OG Kush: Cultivar Profile With Sources, Lineage Claims and Lab Data Limits

OG Kush is a widely sold cannabis cultivar (commonly called a strain). This page keeps four things apart: what the name is, what people say about its ancestry, what laboratories have actually measured, and what research exists. This page is information only, not advice to use, buy or grow anything. Where a finding is thin we say "Proper evidence not found," and we describe evidence as "insufficient evidence" when it comes from one small study or one case.

Identity and lineage claims

The name is spelled several ways (OG Kush, O.G. Kush, Original Kush). An editorial profile says the exact origin is "pretty hard to nail down," and that it is often described as a mix of Chemdawg and a Hindu Kush landrace.[1] A seed company page quotes a different account from named people in the Florida and California cannabis scene: Triangle Kush and OG Kush seeds made in south Florida in 1991, with the writers insisting Chemdawg is not a parent.[2] The same page also lists two earlier stories that do say Chemdawg was involved, including one in which the "OG" tag meant "Ocean Grown."[2] One popular story names a Florida man, Matt "Bubba" Berger, as a breeder behind the strain, while others read "OG" as "Original Gangster."[1]

None of these accounts is a peer-reviewed record, and they contradict each other. We list them as reported lineage with low confidence. See how lineage claims and breeder attribution work. A seed-variety database lists 41 different seed-company entries under the OG Kush name,[3] so a single "OG Kush" does not exist. For more on name overlap, see cultivar names, aliases and conflicts.

Classification

Retail labels differ by source. One editorial profile calls it hybrid-dominant,[1] a seed company lists its version simply as an indica,[2] and a genetics study used a 55 percent sativa figure taken from an online strain database.[4] Peer-reviewed genetic work found that the common sativa, indica and hybrid groupings did not match the genetic groups in its 122 samples.[4] In a terpene study of cultivars from one California dispensary, OG Kush samples were THC-producing and fell in a group of cultivars marked by myrcene and limonene.[5] Read why labels do not predict effects for more.

Appearance

An editorial profile describes dense, frosty flowers with an earthy, woody aroma.[1]

Aroma and constituents

In a study of 233 samples from one California dispensary over about a year, 10 samples sold as "Og Kush" were measured for terpenes by gas chromatography.[5] This is a dataset, not a batch. Values below are reported as a value plus or minus standard deviation, in mg per gram of plant material:

The large standard deviations show samples under one name differed. The author also states that cultivar names are used with "obscure and inconsistent nomenclature."[5] Learn more about these compounds in terpenes in cannabis.

Genetic testing of four OG Kush samples bought in Colorado and California did not show one uniform genetic identity,[4] and a later study found some OG Kush samples were close genetic matches while others were only loosely related.[6] Across the four names that study tested, genetic outliers tended to smell different to panelists.[6]

Potency

Source-backed results come from a University of Northern Colorado study that bought four OG Kush flower samples at Colorado dispensaries and sent them to a third-party laboratory. The lab used liquid chromatography and calculated total THC as THC plus 0.877 times THCA.[7] These are four single samples, each tested in two to three replicates; the paper does not give test dates.

The same study found that across all 23 samples, measured THC averaged 14.98%, well below label values.[7] We do not offer a typical value for OG Kush: composition varies, and verified batch data for any particular product you may meet was not available to us. See how to read a cannabis COA and laboratory variability.

Reported experiences

An editorial profile describes a "cerebral and couchlock" mix of effects.[1] That is a consumer-style description, anecdote only, and it is not controlled research. It cannot predict what any person will feel.

Research

Proper evidence not found for OG Kush as a named product in human clinical trials. We searched Europe PMC for the name with clinical-trial terms and found chemistry, genetics and market studies only. General cannabinoid evidence is on THC and clinical research overview; those pages do not validate this cultivar.

Safety

THC can impair thinking, memory and body movement, and anxiety or panic are more common when a product is strong.[8] Because label numbers can differ from measured values,[7] a product's strength can be a surprise.
