What does it indicate if a user is described as "on the nod"?

When a user is described as "on the nod," it indicates that they are in a semi-conscious state. This term is often associated with the effects of certain opioids or sedatives, where individuals may demonstrate a state of drowsiness or lethargy, often characterized by a head nodding motion that occurs as they drift between consciousness and sleep. This state reflects the depressant effects of these substances on the nervous system, leading to reduced awareness and alertness.

Being "on the nod" is contrary to being alert and active, which would demonstrate a higher level of consciousness and engagement. Similarly, while euphoria can be a consequence of substance use, it does not accurately describe the semi-conscious or drowsy state that the phrase implies. Lastly, being sober and relaxed does not equate to the altered state induced by narcotics, as this would suggest full consciousness and control rather than the semi-consciousness associated with "on the nod."
