A recent study reveals that marijuana users have higher levels of heavy metals in their blood and urine compared to non-users.
According to a report published on Wednesday by The Hill, the study was conducted at Columbia University's Mailman School of Public Health using data from over 7,200 participants of the National Health and Nutrition Examination Survey.
The research segmented participants into five categories, including non-marijuana/non-tobacco, exclusive marijuana, exclusive tobacco, and dual marijuana and tobacco use. The research analyzed participants’ blood for five distinct metals and their urine for sixteen different metals.
Postdoctoral researcher, Katlyn McGraw, stated, “Our results therefore indicate marijuana is a source of cadmium and lead exposure.”
