Verifiable product data for South African leaf.

A public registry for cultivar identity, batch laboratory data, and farm origin — covering cannabis cultivars (cannabinoid & terpene profiles) and tobacco cultivars (nicotine assay, residue panels, TSNAs). One trust rail between cultivators, growers, retailers, and customers.

Cultivators & growers

Own your story beyond the shelf.

Register each cultivar once, whether cannabis or tobacco. Every batch carries a QR to its product page — chemistry profile, COA, cultivar genealogy, farm origin — no matter which dispensary, pharmacy, or tobacconist sells it.

Retailers

Give customers real answers.

Scan a cheekyleaf QR at the counter to read full product detail in seconds. Works the same for cannabis and tobacco product pages. Overlay your own retail intel onto supplier product pages for your store's catalogue.

Customers & patients

Know what you are buying.

Scan once and see what your product actually contains — for cannabis: cannabinoid %, terpenes, farm origin. For tobacco: nicotine, residues, TSNAs, farm origin. Lab certificate either side. No marketing copy, only verifiable data.

What you will find on a cheekyleaf product page

Cannabis: Cannabinoid profile (THC, CBD, CBG, THCV percentages) displayed as bars, not prose
Cannabis: Terpene profile (myrcene, limonene, pinene, linalool, caryophyllene, humulene, terpinolene) as a radar chart
Tobacco: Nicotine assay, pesticide residue panel, heavy metals (cadmium, arsenic, lead), tobacco-specific nitrosamines (NNN, NNK), mycotoxins, curing method
Downloadable Certificate of Analysis for the exact batch (both leaves)
Cultivar genealogy and farm origin with photos and cultivator bios
Harvest date, lot number, batch ID, non-irradiated status (cannabis), curing date (tobacco)
Supplier-written usage notes in neutral factual language
Peer-reviewed academic references where applicable
Multilingual where the market demands it — English and German at launch

Sample cultivar page

See what a cheekyleaf product page looks like.

We've compiled a worked example for the Bliss cultivar (Girl Scout Cookies × Tangie) from published literature — terpene radar, cannabinoid profile, parent chemistry, academic references, EN/DE languages. Real batch data replaces the example on supplier onboarding.

First product on the rail

Mostly Rollie's — a Cheekyleaf concept.

The first commercial product designed from day one to ride the Cheekyleaf rail. A prescription-grade cannabis-tobacco cigarette where every pack traces upstream to its cannabis cultivar batch and its tobacco cultivar batch — both credentialed here.

Mostly Rollie's proves the registry's commercial value. The rail is bigger than the product: open to any cultivator or grower of cannabis or tobacco.
