One might expect anything contained in a Hemp plant to also be in any extract from that plant but owing to the fact that contaminants are not stored equally around the parts of the plant, it is frustrating that the article does not tell us which parts of the hemp were used to extract the CBD or what kind of Hemp was used. If it was Industrial hemp, the extract would have been sourced from the absorbent leaves. This is because Industrial Hemp is usually male and the sparse male flowers contain little CBD if any. In fact the leaves of even high grade cannabinoid rich Cannabis plants typically contain little CBD in the shade leaves so you would need a lot of processing and a lot of leaves to obtain a useful amount of CBD. If copious quantities of highly absorbent leaves of Industrial hemp were used, then very likely the results would show significant amounts of toxic contamination. So, was the CBD from the leaves of low quality Industrial Hemp or high quality, high resin Cannabis buds used in this experiment? Clearly this is an area that would benefit from a great deal more published research. It would be useful to know just how much, if any, heavy metal contamination is typically in the resin of the buds of contaminated plants. Unfortunately, I could find nothing on that subject. One also becomes aware that these types of articles by accredited companies and researchers always seem to promote the argument, directly or indirectly, that CBD should become the exclusive property of the pharmaceutical industry so that any inherent dangers, real or otherwise, might be eliminated. This one proved to be no exception. The other responsible path to take would be to educate the consumer who can then make rational choices based on solid research. That is, research that includes the examination of obvious, albeit inconvenient variables.

As mentioned, the cannabinoids THC and CBD in hemp are found mainly in the sticky resin that is exuded from the female buds of Hemp/Cannabis. These and other important cannabinoids, terpenes and flavinoids vary greatly in their ratios and quantities from strain to strain. Growing conditions are also a very important factor in determining the ratios of CBD and THC in any given plant. THC (the stuff that makes you high) is present to some degree in all female Cannabis flowers but some strains are specially developed so that THC content remains low but the CBD content is high. The strains that produce a higher concentration of THC than 0.3% in their raw state have been exotically dubbed “Marijuana” by federal law in the United States, such, “Marijuana” is illegal to grow or use in the UK. Also the parts of the plant containing the highest concentrations of THC like the flowers and trim leaves in a female plant can be grouped as “Marijuana” even if the rest of the plant is classed as common, legally permitted, “Hemp”.
