Market Insights Snapshot
In May 2026, 1Spliff concentrated 96.24% of sales in Pre-Roll, with that category up 7.82% month over month and 2.21% year over year, while the overall brand rose 6.20% year over year and average price fell 2.02%. Flower expanded its share to 2.76% on a 35.96% month-over-month lift, and Vapor Pens held 0.99% share with a 7.21% month-over-month increase, signaling that non–Pre-Roll lines, though small, are scaling faster than the Pre-Roll core. This pattern implies the brand is still anchored in Pre-Roll but is beginning to diversify at the margins, using price easing and selective category expansion to add volume without disrupting the core mix.
With Pre-Roll at 96.24% share alongside a May 2026 rank of 15 in Pre-Roll in Ontario, the 7.82% month-over-month gain in the core outpaced the 2.21% year-over-year change, while Flower’s 35.96% month-over-month surge and Vapor Pens’ 7.21% month-over-month rise indicate a testing phase rather than a pivot. The combination of a 2.02% decline in average price and a 6.20% year-over-year sales increase suggests a volume-led stance that sustains the Pre-Roll ranking while probing adjacent categories to hedge reliance on a single format. The implication is a positioning strategy that prioritizes defending Pre-Roll share and rank while planting small footholds in Flower and Vapor Pens to capture incremental demand without diluting the brand’s identity.
Competitive Landscape
1Spliff is ranked #15 in ON Pre-Roll in May 2026, a 2-position improvement from #17 year over year, but flat versus February 2026 at #15 while still trailing its peak of #14 in March 2026; meanwhile, Back Forty / Back 40 Cannabis climbed from #3 to #1 as sales grew 66.8%, and General Admission slipped from #1 to #2 with a 13.6% YoY decline. Further, Jeeter eased from #2 to #3 alongside a 48.4% sales drop, while Thumbs Up Brand advanced from #7 to #4 with 40.6% YoY growth; against this mix of upward and downward mobility among leaders, 1Spliff’s modest YoY rank gain and three-month stasis imply a stable mid-pack position that will require share capture to break back above #14.

Notable Products
Grape Escape Pre-Roll 7-Pack (3.5g) posted the standout movement in May 2026 with a 24.2% month-over-month rise to rank 3, while Cannon Pre-Roll (1g) gained 8.1% and held rank 1. Hawaiian Snowcone Pre-Roll 10-Pack (3.5g) slipped 3.5% at rank 2 as its sibling Hawaiian Snowcone Pre-Roll 7-Pack (3.5g) advanced 20.7% at rank 4, indicating pack-size substitution within the same flavor family. With all ten of the top-ten SKUs in Pre-Roll and six of the top eight posting gains between 8.0% and 24.2%, the mix points to a strategy concentrating volume in multi-pack Pre-Rolls rather than single sticks.
