Cannabis plants have an inherent ability to absorb heavy metals from the soil, making them useful for remediating contaminated sites. But this ability to soak up toxic metals may also make cannabis dangerous for consumers who ingest it.
A new analysis, led by researchers at Penn State, examines the ability of cannabis plants to absorb heavy metals and discusses the resulting health impacts on consumers. The team proposes a blueprint of strategies for growers to alleviate heavy-metal uptake by their crops, reported medicalxpress.com
“Heavy metals, such as lead, are known to be carcinogenic,” said Louis Bengyella, assistant research professor of plant science at Penn State, who noted that “Consumers could unknowingly be exposed to these toxic metals,” which he called “particularly problematic …
