Chemdawg

Chemdawg (also spelled 'Chemdog') is a legendary cannabis strain first cultivated in the early 1990s by breeder Greg 'Chemdog' Krzanowski from seeds obtained at a Grateful Dead concert in Colorado. Its true genetics remain shrouded in mystery and urban legend, with speculation pointing to Thai and Nepalese landraces. Chemdawg is widely regarded as one of the most influential strains in cannabis history, serving as the genetic backbone for powerhouse offspring such as Sour Diesel and OG Kush. It delivers a well-balanced but potent experience — a cerebral, euphoric head high paired with a heavy, relaxing body effect. With THC levels commonly ranging from 18–25%, it is considered an advanced strain not recommended for novice consumers.
