"Cru Chemdawg OG" denotes a particular cannabis product from the brand CRU, which is presumably a Chemdawg OG (also known as OG Chem) strain, likely a sativa-dominant hybrid, that has been enhanced with concentrates such as kief or diamond-infused for increased potency. These infused pre-rolls merge the traits of the original Chemdawg and OG Kush strains, providing a balanced, cerebral high accompanied by robust diesel and earthy undertones.
