Cannabichromene (CBC) is a cannabinoid found in the cannabis plant. It is a non-psychoactive compound, meaning it does not cause a patient to feel "high". CBC has been shown to have anti-inflammatory properties in vitro, which may contribute to cannabis analgesic effects. It has also been found to encourage the human brain to grow by increasing the viability of developing brain cells in a process known as neurogenesis. CBC plays a significant role in the anti-cancer and anti-tumor capabilities of cannabis. CBC battles inflammation by activating the CB2 receptor, but it does not activate CB1, which could enhance its healing potential when combined with cannabinoids that do activate CB1, such as THC. CBC has shown antitumor effects in breast cancer xenoplants in mice and has anticonvulsant activity in a mouse model. In vitro, CBC binds weakly to CB1 and CB2 with binding affinities of 713 nM and 256 nM, respectively, which are significantly lower than that for THC with 35 nM at CB1.
