Chemdog 91 is cannabis royalty — one of the original phenotypes from the legendary Chemdog line that spawned Sour Diesel, OG Kush, and countless modern hybrids. This classic hybrid is the connoisseur's benchmark for old-school funk. Indoor-grown Chemdog 91 typically tests in the high teens to mid-20s for THC, delivering the raw, unrefined potency that made the Chem family famous.

Effects are famously talkative and euphoric at first — users report feeling happy, creative, and uplifted — before a warm, relaxing body high settles in. It is a proven daytime-to-evening strain for melting away stress, soothing aches, and quieting anxiety, with a long-lasting high that creeps before it fully lands.

The aroma is unmistakable: pungent chemical funk and kerosene-like diesel layered over sour skunk, with a piney-lemon bite on the exhale. Break open a bud and the room fills with that sharp, nose-stinging Chem signature. Flowers are dense and resinous, typically medium-green with fiery orange hairs and a heavy coat of sticky trichomes.
