As Kane leads me around his lab, I see the excitement on his face and on the faces of his young staff. The place feels almost like a start-up company. “So much of science is incremental,” he says, “but with this cannabis work, the science will not be incremental. It will be transformative. Transformative not just in our understanding of the plant but also of ourselves—our brains, our neurology, our psychology. Transformative in terms of the biochemistry of its compounds. Transformative in terms of its impact across several different industries, including medicine, agriculture, and biofuels. It may even transform part of our diet—hemp seed is known to be a ready source of a very healthy, protein-rich oil.”
Hippocampal neurogenesis: The hippocampus is a major brain area, and plays a critical role in a variety of brain functions. It’s most famous for its role in memory formation and cognition. Brain scans of patients suffering from depression or anxiety often show a smaller hippocampus, and successful treatment of depression is associated with the birth of new neurons (neurogenesis) in the hippocampus.
Research works in this aspect are inclining in the favor of CBD for alleviation of insomnia. For example, a study carried out in the year 2006 revealed that cannabidiol (CBD), which is the second important constituent of cannabis, and is non-psychoactive in nature, may have an impact on the sleep mechanism of rats. It was shown to increase alertness with light, and had no particular impact on sleep with the lights off. This provides an insight that CBD could be brought into use for therapeutic relief of day-time somnolence, and hence, can this way improve night-time sleep.
Cannabidiol (CBD) is just one of over 85 scientifically-identified cannabinoids (or chemical compounds) derived from the flowering plant cannabis. Each of the cannabinoids within cannabis elicit unique neurophysiological effects. Most people are well-aware of THC (tetrahydrocannabinol), the predominant cannabinoid within cannabis that is ingested by upwards of 230 million people per year as a psychoactive euphoriant.
He was using an oil from a brand called Pure Kana, and the only thing that I had known about the stuff before I tried it was that it wasn’t supposed to get you high. (In fact, I really think the main reason I willingly tried it was because I knew that my aunt – who works full time and supports three daughters – was using it. I figure if she was into it, then it must be halfway legit).
My grandson has severe anxiety. His anxiety and meltdowns were so severe that we couldn’t go shopping, out to eat, or anything else normal people do. The medicines his doctors put him on have horrible side effects. We started him on the cbd oil once a day. Within a couple weeks we saw a huge difference. Yes, he still has some anxiety, and meltdowns, but nothing like they were. We can actually go you the grocery store with him now! And it’s not a coincidence because when we run out for a few days we can see the difference! – Dian
Human activities—including pollution, deforestation, overpopulation, poaching, warming oceans and extreme weather events tied to climate change—are predicted to drive so many mammals to extinction in the next five decades that nature will need somewhere between 3 to 7 million years to restore biodiversity levels to where it was before modern humans evolved, according to an alarming new analysis published Monday in the Proceedings of the National Academy of Sciences.
Although some studies have demonstrated the potential effect of CBD on sleep behavior, research about the effects of CBD on the slow wave sleep (SWS) of humans with regular sleep is still lacking. The impact of CBD on sleep, possible side-effects or the advantages of lack of them, including objective measures through polysomnography, has not yet been investigated. Thus, the objective of the present study was to assess the effect of the acute administration of an anxiolytic dose (300 mg, Zuardi et al., 1993, 2017) of CBD on sleep in healthy volunteers by means of cognitive and subjective measures and polysomnography exams.
Just like THC, CBD is a chemical compound extracted from hemp plants. Both hemp and cannabis contain cannabidiol (CBD), the non-psychoactive substance. THC, however, is the substance that gives users that “high” or psychoactive effect. CBD has many similarities to THC when it comes to potential health benefits, but the main difference is that it’s a non-psychoactive substance, so it doesn’t give a natural high to users. It also does not cause anxiety, paranoia, or the mouth and eye dryness associated with THC, even when CBD is consumed in higher concentrations. Due to these inherent advantages, most high-quality CBD oil products on the market today are extracted from the hemp plant. THC oil, on the other hand, is derived from the cannabis plant, so it contains high levels of THC and low levels of CBD. On the other hand, industrially produced hemp contains higher concentrations of CBD with only trace amounts of THC, so it’s safer and offers fewer symptoms for users.
“These studies mainly point to CBD’s ability to interact with ... serotonin receptors and GABA receptors in the brain,” she explained. “Serotonin plays an important role in mood and anxiety, and GABA is known as the main ‘inhibitory’ neurotransmitter, meaning it calms excess activity in the brain and promotes relaxation. GABA receptors are the target of benzodiazepines, which are a class of anti-anxiety drugs.”
Neurologists are skilled at predicting side effects and interactions between well-researched pharmaceuticals. But due to the dearth of reliable research about CBD, doctors like Hernandez and Knupp cannot guide their patients in its use. If there are adverse reactions, Penny will find out because Harper will suffer through them. She has had to figure out through trial and error how best to mix and measure Harper’s oils. The bottom line, Penny said, is simple: “We are the research.”
The following instruments were used: (a) Visual Analog Mood Scale – VAMS (Norris, 1971); (b) State-Trait Anxiety Inventory – STAI (Spielberger et al., 1970), translated and adapted to Brazilian Portuguese by Gorenstein and Andrade (1996); (c) Epworth Sleepiness Scale – ESS (Johns, 1991); (d) Pittsburgh Sleep Quality Index – PSQI (Buysse et al., 1989); (e) digit symbol substitution and symbol copying tests of the Wechsler (1955) Adult Intelligence Scale – WAIS; and (f) Psychomotor Vigilance Test – PVT (Graw et al., 2004; as made available by the National Center on Sleep Disorders Research).
Cannabidiol’s anti-anxiety (Zuardi et al., 1993, 2017; Crippa et al., 2009; Bergamaschi et al., 2011b) and antidepressant (Saito et al., 2010; Zanelati et al., 2010) potential seems to differ from other drugs with effects on the central nervous system, since we found no alterations in sleep architecture. Additionally, studies on the anxiolytic, antipsychotic and antiparkinson effects of CBD described no sedation or drowsiness side effects in their volunteers (Zuardi et al., 1993; Crippa et al., 2004; Fusar-Poli et al., 2009; Chagas et al., 2014a). These findings complement the literature on the few significant side effects resulting from the administration of CBD to humans in a wide range of doses, administered chronically or acutely (Bergamaschi et al., 2011b; Kerstin and Grotenhermen, 2017). It seems, therefore, that CBD has an adequate safety profile with good tolerability and does not affect psychomotricity or cognition (Hayakawa et al., 2007; Crippa et al., 2010; Bergamaschi et al., 2011b; Kerstin and Grotenhermen, 2017). This is particularly important in Parkinson’s disease, where motor and cognitive symptoms play a central role.
The side effects and risks involved with consuming marijuana-based products aren't clear, either, Bonn-Miller said. It's important to "determine cannabinoids that are useful therapeutically while understanding and using cannabinoids that are associated with less risk," he said. At least with CBD, he said, it doesn't appear to have the potential for addiction. That's different from THC, which has been associated with addiction, he said, and negative side effects, including acute anxiety.
