What Is THCA?
 

THCA (tetrahydrocannabinolic acid) is the raw, acidic form of THC found in the living cannabis plant. On its own it is non-intoxicating — but the moment heat is applied through smoking, vaping, or dabbing, it converts into active Delta-9 THC through a process called decarboxylation. The result is the full cannabis experience, from a hemp-derived, Farm Bill compliant product.

GreenRX™ carries THCA flower, prerolls, dabs, and vapes — all third-party lab tested and available in store at 815 Phillips Blvd. Check our Product Labs page for current COAs.
