Permanent Marker is (Biscotti x Sherb Bx) x Jealousy, bred by Seed Junky Genetics and selected by Doja Pak. Leafly named it 2023 Strain of the Year. Unlike most dessert-family hype strains, its published profile is myrcene-led, with limonene and caryophyllene next. As of October 3, 2026, it can be sold as hemp only until December 11, 2026.
In this note
Permanent Marker is a Seed Junky Genetics cross of (Biscotti x Sherb Bx) x Jealousy, selected by Doja Pak. Leafly named it 2023 Strain of the Year. Its published terpene profile leads with myrcene, then limonene and caryophyllene. Among the big-name hype strains it has an unusual nose: reviewers describe it as solvent, floral, soapy and sweet gas, the smell of a freshly opened marker.

What is Permanent Marker a cross of?
Three Cookies-adjacent lines are stacked here. Biscotti brings the Cookies dough and spice. Sherb Bx is a backcross of Sunset Sherbet that adds sweetness. Jealousy, also from Seed Junky Genetics, is the parent usually credited with the gas. The result is a strain whose aroma is not cream or fruit. That difference is what got it attention in a market full of dessert names.
Where it sits among the files
Next to four caryophyllene-led hype strains, Permanent Marker differs on paper as well as in the jar:
| File | Lead terpene (published) | Second | Third | Nose in one line |
|---|---|---|---|---|
| Permanent Marker | Myrcene | Limonene | Caryophyllene | Solvent, floral, soapy gas |
| Gary Payton | Caryophyllene | Limonene | Linalool | Diesel, pepper, dried fruit |
| GMO | Caryophyllene | Limonene | Myrcene | Garlic, chemical, savory |
| Runtz | Caryophyllene | Limonene | Myrcene | Sweet tropical fruit |
| Apple Fritter | Caryophyllene | Limonene | Pinene | Baked apple, pine |
All the profiles share the same few terpenes. The order and the proportions differ, and the compounds outside the panel make up the rest. For that reason, a terpene table alone cannot tell a Permanent Marker Batch from a mislabeled one.
COA checklist for a Permanent Marker bag
- The Batch code on the COA matches the bag.
- Delta-9 THC is at or below 0.3% dry weight. That is the federal hemp test until December 11, 2026.
- Total THC is reported or computable: delta-9 + (THCA x 0.877). Example: 24.8% THCA with 0.19% delta-9 gives 21.94%.
- Myrcene’s share of total terpenes. A profile led by myrcene fits the published file. If caryophyllene leads by a wide margin, ask the seller about the cut.
- The lab is ISO/IEC 17025 accredited, with a sample ID you can verify.
Log 2026-10-03: total THC was already in the rules, in one place
As of October 3, 2026, high-THCA flower sits in a gap between two federal rules.
| Rule | What it measures | Where it applies |
|---|---|---|
| USDA hemp production rule, 7 CFR 990.25 | Total THC, counting converted THCA, on a dry-weight basis | Pre-harvest compliance sampling of the crop |
| Statutory hemp definition, 7 U.S.C. 1639o (current text) | Delta-9 THC, 0.3% dry weight | What “hemp” means in federal law, including at retail |
| Section 781 of P.L. 119-37, effective for THCA on December 11, 2026 under H.R. 6500 | Total THC “including tetrahydrocannabinolic acid”, 0.3%, plus 0.4 mg per container for final products | The definition itself, so it applies everywhere |
When Section 781 takes effect, the gap closes. A Permanent Marker Batch at 24.8% THCA counts as about 21.9% total THC, roughly 73 times the limit. The licensed-dispensary lane does not change: in adult-use states, licensed retailers keep selling Permanent Marker as marijuana under state law. Until December 11, state law still decides where the hemp lane is open. Several states closed it to flower before the federal date.
