Runtz, now out with Dispensary Grade Hemp THC products. The official Runtz THCH was created for consumers with experience and high tolerance. THCH collection features proprietary flavor profiles crafted using Live Resin terpenes. Tetrahydrocannabihexol (THCh) has a 6-carbon sidechain and is known to be 10 times stronger than THC. What’s important to understand is that most cannabinoids only have a 5-carbon sidechain in their chemical structures. The greater a sidechain in a cannabinoid is the more potent it becomes.
