Key Findings:
- Heavy metal and phthalate contamination in CBD may counter-balance its proposed health benefits.
- Heavy metals (Pb, Cd, As, Hg), phthalates, and CBD label accuracy were quantified in CBD products.
- Only 42 % of products fell within ±10 % of the CBD claimed on the manufacturer label.
- Low-level heavy metal and phthalate contamination of edible CBD was pervasive.
- Tight regulations for CBD product label integrity are needed.
