Permanent Marker Strain Guide: Effects, THC, When to Use It

Permanent Marker is an indica-dominant hybrid bred by JBeezy of Seed Junky Genetics and selected by Doja Pak, crossing Biscotti and Sherb Bx with Jealousy. Reported THC runs 25–35%, among the highest of any widely sold strain. It was Leafly’s Strain of the Year for 2023, and the profile is soap, gas, and marker ink.

What Is Permanent Marker?

Permanent Marker is the most decorated cannabis strain of the mid-2020s. Bred by JBeezy of
Seed Junky Genetics and selected by Doja Pak, it crosses
Biscotti and Sherb Bx with Jealousy. High Times
named it Strain of the Year in late 2022 and Leafly followed with the same title for 2023.

The name is a description, not a metaphor. The dominant aroma is a sharp chemical-floral note that
genuinely reads as permanent marker or scented soap, sitting over gas and a sweet pastry base. It is
polarizing in the same way that heavily perfumed things usually are.

It is also one of the few strains where the hype and the lab results point in the same direction.
Reported THC of 25–35% puts it at the top of the commercial range, and unlike many high-testing
cultivars it has a terpene profile substantial enough to justify the attention.

At a Glance

Lineage: A Stack of Modern Winners

Biscotti — a Gelato #25 and Sour Florida OG cross — supplies the pastry sweetness
and a good deal of the density. It is one of the strains that defined the late-2010s dessert wave.

Sherb Bx is a backcrossed Sherbert line, and Sherbert descends from Garlic Mushroom
Cookies and Sunset Sherbet. This is where the creaminess and part of the floral character come from.

Jealousy, also from Seed Junky and Leafly’s Strain of the Year for 2022, contributes
the sharp, almost solvent-like top note and much of the potency. Our
Jealousy guide covers that parent in
detail.

What is unusual here is that every ancestor is a modern commercial success rather than a landrace or a
1990s workhorse. Permanent Marker is the product of about fifteen years of concentrated selection inside
a small circle of American breeders, and it shows in how uniform the plant is.

THC and Terpenes

Reported THC of 25–35% is real, and it matters. At 32% THC a small amount of flower
delivers roughly twice the dose of the same volume at 16%. If you are returning to cannabis after a
break, or your tolerance is low, this is not the strain to reintroduce yourself with. CBD is under 1%.

Individual jars vary within that band, and figures above 35% on a menu should be treated as
batch-specific marketing rather than a property of the genetics.

• Limonene typically leads and supplies the bright, sharp opening.
• Beta-caryophyllene sits underneath and provides the peppery structure that keeps the
  sweetness anchored.
• Linalool is the terpene most responsible for the signature. It is the floral,
  lavender-adjacent compound that turns the profile from fruit into something closer to scented soap or
  marker ink.
• Humulene and myrcene round out the base in most panels.

Total terpene content is frequently high, which is why the smell carries through packaging in a way
most flower does not.

Effects and Experience

Reports describe a fast and forceful onset — euphoric, talkative, sometimes slightly disorienting in
the first ten minutes — that settles into heavy body relaxation over the following half hour. It is not
subtle, and the arrival is quicker than the indica-dominant classification suggests.

At this potency, the standard THC side effects are amplified: dry mouth, dry eyes, and a meaningfully
higher chance of anxiety or paranoia at large doses in sensitive users. That is general cannabis
consumption information, not a medical claim.

The practical advice is unusually important here. One inhalation. Wait a full fifteen minutes. Then
decide. Most bad experiences with Permanent Marker are dosing errors rather than reactions to the
strain.

Where Permanent Marker Shows Up

Permanent Marker is a premium-tier strain, which means availability follows craft cultivation rather
than volume production. California is the deepest market by a wide margin — the
Los Angeles hub covers shopping there, and it is where
most of the licensed material originates.

Colorado’s established craft growers have adopted it widely; see the
Denver hub. Massachusetts is the strongest East Coast market for
it, with several cultivators running it as a flagship — the
Boston hub covers that state.

In smaller markets it appears as a limited drop rather than a standing item, and it sells out quickly
when it does. Because the name carries a premium, it is also one of the most frequently mislabeled
strains on shelves. Menus change daily and we do not track live inventory.

