What does OG mean in cannabis? Nobody can say for sure. In everyday slang, OG means "original gangster," or more broadly something authentic and respected. On a strain name, it may borrow that slang, stand for "original" or nod to "ocean grown." Many OG strains trace their name to OG Kush, a 1990s favorite with a disputed backstory of its own. Here's what each theory claims and what the letters tell you on a menu.
What Does OG Mean, and Why Is It Contested?
Strain names weren't built on paperwork. Seeds and cuttings changed hands quietly for decades, and a 2019 genetic study noted that cannabis varieties have been kept out of the registration systems other crops use, so names are hard to check. That leaves room for competing stories, each crediting different people and places.
Hip-Hop's "Original Gangster"
OG as slang predates the strain. Dictionaries trace "O.G.," short for "original gangster," to Los Angeles street culture in the early 1970s. Hip-hop carried it nationwide, and Ice-T's 1991 album O.G. Original Gangster helped make it common. Over time, OG came to mean any person or thing respected as genuine and classic. One theory says strain names borrowed that sense: an OG strain is the real thing.
The OG Kush Origin Story
The most-told version starts in South Florida in the early 1990s, where a potent cut was making the rounds. By the mid-1990s, a clone had reached Los Angeles, picked up the OG Kush name and spread through California. Its genetics are debated too. A common claim pairs Chemdawg with a Hindu Kush plant, and some accounts add Lemon Thai. Think of all this as lore rather than settled history. For the bigger Kush family story, see our guide to Kush strains.
"Ocean Grown" and Other Theories
- Ocean grown. A popular story says Southern California growers used OG for "ocean grown," a nod to the coast.
- Original. Others say it simply means "original," marking the first or truest cut of a strain.
None comes with records that settle it. More slang lives in our cannabis glossary and our list of other names for cannabis.
The OG Family
Plenty of strains carry OG in their names, and many are described as OG Kush relatives or descendants: Tahoe OG, SFV OG, Larry OG and Skywalker OG, to name a few. Selection varies by store and changes often, so check your store's menu for what's available, and see our roundup of popular strains for more names.
OG Kush Profile: Aroma and Reported Effects
OG Kush is usually described as smelling of fuel, pine and lemon over an earthy base, sometimes with a peppery edge. People often report a relaxed, euphoric feeling that grows heavier as the session goes on. Your experience depends on the batch, your tolerance and how much you use.
What an OG Name Tells You When Shopping
An OG name suggests a family resemblance, often a fuel-forward aroma, but it doesn't promise lineage or strength. A 2019 genetic study looked at 30 named strains from dispensaries in three states, OG Kush among them, and most strains included at least one genetically mismatched sample. So read the label, where Michigan products list THC and CBD content, and ask your budtender how a particular batch smells and feels.
