Before 4/20, the cannabis industry in the US was far from calm. Spannabis, a festival in Barcelona, Spain, saw the industry gathering for two weeks and passing around jars of live rosin like it was ambrosia at a wild stoner party. Meanwhile, back on the West Coast, strains like Duck Sauce in LA, Mitten Cake Batter in Oregon, and Apple Butter in Washington were gaining popularity. Leafly rounds up the best strains worth smoking each month after growing, shopping, smoking samples, and parsing search traffic. The top strains in March included Banana OG, Modified Grapes, Apples & Bananas, Permanent Marker, and Zortzi. In terms of new product releases, Teds Budz released Duck Sauce, which was pheno-hunted in collaboration with hip hop artist Eastside Eggroll, and Torus brought out Apple Butter. Additionally, Premier Cannabis won Best Rosin at the NW Leaf Bowl for their Grapefruit MTN strain live rosin.
