CBD flower contains odour-affecting chemicals known as terpenes. These are naturally-occurring in both the hemp and marijuana plants (cannabis Sativa). However, different strains of CBD flower will contain different terpenes, and as such, the strength of the smell will vary from strain to strain. Despite the differences in composition between CBD/Hemp flower and THC-rich marijuana, their smell may be relatively similar. The smell and taste tend to be described as “earthy” or “skunky”.
