The GSC, historically better known as Girl Scout Cookies, is a hybrid developed in California by crossing a OG Kush and a Durban Poison. This strain quickly gained a reputation among California’s medical communities before spreading worldwide, winning several awards along the way at the Cannabis Cup.
Its THC content, which can reach up to 28%, makes it one of the most potent hybrid strains on the market. It’s recognizable by its dense, tightly coiled buds, purple-tinged leaves, and orange pistils, all covered with a generous layer of trichomes.
Why «GSC» instead of «Girl Scout Cookies»?
Around 2018–2019, the American organization Girl Scouts of America asserted its rights to the name «Girl Scout Cookies,» which was being used without a license by many breeders and dispensaries. Faced with the threat of legal action, a large portion of the industry switched to the abbreviation GSC to continue marketing the variety without legal risk.
In reality, the two names refer to exactly the same strain, and «Girl Scout Cookies» remains widely used in everyday language, particularly in France, where the trademark dispute does not have the same scope.
GSC Phenotypes: Thin Mint and Platinum Cookies
GSC comes in several phenotypes, each with significantly different characteristics, although they all share a flowering time of 9 to 10 weeks:
Thin Mint features thinner, more slender buds, a more pronounced sativa dominance, and distinct minty notes that contrast with the strain’s classic earthy profile.
Platinum Cookies On the contrary, it produces dense, heavily frosted buds, offering a more indica-dominant profile and more sedative effects, which are popular for evening use.
GSC's Aromas and Terpenes
The GSC's aromatic profile is based on three dominant terpenes: the caryophyllene (spicy and peppery notes), the limonene (citrus fruits) and the’humulene (hops, earthy). This combination yields a sweet, earthy aroma, accented by notes of nutmeg and a hint of lemon and mint on the finish.
What effects can we expect from the GSC?
GSC produces a rapid high characterized by euphoria and mental clarity, before giving way to deep physical relaxation. This dual effect, inherited from its Indica and Sativa parents, makes it a variety that is appreciated for both recreational and medical use.
Medically, it is frequently used to relieve chronic pain, nausea, and loss of appetite. However, its high THC content means it is best suited for experienced users: too high a dose can quickly lead to an overwhelming rather than pleasant effect.
