What is 710?

710 is a cannabis code for concentrates and dabbing—the number resembles the word "OIL" when flipped upside down.

Read upside down, "710" looks like "OIL," which made it the natural counterpart to 420 for fans of cannabis extracts. July 10 (7/10) is celebrated as an unofficial holiday focused on concentrates and dabbing. The term rose alongside the growing popularity of oils, waxes, and other extracts.
