THC and CBD levels, of course, are the main drivers of the pharmacological activity. That's what we label for medical cannabis at this point.
Other aspects would be the terpenes I referred to before, so those would be the smell and flavour components. One can see that labelling might, in a limited way—because we don't want to get into a list of a hundred chemicals that have to be parsed by a consumer—give us some information around the terpene composition of the product.
There are also other cannabinoids also present. THC and CBD are the two main ones, but we often see large amounts of cannabigerol, CBG, or cannabichromene, CBC. I would suggest also including information on the presence of some of the other cannabinoids that in certain products might be higher than a baseline.
There is also this whole focus in the cannabis world on strains and genetics and the origin of the material. There is a widespread classification between sativa-type plants and indica-type plants, which hasn't really stood up to scientific scrutiny at this point, but there could be labelling around the sort of genetic type of plant as well.
