On July 10 — aka 7/10, 7:10, or 710 — “Happy 710” trended on Twitter when users began discussing the new, informal annual marijuana-related holiday en masse.
The holiday was created to recognize the popularity of “dabs,” the slang term for high-THC concentrates and oils, according to High Times.
So where does the name 710 come from? It’s not like 4/20, which has a few different rumored explanations, including one involving a police radio code.
Instead, it’s something much more simple: “710” upside down spells “OIL.” Thus, a number of marijuana aficionados are saying that July 10 should be honored as “Dab Day,” the day each year when THC-laden oils and concentrates should get their due while getting their users stoned.
Pot oil extraction is the process by which concentrated cannabis oil is removed from marijuana. This is usually done by forcing butane through the cannabis in a pressurized tube, a police official told OC Weekly in 2013.
“The product extracted results in a higher concentrate ‘oil,’ which is processed via a heat source or evaporation into a semi-solid final product,” he said.
But cannabis oil extraction can be dangerous, causing occasional explosions, as the process involves butane, which can be volatile.
