The reason for the low THC content in hemp is that most THC is formed in resin glands on the buds and flowers of the female cannabis plant. Industrial hemp is not cultivated to produce buds, and therefore lacks the primary component that forms the marijuana high. Furthermore, industrial hemp has higher concentrations of a chemical called Cannabidiol (CBD) that has a negative effect on THC and lessens its psychoactive effects when smoked in conjunction.
Being a hyperaccumulator also has drawbacks: If a hemp plant that is used in production of CBD oil was cultivated in a land that is rich in heavy metals such as mercury and lead, the resulting oils will also reflect the amount of heavy metals absorbed by the plant, making it unsafe for humans to consume, especially children or others who are extremely vulnerable to toxins.
Watch Out For: Companies who won’t disclose their extraction method or utilize hydrocarbons like butane and propane. These substances are toxic in high amounts and even with proper purging, most hydrocarbon extracts contain residual solvent. Other extraction methods do not result in a full spectrum extract – meaning they were not able to extract all of the beneficial compounds from the hemp plant (i.e. you don’t get the full range of benefits).
It sounds like the title of a children’s book, but like so much else that you learned in kindergarten, it’s true. Everyone’s body is different – but everyone’s endocannabinoid system is really unique. For reasons we don’t fully understand, receptors in the endocannabinoid system don’t respond predictably to cannabinoids from person to person. This lack of a predictable response makes standard dosing tricky.
To get almonds from an almond tree, you can just shake the tree. To get juice from an orange, you can simply squeeze the fruit. But getting CBD oil from hemp is a much more complicated process. The cheapest and easiest ways to extract CBD oil from hemp commonly involve harsh solvents that can leave chemical residue in the CBD oil. The best, and most reliable extraction method, uses carbon dioxide (CO2) under high pressure and extremely low temperatures to pull out as much CBD as possible without introducing contaminants. Once the CO2 is no longer under intense pressure, it simply evaporates, leaving virtually no trace of extraction on the CBD oil.
