Where Thin Mint GSC Comes From
Thin Mint GSC is a selection from the Girl Scout Cookies family, which is generally traced to a cross of OG Kush and Durban Poison, specifically an F1 Durban Poison. That makes Thin Mint a close sibling or phenotype of the original rather than a separate cross, and different growers have used the name for slightly different cuts.
Girl Scout Cookies came out of the San Francisco Bay Area in the early 2010s and set off the Cookies craze, with breeders and brands giving individual phenotypes names that echo the cookies themselves. Thin Mint is the one known for the mint and chocolate flavor. Several sources describe it as hybrid with a slight indica lean, though some say it feels more sativa in practice.
Because the name is used by more than one grower, there is no single canonical lineage beyond GSC itself. A few seed companies also sell versions under the Thin Mint name that may behave differently from the clone cuts.
Thin Mint GSC Effects: What It Feels Like
Thin Mint GSC offers a quick, euphoric head change that feels cheerful and slightly dreamy. Mood lifts, creativity may spark, and conversation flows. The body effect follows soon after as a smooth, loose relaxation without immediate sedation.
Because it sits between indica and sativa, it is flexible. Many people use it in the late afternoon or evening, and some are comfortable using it earlier in the day in small amounts. The potency is notable: with THC often above 20%, a large dose can bring sleepiness or, for sensitive users, a flash of anxiety.
Thin Mint GSC Terpenes, Aroma and Flavor
True to its name, the aroma is minty and sweet, with chocolate, earth and a faint pine or citrus undertone. The smell is distinctive and cool rather than candy-sweet.
The inhale is smooth with mint, cocoa and herbal sweetness, and the exhale has a slightly earthy, peppery finish. Caryophyllene and limonene are commonly reported lead terpenes in GSC-family cuts, with myrcene behind them, though the exact numbers vary from batch to batch.
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
- Limonene: bright citrus, also found in lemon and orange peel
- Myrcene: earthy, musky and herbal, also found in mango and hops
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
Side Effects and How to Use Thin Mint GSC
Dry mouth and dry eyes are the most common effects. At higher doses some people feel dizzy, overly sleepy or anxious. Start low, keep water nearby and give it time before taking more.

Growing Thin Mint GSC
- Difficulty: Moderate
- Flowering: 8–10 weeks
- Yield: Medium
- Height: Medium
- Environment: Indoor or greenhouse; outdoor in warm, dry climates
Thin Mint GSC grows as a medium-sized, branching plant with dense, frosty flowers. Like other GSC-family cuts it is prone to mold in humid conditions, so airflow and trimming of the interior canopy matter. In western Oregon and Washington an outdoor crop is at risk during wet autumns, and indoor growing or greenhouse use is safer. Yields and flowering time vary by cut.
Home-grow rules depend on the state: adults can grow at home in states such as California (six plants per residence), Michigan (12 per residence) and Oregon (four per household), while Washington and Illinois allow home growing only for registered medical patients. Check your state in our cannabis laws by state guide before you plant anything.
