A 2023 research carried out by researchers at New York’s Columbia College, using knowledge from the Nationwide Well being and Diet Examination Survey by the US Facilities for Illness Management, sheds mild on the potential well being dangers linked to heavy metallic buildup in hashish customers.
Notably, the research highlighted that authorized tobacco merchandise have larger contamination ranges than illicit hashish.

Hashish Customers’ Steel Ranges Examined
Hashish vegetation, often known as hyperaccumulators, take in metals from soil, water, and fertilizers at exceptionally excessive ranges.
The Columbia researchers analyzed knowledge from 7,254 contributors between 2005 and 2018, aiming to find out if hashish customers had elevated ranges of 17 totally different metals of their blood and urine.
Key Findings
- The research revealed that cannabis-only customers had 27% larger blood lead ranges and 21% extra lead of their urine in comparison with non-users of each hashish and tobacco.
- Moreover, hashish customers had elevated ranges of cadmium, with 22% larger ranges of their blood than non-users.
- Each lead and cadmium could cause long-term well being injury, together with heart problems, continual obstructive pulmonary illness, cognitive impairment and most cancers threat.
- Publicity to cadmium, a heavy metallic, can pose well being dangers, with cadmium categorised as a possible human carcinogen by the US Environmental Safety Company.
- Vaping poses extra dangers because the extraction course of for cannabidiol can introduce heavy metals and different contaminants if finished incorrectly.
- The kind of marijuana consumption methodology can affect heavy metallic absorption, with inhalation presenting larger dangers as a consequence of almost 100% lead absorption and as much as 50% cadmium absorption.
- The researchers underscored the significance of testing hashish merchandise for metallic contamination, notably in states the place it’s authorized.
Tobacco Customers Have Greater Ranges Of Heavy Metals
Whereas the research didn’t discover clear causal associations between hashish use and different evaluated components, tobacco customers displayed considerably worse outcomes, with thrice larger urinary cadmium ranges and 26% larger blood lead ranges. Authorized hashish merchandise usually bear extra stringent testing than tobacco.
“Not one of the different 15 components evaluated within the research—together with arsenic, cobalt, manganese, and mercury—confirmed a transparent causal affiliation with hashish use. And tobacco customers proved far worse off. Their urinary cadmium ranges have been thrice larger than these of unique hashish customers, for instance, whereas their blood lead ranges have been 26% larger,” reported Nate Seltenrich for Leafly.
Printed within the open-access journal Environmental Well being Views in late August 2023, the research is taken into account a big contribution to understanding the well being implications of heavy metallic publicity in hashish customers.
