THCa (Tetrahydrocannabinolic Acid) is the raw, non-psychoactive precursor to THC. When heated (smoked or vaped), THCa converts into Delta-9 THC through a process called decarboxylation.
THCp (Tetrahydrocannabiphorol) is a naturally occurring cannabinoid known for its strong binding affinity to CB1 receptors, which may result in more potent effects compared to traditional Delta-9 THC.
As with all cannabinoids, effects vary by individual tolerance and body chemistry.
