow down gastrointestinal motility. This means that the digestive processes are inhibited, leading to harder stools and less frequent bowel movements, a commonly reported issue among those using these medications.

Considering these side effects collectively, the answer reflects the comprehensive nature of narcotic side effects, as all of them frequently occur in patients prescribed these drugs. Thus, identifying "All of the above" acknowledges the multifaceted impact of narcotics on the body.
