Research progress in air monitoring for illicit drugs and its application
The monitoring of drug components as gas or particulate matter(PM)and their coexisting marker molecules in the air can provide scientific and technical support for the assessment of regional drug crimes and source tracing.To date,researches on outdoor and indoor environments in large cities in Western Europe,Northern Europe,North America,South America,Africa,and Oceania have been reported.Overseas gaseous and PM-containing illicit drugs including amphetamines,coca,cannabis,and opioids have been detected,while substantive research reports in mainland China are expected.This article analyzes future research hotspots by reviewing the current application,research progress,and existing problems of air monitoring for illicit drugs.
