However, health advocates, scientists, and doctors agree that CBD oil offers all of the profound benefits of THC and Cannabis oil – and more – but without the negative side effects. Consumers, too, become advocates of CBD oil for its health benefits once they try it, and it’s easy to see why. Not only do they enjoy it as an alternative natural therapy, but have peace of mind that it’s perfectly legal. Likewise, many people report suffering from anxiety, panic attacks, and paranoia when they first use Tetrahydrocannabinol oil, while they report that CBD oil has a calming and soothing nature.
Cannabidiol offers a novel pharmacodynamic profile as an anxiolytic agent. It is believed that administration of CBD (cannabidiol) modulates neurotransmission in a multitude of ways. Literature shows that cannabidiol alters 5-HT1A, GPR55, CB1/CB2, and mu/delta opioid receptor sites – while simultaneously enhances hippocampal neurogenesis. The combination of these neurophysiological effects likely contribute to its efficacy as a novel anxiolytic.
It's also safe to take up to 1,500 milligrams of CBD, according to a study published in Neurotherapeutics, which means there's not much risk—and maybe a fair amount to gain—in dosing yourself before bed. So over the course of two weeks, I experimented with four different kinds of CBD to see how it would affect my sleep. I took each one at the same time each night and each type for three nights. Here's what went down:
Relevant studies are summarized in Table Table2.2. The anxiolytic effects of CBD in humans were first demonstrated in the context of reversing the anxiogenic effects of THC. CBD reduced THC-induced anxiety when administered simultaneously with this agent, but had no effect on baseline anxiety when administered alone [99, 100]. Further studies using higher doses supported a lack of anxiolytic effects at baseline [101, 107]. By contrast, CBD potently reduces experimentally induced anxiety or fear. CBD reduced anxiety associated with a simulated public speaking test in healthy subjects, and in subjects with SAD, showing a comparable efficacy to ipsapirone (a 5-HT1AR agonist) or diazepam [98, 105]. CBD also reduced the presumed anticipatory anxiety associated with undergoing a single-photon emission computed tomography (SPECT) imaging procedure, in both healthy and SAD subjects [102, 104]. Finally, CBD enhanced extinction of fear memories in healthy volunteers: specifically, inhaled CBD administered prior to or after extinction training in a contextual fear conditioning paradigm led to a trend-level enhancement in the reduction of skin conductance response during reinstatement, and a significant reduction in expectancy (of shock) ratings during reinstatement .
Earlier preclinical studies have suggested that the therapeutic effects of CBD might depend on the presence of specific clinical conditions. As an example, Campos et al. (2013) showed that the chronic use of CBD for 2 weeks, while not directly increasing hippocampal neurogenesis, prevented its decrease by unpredictable chronic stress. Thus, the absence of changes in the sleep of healthy volunteers treated with CDB in our study should not be considered as a final indication that CBD could not have positive effects in patients with sleep disorders.
This is a topic I am asked about all the time, and have been for years: how does cannabis help sleep and health? I’ve heard that the number-two reason why people smoke or use cannabis is for sleep. Considering the recent passing of the recreational use of cannabis in California and other several states I think it is high time (pun intended!) to look at understanding CBD, one of the most active ingredients in medical cannabis.
Bioavailability: The bioavailability of orally-administered CBD is considered extremely low (around 6%). If you smoke cannabidiol, the bioavailability increases to over 30% and if you utilize an intranasal preparation, bioavailability may reach nearly 50%. However, since many people are using oral preparations of CBD, the bioavailability is low and will require a high dose.
CBD exerts several actions in the brain that explain why it could be effective in treating anxiety. Before we dive in, it’s important to note that most research describing how CBD works is preclinical and based on animal studies. As the saying goes, “mice are not men” — and, results from animal studies don’t always neatly transfer to human therapies. However, preclinical studies provide insights that move us in the right direction:
The consequences of sleep deficiency include multiple adverse outcomes. You can expect deterioration in all aspects of your health and wellbeing. Lack of sleep and/or poor-quality sleep will age you prematurely, compromise your decision making, dramatically decrease your athletic performance, and increase the risk of injury. Alcohol or drug-induced sleep is not the healthy, restorative sleep the mind and body needs either.
There may be some drawbacks associated with using CBD oil for anxiety, especially over a long-term. Hypothetical drawbacks could result from CBD usage include: deleterious epigenetic and/or neurophysiological effects, increased anxiety, tolerance onset (with decreased efficacy over time), and/or withdrawal symptoms. Keep in mind that many of these drawbacks are merely speculative and cannot be confirmed.
A review published in 2017 in the journal Frontiers in Pharmacology described how CBD may work to protect the hippocampus — the part of the brain responsible for several important functions, such as learning, memory and navigation — during times of stress, and may also help prevent brain-cell destruction that results from schizophrenia. Another 2017 review published in the journal Annals of Palliative Medicine summarized a handful of studies that suggest cannabis oils containing THC or CBD, or both, may help with chronic pain management, but the mechanism is unclear.
