Question explored with the scientific record
Why would a couple of drags of a cigarette stop my delirium
A couple of drags can genuinely clear withdrawal fog in a smoker, but nothing here shows nicotine treats delirium, and nicotine can cause unconsciousness at higher doses.
The most likely explanation is that what you call delirium is nicotine withdrawal, not true delirium. In heavy smokers, acute abstinence measurably worsens working memory and raises withdrawal symptoms [1], and withdrawal reliably worsens mood and anxiety [5]. A drag reverses that within minutes. That is relief of a drug deficit, not treatment of a brain injury.
The receptor evidence fits the same story. Nicotinic receptors stay elevated for up to a month of abstinence and only normalize by 6 to 12 weeks [6], so a deprived brain is primed to respond to a hit. Blocking those receptors with mecamylamine impairs learning, recall, and reaction time, and hits the elderly hardest [2]. That is the mirror image of what a drag does.
The danger is real. A young woman using multiple nicotine patches lost consciousness and took five hours to recover after removal [3]. Nicotine is not a benign stimulant at dose.
| Finding | What the record shows |
|---|---|
| Abstinence and cognition | Working memory drops during abstinence [1] |
| Receptor density | Elevated up to 1 month, normal by 6-12 weeks [6] |
| Receptor blockade | Impaired learning and recall, worse in elderly [2] |
| High-dose nicotine | Unconsciousness, full recovery in 5 hours [3] |
This retrieval contains no study of nicotine for delirium itself, so I cannot tell you it works for that. If this is a hospitalized or confused person, get them assessed; delirium has treatable causes [4].
My call: the drag is treating your own withdrawal, not delirium, and it is not a safe or studied treatment. Confidence: moderate on the withdrawal explanation, low on anything beyond it.

Modeling the nicotinic receptor loss in dementia using the nicotinic antagonist mecamylamine: Effects on human cognitive functioning
Acute mecamylamine produced dose-related impairments in new learning, recognition memory, and reaction time in healthy young and elderly never-smokers, with enhanced elderly sensitivity, suggesting that nicotinic receptor loss contributes to dementia-related cognitive deficits.

Progressive nicotine poisoning by multiple transdermal nicotine patches
A 23-year-old woman who used multiple transdermal nicotine patches in a suicide attempt developed progressive nausea, vomiting, and unconsciousness; after patch removal and skin washing, mental status fully recovered within 5 hours and urinary cotinine was elevated.
