High Levels of Toxic Metals in Marijuana: A Health Alert

By Sechat

According to a new study, individuals who regularly use marijuana not subjected to rigorous quality standards have alarming levels of lead and cadmium in their bodies. These toxic metals, also found in tobacco products, now add to the dangers of uncontrolled cannabis consumption. 

Marijuana, classified as the third most consumed drug in the world, surpassed only by tobacco and alcohol, reveals a concerning aspect.  

"Like tobacco, cannabis is a hyperaccumulator of metals," warns researcher and postdoctoral fellow at the Mailman School of Public Health at Columbia University in New York, and one of the study's authors, Katlyn McGraw in an interview with US News.  

McGraw explains that cannabis absorbs metals from the soil, depositing them in its leaves, stems, and buds. Thus, when marijuana is smoked or inhaled, people may inadvertently be using these toxic metals. 

The risks associated with cadmium levels include a range of adverse health effects, such as heart and vascular diseases. Lead, on the other hand, is a potent neurotoxin, especially harmful to young individuals, and is also correlated with heart diseases. 

The researcher emphasizes that in the United States, where the study was conducted, the absence of national regulation compromises the quality standards of marijuana plants.  

"At this time, it is imperative that we establish federal regulations to ensure that newly introduced products to the market are strictly controlled for contaminants, encompassing not only metals but also pesticides, mold, and other harmful substances," she emphasizes. 

She urges consumers to be aware of the potential risk of exposure to toxic metals when purchasing marijuana.  

"It is essential to consider the amount and frequency of marijuana use, as this may represent continuous exposure to these harmful metals, known to be detrimental to health," warns McGraw, who stresses that it is time to look beyond cannabis as a mere recreational plant and start a conversation about the importance of regulations to protect public health in the face of this growing challenge.
