Mephedrone (4-methylmethcathinone)-related deaths

Area of Science:

• Forensic Toxicology
• Cardiovascular Pathology
• Pharmacology

Background:

• Reports on fatalities associated with 4-methylmethcathinone (mephedrone) are infrequent.
• Understanding the toxicological profile of mephedrone is crucial due to its recreational use.

Observation:

• Four cases of death involving mephedrone were analyzed.
• Mephedrone was detected in femoral venous blood in all four cases, with concentrations ranging from 0.13 mg/L to 2.24 mg/L.
• One death was directly attributed to mephedrone's adverse effects, complicated by cardiac fibrosis and coronary artery disease.

Findings:

• Case 1: A 49-year-old female died with mephedrone (0.98 mg/L) detected.
• Case 2: A 19-year-old male died due to mephedrone (2.24 mg/L) and 3-TFMPP.
• Case 3: A 55-year-old female died from combined mephedrone (0.13 mg/L) and methadone (0.3 mg/L) effects, along with other prescribed medications.
• Case 4: A 17-year-old male driver died in a collision with mephedrone (0.24 mg/L) detected.

Implications:

• Mephedrone can be a primary cause of death or contribute to fatalities, especially when combined with other substances.
• This highlights the importance of comprehensive toxicological screening in post-mortem investigations.
• Further research is needed to fully elucidate the cardiovascular and systemic toxicity of mephedrone.
