THCA (tetrahydrocannabinolic acid) is a precursor to THC (tetrahydrocannabinol) and is not typically used as a strain for pain relief. In contrast, CBD (cannabidiol) is a different cannabinoid with potential analgesic properties and is often sought after for pain management without the psychoactive effects associated with THC.
It's important to distinguish between THCA and CBD. If you're looking for a strain to help with pain, you should focus on strains high in CBD rather than THCA. As with any cannabis product, consult with a healthcare professional or a knowledgeable budtender for guidance on selecting the right strain and product for your specific pain needs.
