Overview
- Researchers from Lake Superior State University found varying levels of heavy metals in 53 different cannabis rolling papers, posing potential health risks.
- Copper, chromium, and vanadium were among the metals detected, with some samples exceeding safe inhalation limits.
- Colored and metallic rolling papers were particularly noted for higher levels of copper, often used for aesthetic appeal.
- The study suggests that current regulations are insufficient, recommending state and federal action to establish stricter safety standards.
- Experts urge manufacturers to eliminate the use of copper-based inks and adopt safer production techniques to reduce health risks.
