The recent study conducted by researchers from Lake Superior State University in Michigan has revealed alarming findings regarding the potential health risks associated with using cannabis rolling papers. The study, published in the journal ACS Omega, analyzed the elemental composition of 53 commercially available rolling papers and discovered elevated levels of heavy metals such as copper, chromium, and vanadium.
These unsafe quantities of heavy metals in rolling papers could pose serious health risks to users, especially when considering the potential for repeated exposure through inhalation. The study highlighted that some rolling papers contain copper-based coloring, which may expose users to harmful levels of copper, leading to potential long-term health problems and increased risks of developing diseases.
Researchers explained that the heavy metals in rolling papers can originate from various sources, including residual chemicals from manufacturing, ink and dyes used during production, and potentially contaminated plants used in papermaking. The study also emphasized the disparities in regulations across different states regarding acceptable levels of arsenic, cadmium, mercury, and lead in rolling papers.
The lack of unified guidance in regulating rolling papers, coupled with the varying cannabis laws across states, raises concerns about the potential exposure to toxic elements like copper among users. The researchers suggested that states collaborate to establish limits on toxic elements in cannabis and rolling papers based on their findings, urging manufacturers to eliminate the use of copper-based inks to reduce copper levels in papers and mitigate health risks.
