Put the Terps on the Website

Every cannabis product in NJ goes through a lab that tests 40+ data points. Dispensary menus show 4. We publish the rest.

Every cannabis product sold in New Jersey goes through a lab. The lab tests for 7 to 12 terpenes, a full panel of cannabinoids, pesticides, heavy metals, and moisture content. That data gets filed with the state through Metrc, the seed-to-sale tracking system every licensed dispensary is required to use.

Then you visit the dispensary website, and it shows you this:

That’s it. Four data points from a test that produced forty.

The lab report for that same batch shows beta-myrcene at 0.38% (associated with body relaxation), the pinene complex at 0.44% combined (linked to alertness and mental clarity), and beta-caryophyllene at 0.22% (the only terpene that binds directly to CB2 receptors, associated with anti-inflammatory effects). Total terpene content: 1.88%. CBGa at 1.77%, above the 90th percentile in our database of 373 lab profiles. Most menus don’t surface any cannabinoid beyond THC.

The dispensary has this data. So does the state. You’re the only one in the transaction who doesn’t.

”Indica” told me nothing. The terpenes told me everything.

Brownie Scout is labeled indica. Every dispensary menu says so. Indica means sedation, couch, sleep. That’s what the label promises.

I use Brownie Scout to work. All day. Focus, energy, productivity. According to the label, that shouldn’t happen.

The lab report explains why it does. Brownie Scout’s dominant terpene across 33 tested batches is limonene, approaching 1% in some harvests, associated with mood elevation and stress relief. It also has pinene, linked to alertness and mental clarity. Yes, it has myrcene too (body calm), but limonene is the lead. Based on the terpene profile, you’d expect a functional, mood-forward experience. The “indica” label predicts a nap.

That’s one strain. The data across 49 tells the same story in different proportions.

A 2022 study published in PLOS ONE analyzed 89,923 cannabis samples and found that indica and sativa labels do not reliably predict chemical composition. A strain labeled indica can have the same terpene profile as one labeled sativa. The labels originally described how the plant grows (historically, short and bushy vs tall and thin), not what it does to you. Modern cannabis is so hybridized that even those morphological distinctions barely hold. The industry kept the labels because consumers learned them first, and changing vocabulary is harder than changing a menu.

Terpenes are the vocabulary that should have replaced indica and sativa years ago. The data exists. The research backs it up. The labels on the menu are the thing that’s wrong.

Same name, five different products

A dispensary might list “Brownie Scout” in four places on its menu: flower, live resin cart, live rosin, and a concentrate. Same strain name. The chemistry is not the same.

Brownie Scout
Same strain. Different chemistry.
Flower
1.88%
Live Resin Concentrate
5.33%
Live Rosin
6.33%
Limonene Myrcene Pinene Caryophyllene Linalool

The extraction process changes which terpenes survive and at what concentration. Live rosin (solventless, ice-water extracted) preserves more of the original plant chemistry. Live resin (hydrocarbon extracted) captures a different profile. Distillate strips the terpenes out entirely and adds them back from a bottle. These are different products wearing the same strain name.

Even within flower, different harvests produce different chemistry.

Brownie Scout Flower 3.5g
Same strain. Same grower. Different harvests.
Batch A
1.77%
CBGa
90th percentile
Batch B
2.40%
CBGa
36% higher

Same strain, same grower, same product type, 36% more CBGa. CBGa is the acidic precursor to CBG, a cannabinoid that early research associates with anti-inflammatory and neuroprotective properties. Brownie Scout tests above the 90th percentile for CBGa in 28 of 33 batches. No dispensary menu in NJ surfaces CBGa.

The menu is a nutrition label with only the calories

Imagine buying wine and the bottle said “Red. 13.5% alcohol.” No grape variety, no region, no vintage. You’d pick by price and label art. That’s how most people shop for cannabis right now.

THC percentage tells you potency the way alcohol percentage tells you strength. It says nothing about the experience. Two strains at 24% THC can feel completely different because their terpene profiles are different. One is 2% myrcene (body, sedation, couch). The other is 1.5% terpinolene (head, energy, focus). Same THC, completely different experiences, because the terpenes are different.

The industry knows this. Rythm prints terpene ratios on their packaging. Dispensary POS systems store the data in their product databases. The information exists at every step of the supply chain. It stops before it reaches you.

Why it stays hidden

Nobody is hiding this on purpose. Dispensary menus were designed before terpene data mattered to consumers, and nobody went back to change them.

Menus are built for speed: name, type, THC, price. Most POS platforms don’t surface terpene data in their default views even when the data is in the system. Dutchie’s API has a terpene array for every product that supports it. The data is one toggle away. The path of least resistance is to leave it out, and the path of least resistance also happens to be good for business when consumers can’t comparison-shop on chemistry.

The result is a $4 billion legal NJ cannabis market where consumers pick products based on strain name recognition, THC percentage, and price, which happen to be the least informative data points in the lab report.

What the data looks like when someone publishes it

We track 49 Rythm strains across 206 NJ dispensaries. We’ve collected 373 lab-verified terpene profiles from Certificates of Analysis.

4.6% terpinolene, more than 10x the average across our database. Terpinolene-dominant strains are rare in NJ. Users describe them as heady and uplifting, and this strain is chemically distinct from almost everything else on NJ shelves. No dispensary menu tells you this.

Garlic Jam

Had 2.08% myrcene and 1.30% limonene. Past tense. It’s gone from every NJ dispensary we track. That terpene profile no longer exists in the state’s Rythm supply. If it was your favorite, you didn’t get a warning. It disappeared from the menu.

71 community reviews across YouTube and Leafly and one lab test in our database. The most talked-about strain is the least verified. The reviewers don’t have chemistry data, and the labs don’t read Reddit.

704,000 stock checks later

Since March 28, we’ve checked NJ dispensary inventory 704,140 times. We track which stores carry which strains and what they charge. We measure how fast products sell out and when restocks land. We grade rarity against 89,000 lab-tested samples and flag strains when they start disappearing from shelves.

None of this data is proprietary. All of it comes from public lab reports, public dispensary menus, and public product listings. We collect it, verify it, and publish it. Because someone should.

What we think should change

Every dispensary menu should show terpenes and total terpene percentage alongside THC. The compounds and their concentrations: Limonene 1.3%. Myrcene 0.8%. A 3% total terp flower is a different product than a 1% total terp flower at the same THC. That single number helps more than any marketing copy on the label.

Until dispensaries do this, Terpmon will. Every strain profile, every batch, every terpene percentage is at terpmon.com.
