Dr. Grinspoon, named in honor of the late Harvard psychiatrist and cannabis-policy pioneer, is the Barney's Farm sativa that preserves an unusually long flowering window and the rare beaded-bud morphology of pure heirloom sativas. A reliable curiosity for adults 21+ exploring landrace-leaning sativas on the heritage end of the menu.

Aroma is honey-like with an earthy tropical backbone and a spicy exhale, a profile that tends to read distinctively on lab panels. Pinene and terpinolene lead the panel. Rarely shows up unmixed on modern dispensary shelves, but heritage cultivators in California and Europe maintain selected lines, and the cultivar surfaces occasionally in cup-circuit drops through 2026 as a tribute to Lester Grinspoon's legacy.
