THCP, short for tetrahydrocannabiphorol, is a cannabinoid that researchers first described in 2019. It occurs naturally in cannabis, but only in very small amounts, so products that advertise THCP usually contain THCP that was made or concentrated in a lab.
What makes THCP interesting is its structure. It has a longer "side chain" than regular THC. In laboratory studies, that longer chain allowed it to bind to the CB1 receptor much more strongly than delta-9 THC. That has led to marketing that calls THCP "stronger" than THC.
The honest answer is that research in people is very limited. Lab binding results do not tell us exactly how a product will feel, how much is safe or how it interacts with other compounds. Treat THCP products as potentially strong and unpredictable.
If you come across a product with THCP, read the label carefully for milligrams per serving, check the certificate of analysis to confirm what is actually in it, and start with a very small amount. Do not drive after use.
Availability depends on our regulator's rules, so check the menu or call to confirm before making a trip for a specific product.
