History And Admission Findings:
A 35-year old patient suffering from a borderline personality disorder was admitted to our clinic with ingestions of cigarettes seven times within 15 months. The patient showed symptoms of a nicotine intoxication with agitation, hypertension, tachycardia, dizziness and nausea after ingestion of 7 up to 20 cigarettes.
Diagnosis:
Mild nicotine intoxication.
Treatment And Course:
After therapy with gastric lavages, activated charcoals and saline cathartics forced acid diuresis were performed in all seven cases of intoxication. All courses were without complications and unit every time the patient could be transferred to the psychiatry within 24 hours after the hospitalization in our clinic.
Conclusion:
An ingestion of more than 6 cigarettes is considered a life-threatening intoxication for adult persons. In spite of the ingestion of 7 up to 20 cigarettes our patient never showed any symptoms of a severe or life-threatening nicotine intoxication. In the last decades no lethal nicotine intoxication after ingestion of cigarettes in adults was published in the literature.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
