CBC

Cannabichromene (CBC) is one of the six major cannabinoids produced by cannabis plants, typically accounting for 0.1-0.5% of the total cannabinoid content [1]. Unlike THC, CBC is completely non-psychoactive — it doesn't bind effectively to CB1 receptors in the brain. Structurally, CBC shares the same molecular formula as THC and CBD (C21H30O2) but has a different arrangement that gives it distinct biological properties.

CBC forms through the same initial pathway as THC and CBD, starting from cannabigerolic acid (CBGA). The enzyme CBCA synthase converts CBGA into cannabichromenic acid (CBCA), which then decarboxylates into CBC when exposed to heat or UV light [2]. This is why CBC levels tend to be higher in sun-dried cannabis compared to indoor-grown varieties.

Beyond cannabis, CBC-like compounds haven't been identified in other plants, making it relatively unique to the Cannabis genus. However, CBC shares structural similarities with other naturally occurring chromenes found in essential oils of plants like Helichrysum italicum, though these are distinct molecules with different effects [3].
