The Chem D cannabis strain is an expansion of the famous Chemdawg strain lineage. Nepalese and Thai landrace strains are believed to be the parents of Chemdawg, which has been used to create All-star strains like Sour Diesel and OG Kush. In the Chem D strain, Sour Diesel and OG Kush were crossed to create this potent hybrid. It seems the best of both worlds from beloved parent strains were passed onto Chem D. The earthy musk aroma is like a mix of gasoline and insect repellent with some citrus undertones. Smoking or vaping Chem D is earthy, but sweet, and leaves a peppery aftertaste.
