710

The number 710 rotated 180° reads "OIL," referencing cannabis concentrates (hash oil, wax, shatter, rosin, live resin). The upside-down "OIL" is an older automotive-industry joke predating cannabis use. Cannabis adoption is most credibly traced to TaskRok, an artist affiliated with BeeHive Oil Clothing, who in a 2010 TinyChat proposed 710 as an alternative to 420 specifically for extracts — a moment he later described in a 2012 Facebook post and 2015 Leaf Online interview. TaskRok released the tracks "7:10" and "Boil That Oil" (2011). The first 7/10 Cup was held in Denver on July 10, 2013; LA Weekly declared "710 is the new 420" the same year; High Times added a concentrates category to the Cannabis Cup in 2014. ⚠️ TaskRok himself declines full ownership of the term, noting the upside-down oil-cap joke predated him. 710 now ranks as the leading annual concentrate-purchase day in the U.S. legal market.
