PhD-led indoor cannabis out of Pullman, Washington — flower, pre-rolls, infused Matchsticks, live rosin, and dab pens. Same plant scientists behind Dewey Scientific, just with their own jar on the shelf.
Our Story
Dewey started as the cultivation arm of Dewey Scientific, a Washington State University spinout founded by three Ph.D. plant biologists — Dr. Jordan Zager, Dr. Paul Mihalyov, and Dr. Mark Lange. Dewey Scientific does the genomics and breeding work; Dewey Cannabis Co. takes those phenotypes and grows them out for the shelf.
The grow room sits in Pullman, the same college town as WSU. The legal entity is still Dewey Botanicals LLC — that's the name on the license — but the consumer-facing brand was renamed Dewey Cannabis Co. in 2024 with the smile logo and yellow accent identity that fronts every jar today.
We carry Dewey at Seattle Cannabis Co. because the science actually shows up in the jar: consistent phenotype expression, terpenes that match the genetics on paper, and a cure that lights even. The Hella Dewbie is the easy weekend pickup; Matchsticks if you want infused and solventless in the same joint.
