What's the difference between 'nod off' and 'nod out'?

'Nod off' is milder and more common, meaning to fall into a light, unintentional sleep, usually from tiredness or boredom. 'Nod out' implies a deeper, more sudden, or less controlled loss of consciousness, often with connotations of being overcome by exhaustion or drugs. 'Nod out' is more informal/slang.

Is 'nod out' only about drugs?

No, while strongly associated with drug-induced drowsiness (especially opioids), it is perfectly valid for extreme tiredness. However, context is key. Saying 'I nodded out during the film' suggests tiredness or boredom. Saying 'He's nodding out' in a certain context might imply substance use.

Can 'nod out' be used transitively?

No, it is an intransitive phrasal verb. You cannot 'nod someone out'. The pattern is always a subject who falls asleep: Subject + nod out.

Is this phrase formal or informal?

It is informal, bordering on slang. It is not suitable for formal writing, official reports, or academic essays (unless quoting informal speech or discussing the term itself). Use 'fall asleep', 'doze off', or 'become drowsy' in formal contexts.
