Frequently Asked Questions
In cured cannabis flower, over 90% of THC exists as acidic THCA-A, which decarboxylates into psychoactive Delta-9 THC when heated or vaporized. Reporting Total Stoichiometric THC (Delta-9 THC + THCA x 0.877) ensures accurate member dosing and enforces the statutory 10.0% THC cap for members aged 18 to 21.
Every batch verified under CA-LAB-05 (ISO/IEC 17025 wet lab) or CA-NIR-SYNC (CannaApp Spectral NIR) automatically generates a print-ready 62x100 mm neutral thermal label PDF containing all mandatory Par. 21 fields and a scannable SHA-256 verification QR code.
