Dr. Ethan Russo, medical director at Phytecs, a biotechnology company spearheading research into plant- based medicines and the endocannabinoid system, took issue with Titus’s claim, however. “Bioaccumulators can recruit heavy metals from the soil,” Russo said, “but breaking them down would be alchemy.” Government regulation of the pharmaceutical industry is designed to protect consumers from unfounded scientific claims.
Anxiolytic effects of CBD in models of generalized anxiety have been linked to specific receptor mechanisms and brain regions. The midbrain dorsal periaqueductal gray (DPAG) is integral to anxiety, orchestrating autonomic and behavioral responses to threat , and DPAG stimulation in humans produces feelings of intense distress and dread . Microinjection of CBD into the DPAG produced anxiolytic effects in the EPM, VGC, and ETM that were partially mediated by activation of 5-HT1ARs but not by CB1Rs [65, 68]. The bed nucleus of the stria terminalis (BNST) serves as a principal output structure of the amygdaloid complex to coordinate sustained fear responses, relevant to anxiety . Anxiolytic effects of CBD in the EPM and VCT occurred upon microinjection into the BNST, where they depended on 5-HT1AR activation , and also upon microinjection into the central nucleus of the amygdala . In the prelimbic cortex, which drives expression of fear responses via connections with the amygdala , CBD had more complex effects: in unstressed rats, CBD was anxiogenic in the EPM, partially via 5-HT1AR receptor activation; however, following acute restraint stress, CBD was anxiolytic . Finally, the anxiolytic effects of systemic CBD partially depended on GABAA receptor activation in the EPM model but not in the VCT model [61, 62].
Evidence from human studies strongly supports the potential for CBD as a treatment for anxiety disorders: at oral doses ranging from 300 to 600 mg, CBD reduces experimentally induced anxiety in healthy controls, without affecting baseline anxiety levels, and reduces anxiety in patients with SAD. Limited results in healthy subjects also support the efficacy of CBD in acutely enhancing fear extinction, suggesting potential for the treatment of PTSD, or for enhancing cognitive behavioral therapy. Neuroimaging findings provide evidence of neurobiological targets that may underlie CBD’s anxiolytic effects, including reduced amygdala activation and altered medial prefrontal amygdala connectivity, although current findings are limited by small sample sizes, and a lack of independent replication. Further studies are also required to establish whether chronic, in addition to acute CBD dosing is anxiolytic in human. Also, clinical findings are currently limited to SAD, whereas preclinical evidence suggests CBD’s potential to treat multiple symptom domains relevant to GAD, PD, and, particularly, PTSD.
It also is distinct from THC which acts as a CB1/CB2 partial agonist, thereby stimulating the receptor sites. If it acted the same as THC at the CB1/CB2 receptor sites, its therapeutic potential may be reduced. Moreover, since cannabidiol acts as an inverse agonist at the CB1/CB2 receptor sites, it doesn’t induce psychological euphoria and/or pleasure associated with downstream dopaminergic enhancement in the mesolimbic pathway (resulting from CB1/CB2 agonism).
I didn’t use the oil again until maybe about a week later, and I tried the next time around to really gauge when the effects started settling in. I was using the 300 mg bottle (30 mL), which I think is their lowest potency oil (they also had a 600 mg oil and a 1000 mg oil the last time I checked). It seemed to me that I noticed an obvious anxiety relief in less than an hour – maybe about 45 minutes, if I had to take a guess.
If you’re like me, I think you’ll agree with me when I say that lack of sleep really interrupts your life. You can become cranky and irritable, snapping at friends and colleagues while your body is screaming for rest. Maybe you’ve gone down the laundry list of “fixes” — meditation, yoga, alcohol, exercise, an electronics detox before bed, you know the drill— but nothing seems to be working. It can be frustrating beyond measure.
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.
“I just felt good,” he adds. “But I wasn’t high at all.” Joliat’s anecdotal experience with CBD is a common one. Some informal polling suggests a lot of people today are at least vaguely familiar with cannabidiol, and have either used it themselves or know someone who has. But even some people who use it don’t seem to know exactly what it is or whether there’s any hard science out there to back up its benefits.
