A study performed at the Italian Piemonte University and published in 2008 implied that all cannabinoids help the immune system to fight bacteria. Especially potent are five cannabinoids (including CBD), with the study focusing on antibiotic-resistant strains of the Staphylococcus Aureus, a relevant example of the antibiotics abuse the last few decades have witnessed.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
The immediate and powerful effects of THC are explained because of the special affinity it has with the CB1 type receptors, which mediate crucial processes in the brain. The less prominent (but no less important) action of CBD was explained, at least for a while, by hypothesizing that it binds to CB2 type receptors, hence its more diffuse manner of exercising changes in the body. Early on, the antipsychotic effects of cannabidiol were observed, an aspect which seemed to be in consonance with this initial hypothesis.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases.
'If you have a health condition, or are taking any prescribed or over-the-counter medicines, always check with your doctor or a pharmacist for possible drug supplement interactions before taking CBD,' says Dr Brewer. 'This is because CBD interacts with enzymes involved in metabolising some medicines and may result in increased drug levels that could cause side effects.
