Metal and bacterial contamination of illicit drugs

We read with great interest the article by Aghababaei et al. . It is a valuable study that furthers the significant base of literature on contamination of illicit drugs. We wish to comment on several aspects of the study, and to evaluate the methodology and findings in the context of prior work.
The reasons for intentional drug contamination are diverse, including bulking or enhancement of drug effect. Unintentional contamination may follow manufacturing impurities or storage effects. Occasionally, the reasons for contamination are unclear, such as the recent outbreak of brodifacoum tainted synthetic cannabinoids in the United States .
Metal contamination of illicit drugs has been understudied, in part because many analyses have used techniques intended to detect volatile compounds, or utilized liquid chromatographic techniques without specifically evaluating for metals. Prior reports have investigated metals in methamphetamine, cannabis, heroin, opium, and...
