Complex suicide with homemade nicotine patches.

Area of Science:

• Forensic Toxicology
• Clinical Toxicology
• Medicolegal Death Investigation

Background:

• Self-poisoning is a significant global health concern.
• Complex suicide cases require thorough investigation to determine the exact cause of death.

Observation:

• A 51-year-old individual died from self-inflicted poisoning.
• The victim used homemade nicotine patches derived from tobacco and ingested a lethal dose of diphenhydramine.
• The scene initially suggested an autoerotic accident due to restraints, but toxicological findings were key.

Findings:

• Toxicological analysis confirmed lethal concentrations of nicotine and diphenhydramine.
• Subtherapeutic levels of tetrazepam were also detected.
• The cause of death was definitively classified as suicidal intoxication.

Implications:

• Highlights novel methods of self-poisoning, specifically the use of homemade nicotine delivery systems.
• Underscores the importance of comprehensive toxicological analysis in medicolegal investigations.
• Emphasizes the need to consider complex scenarios where initial scene interpretation may be misleading.
