Rising illicit drug Adulterants: Xylazine and levamisole

Area of Science:

• Forensic Toxicology
• Analytical Chemistry
• Public Health

Background:

• Illicit drug supplies are increasingly adulterated with xylazine and levamisole.
• These adulterants present unique toxicological challenges and clinical implications.

Purpose of the Study:

• To review the mechanisms of action, prevalence, and detection methods for xylazine and levamisole.
• To discuss the clinical implications of xylazine and levamisole adulteration.
• To examine analytical methodologies for identifying and quantifying these contaminants.

Main Methods:

• Comprehensive literature review of xylazine and levamisole adulteration.
• Analysis of various analytical techniques including GC-MS, HPLC-MS, and HPLC-MS/MS.
• Evaluation of the strengths and limitations of different detection methodologies.

Main Results:

• Xylazine and levamisole adulteration is a growing concern with significant public health implications.
• Accurate identification and quantification of these adulterants require sophisticated analytical techniques.
• Existing methods face challenges in sensitivity, specificity, and throughput.

Conclusions:

• This review provides a resource for clinicians and toxicologists managing xylazine and levamisole exposure.
• Understanding adulterant analysis is crucial for informing public health interventions and treatment strategies.
• Further research into rapid and reliable detection methods is warranted.
