Restaurant brands are going all-in on 4/20-themed promotions this week. Jack in the Box, Wingstop, TGI Fridays, and Another Wing are just a few food brands running promotions to celebrate 4/20—a holiday tied to weed culture. During April, Jack in the Box is offering a Pineapple Express Shake for $4.20 and has pledged to plant a tree for every pineapple shake ordered; Wingstop is offering a Blazed & Glazed flavor featuring hemp seeds now through April 20; TGI Fridays also has a Blazed & Glazed bundle, which includes chicken finger sliders and loaded fries, that’s available via Uber Eats; and DJ Khaled’s Another Wing is partnering with cannabis store The Flowery on a plant-based wing dish. YPulse told you how Millennials have been fueling the mainstreaming of weed, and their usage reached a new high (no pun intended) last year, and the 4/20 holiday is becoming a mainstream way for non-weed brands to engage with them.
