>They predicted that because marijuana is known to accumulate metals, individuals would have higher metal biomarker levels than those who did not use the drug, and the study confirmed that marijuana is a source of cadmium and lead exposure.<<
i dont think ive met any grower that is not highly selective, about soils and amendments used for culture.
so far i see no mention of regionality regarding user demographic, or source of cannabis.
I'd expect method of use, especially method of smoking, to have a greater impact than the cannabis itself (i.e. a metal pipe lit by a BIC lighter VS a glass pipe lit by hemp cord)
study is about the plant being “good at” grabbing the bad stuff.

but to your point it would also make a difference in how and where the plant were grown.
the article lacks a lot of details that would make the study useful. or not.

what about vaporizing concentrates with concentrated sunlight, or lasers?
