More particularly the composition further comprises one or more cannabichromene type compounds. Particularly cannabichromene propyl variant (CBCV) and/or cannabichromene (CBC). More particularly still the composition is absent or substantially absent of other cannabinoids, including in particular tetrahydrocannabinol (THC) and tetrahydrocannabivarin (THCV), which would normally be present in significant amounts in cannabis chemotypes bred to contain a significant amount of CBDV and/or CBD.
