Thank you for your questions. Marijuana and hemp are two extremely different strains of the same cannabis sativa plant that have been bred over thousands of years to have entirely different purposes. (Hemp is not the male version of the marijuana plant.) They both contain CBD. Hemp only contains CBD whereas marijuana contains CBD and perhaps a hundred or so other chemicals with a variety of functions, such as THC, the molecule that makes people “high”. Any medicine can have different effects on different people. For example, Benadryl makes some people sleepy yet can make others wide-awake. So, it is not inconsistent for a particular medicine to cause a symptom in one person and to help alleviate it in another. So while many people experience relaxation with CBD, so people do experience the “paradoxical” effect of irritability.
A complicated question. Only CBD oil sold by MMPR registered companies is legal for sale inside of Canada. However, this oil is often in low supply and of low quality due to inexperience and a heavily over-regulated federal system that is not conducive to the production of good product at a decent price. Funnily enough, the companies with the most experience and best track record for making quality CBD oil have been those selling their product in Canada’s “grey area” dispensary market, as they have been doing so for over a decade while the federal program has only been allowed to sell concentrates for the passed year.
Furthermore, a study published in the Journal of Neuroendocrinology has suggested that the ECS is capable of stimulating specific areas of the body involved in metabolism, such as the skeletal muscles and GI tract. This happens due to the presence of anandamide and 2-AG, which are two naturally-occurring compounds in the body that interact with the CB1 and CB2 receptors.
All in all, current research shows us that we will experience the most significant degree of therapeutic relief when all the cannabinoids and the terpenes — essential oils that produce the plant’s aromas — are in the oil. Even adding just a little THC in CBD oil can greatly improve the medical properties because of the phenomenon known as the entourage effect.
