What is MK Ultra?
Leafly describes MK Ultra, also known as MKU and MK Ultra OG, as a potent cross of OG Kush and G13 bred by T.H. Seeds, and says it won first place in the indica category at the 2003 High Times Cannabis Cup and second place in 2004. Weedmaps adds that the Amsterdam seed bank crossed an OG Kush female from JoshD Farms in Los Angeles with a G13 male from Barney's Farm, and that founder Adam Dunn called it the first European cross to use an American OG Kush. The name comes from the CIA's MKUltra experiments of the 1950s.
Labels differ: Leafly files it as an indica, AllBud rates it 70% indica and 30% sativa, and Weedmaps lists it as a hybrid with mainly indica lineage. In practice it is an indica-dominant hybrid (here is what those labels really mean).
Look, smell and taste
Leafly describes sticky, dense, pungent flowers, and its reviewers most often pick earthy, pungent and woody as flavours. AllBud describes green buds with brown and orange hues, a strong and strange odour, and a pungent mix of skunk and earth on the palate. Weedmaps quotes the seed bank's description of frosty colas, heavy resin and a long-lasting piney aroma.
Leafly's lab-sourced data lists myrcene as the most abundant terpene, followed by caryophyllene and limonene (here is how terpenes shape aroma and flavour).
Effects people report
Leafly describes fast-acting, euphoric effects, rates MK Ultra as mostly calming, and lists sleepy, relaxed and tingly as the effects its reviewers report most. T.H. Seeds, as quoted by Weedmaps, calls the high strong and hypnotic, and AllBud describes a hard-hitting strain that takes effect quickly and leaves people relaxed and drowsy.
Dry mouth, dry eyes and dizziness are the most common complaints on Leafly, and AllBud adds headaches. This is a strong strain, so start with a small amount, and do not drive: Canada's lower-risk cannabis use guidelines advise waiting at least 6 hours after use.
THC and potency
Leafly lists MK Ultra at about 20% THC and rates it higher than average, and AllBud gives 18% THC with about 1% CBD. THC varies by grower and batch, so check the lab-tested number on the label rather than relying on either figure.
Similar strains
Its parents, OG Kush and G13, are named by all three sources, and Weedmaps lists both as the strains most similar to MK Ultra. Leafly lists Cannatonic and Ultra Sour among its offspring.