Price Reality

Permanent Marker sits at the top of the flower shelf. In California, well-grown indoor commonly runs
$45–$65 an eighth before tax, and small-batch releases from named cultivators go higher. That is roughly
double the mid-shelf price in the same store.

Colorado and Massachusetts land in a similar band, $45–$60, and the newer East Coast markets can
exceed it. Illinois’s potency-tiered excise tax hits Permanent Marker harder than almost any other
strain precisely because of its THC figures. Michigan is the exception, as always — $25–$40 is common
there.

Hash rosin made from Permanent Marker commonly runs $60–$100 a gram in mature markets. Given the
terpene content, it is one of the strains where that format is genuinely different rather than just more
expensive.

How to Shop It

The smell test is decisive. Real Permanent Marker announces itself through the jar with a sharp,
chemical-floral, almost soapy note. If it smells like generic sweet dessert flower, it is not Permanent
Marker, whatever the label says.

Check total terpene percentage as well as THC. A 27% jar with 3% total terpenes is a better product
than a 33% jar with 1.2%. Our flower guide covers reading the
certificate of analysis properly.

Be careful with Permanent Marker vape cartridges. The signature is the hardest part of the profile to
reconstruct from botanical terpenes, and most distillate carts try. The
vape guide covers what to check before you buy one.

Buy from a licensed store and verify the license on the state regulator’s public search. Premium
strain names attract counterfeit packaging, and a printed bag is not evidence of anything.

Growing Notes

Growers describe Permanent Marker as demanding and worth it: dense, resin-heavy flower with strong
color, and a real need for environmental control because the buds pack tightly. It is not a beginner’s
plant.

Flowering-time and yield figures differ substantially across seed sources and cuts, and a great deal
of material sold under the name has uncertain provenance given how quickly it became valuable. Use the
figures from the nursery or seed bank you are actually buying from.

Comparisons

Against Jealousy, its own parent, Permanent Marker is stronger and far more
chemical-floral. Against Runtz, it is sharper and less candy, with a higher potency
ceiling. Against Wedding Cake, it is louder in every direction. If the soapy note is not
for you, Biscotti gives you the pastry side without the signature; if you want the potency in a more
familiar flavor, the Gelato family is the safer choice.

Availability

We do not maintain live dispensary inventory and menus change daily, so we will not claim a specific
store has Permanent Marker today. Check the retailer’s own menu, or find your market in the
state and city directory.

Frequently Asked Questions

What is Permanent Marker a cross of?

Biscotti and Sherb Bx crossed with Jealousy, bred by JBeezy of Seed Junky Genetics and selected by Doja Pak. Every ancestor in the line is a modern commercial strain rather than a landrace or a 1990s workhorse.

How much THC does Permanent Marker have?

Reported figures run 25–35%, which is genuinely at the top of the commercial range. CBD is under 1%. Menu listings above 35% should be treated as batch-specific marketing rather than typical of the genetics.

Did Permanent Marker win Strain of the Year?

Twice, from two different publications. High Times named it Strain of the Year in late 2022, and Leafly named it Strain of the Year for 2023.

Why is it called Permanent Marker?

Because of the smell. The dominant aroma is a sharp chemical-floral note that reads as permanent marker or scented soap, sitting over gas and a sweet pastry base. Linalool is the terpene most responsible for it.

Is Permanent Marker good for beginners?

No. At 25–35% THC a small amount delivers roughly twice the dose of the same volume of 16% flower. If you are new or returning after a break, start with something in the high teens. This is general consumption information, not medical advice.

What terpenes are in Permanent Marker?

Limonene typically leads with beta-caryophyllene underneath, and linalool supplies the signature soapy-floral note. Humulene and myrcene round out the base. Total terpene content is frequently high, which is why the smell carries through packaging.

How much does Permanent Marker cost?

Commonly $45–$65 an eighth before tax in California, with Colorado and Massachusetts in a similar band and Michigan far cheaper at $25–$40. Illinois’s potency-tiered excise tax hits it harder than most strains because of its THC figures.

How can I tell if Permanent Marker is authentic?

Smell it. Real Permanent Marker announces itself through the jar with a sharp chemical-floral, almost soapy note. Generic sweet dessert flower under the name is mislabeled. Buy licensed and verify the batch certificate of analysis — printed packaging proves nothing.
