E172: 420 2026 — Live! Inside the Data on Cannabis's Biggest Weekend

Live from 4/20/2026 — Cy Scott (Headset) and Emily Paxhia (Poseidon) break down the fully-closed 420 weekend (Fri 4/17 – Sun 4/19) across every connected US and Canadian market in the Headset sample. Plus the culture, the myths, and what Grok 4.20 has to do with any of this. The headline numbers 13.4M units sold in US connected markets over the 420 weekend — +17% vs an average weekend. US dollars only +5% vs baseline. The 12-point gap between unit lift and dollar lift is the textbook 420 promo signature. US discount depth hit 32.8%, up +8.3 pp. Canada ran a completely different 420 — discount rates barely moved (+0.4 pp), units only +4.3%. The holiday is more flag-wave than promo event up north. Category & brand breakouts Flower anchors US dollars ($77M, units +11%). Vapor Pens $49M (+16%). Pre-Roll US unit leader at 4.1M (+14%). Edibles the discount play — +9.9 pp deeper promos, units +30%. Canada: Pre-Roll beats Flower in dollars ($13M vs $10.9M) — a structural difference from US markets. Michigan dominates the top-mover list: NOBO +$510K in dollars (units only +26%, price/mix doing the work). MKX Oil 167K vapor pen units, +106%. Peninsula Cannabis +220%, Michigrown +131%, Hytek +113%, Alien Labs +97%. Small-base explosions: Flavors Cannabis Co. +712%, Indica Cannabis Co. +459%. Michigan dispensary "House Brand" 1g flower ran 60–64% off — nearly $500K in discount dollars from that state alone.
