The escalating outbreak of the coronavirus has created a perfect storm for anxiety, isolation, and depression in our communities. Identifying constructive ways to address these mental health challenges is important not just for short-term health, but for long-term health as well.
Cannabidiol (CBD) oil has become increasingly popular in India and worldwide, especially throughout the 2020 health crisis caused by the spread of novel coronavirus. The non-intoxicating marijuana extract is credited with successfully treating symptoms associated with a wide variety of medical problems including anxiety and inflammation.
CBD oil and related products are advertised as containing CBD from hemp, defined in NDPS Act as cannabis plants that contain 0.3 percent or less of psychoactive compound THC. CBD doesn’t produce a high, and consumers swear it helps with aches and pains, anxiety, and other ailments such as sleeplessness.
But Is It Safe & Effective?
Yes, cannabinoids have immunomodulatory effects. This means that they can restore balance to the immune system. If there is too much or too little of an inflammatory response, cannabinoids can help keep this to a happy medium. This does not mean that cannabinoids can beat viral infections.
For a report published in the journal Neurotherapeutics in 2015, scientists analyzed this preliminary research and found that CBD oil shows promise in the acute treatment of conditions like generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder.
Social Anxiety Study
While there’s currently a lack of large-scale clinical trials testing the use of CBD oil in the treatment of anxiety, a small study published in Neuropsychopharmacology in 2011 determined that CBD may help alleviate social anxiety.
For this study, 24 people with social anxiety disorder received either 600 milligrams (mg) of CBD or a placebo an hour and a half before performing a simulated public speaking test. Additionally, 12 other people with social anxiety disorder performed the same test without receiving any CBD treatment.
Results revealed that pre-treatment with CBD significantly reduced anxiety, cognitive impairment, and discomfort while participants were delivering their speech.
One investigation found that, compared with a placebo, a CBD dosage of 160 milligrams (mg) increased sleep duration. The researchers also concluded that the placebo, 5 mg of the insomnia drug nitrazepam, and 40, 80, and 160 mg of CBD helped the participants fall asleep.
Levels of cortisol, the stress hormone, typically peak in the morning, but people with insomniamay have high cortisol levels at night. Independent of insomnia, having high cortisol levels at night is associated with an increased number of nighttime awakenings.
In one study on the effects of CBD, researchers found that cortisol levels decreased more significantly when participants took 300 or 600 mg of CBD oil. These results suggest that CBD affects the release of cortisol, possibly acting as a sedative.
A more recent analysis of CBD and sleep recruited 103 participants who had anxiety or poor sleep. The researchers studied the effects of CBD combined with those of other prescribed medications.
Many people still believe that depression is caused by a chemical imbalance — a serotonin deficiency. But this is a myth perpetuated by pharmaceutical advertisements. Serotonin is definitely part of the big picture — but the verdict is still out about who could use more or less serotonin, and depression is linked to many other neurotransmitter imbalances.
Furthermore, depression is also connected to conditions like inflammation and the structural brain changes resulting from trauma or chronic stress — all of which could be the real cause of the imbalances. Ultimately, there are a wide net of influences contributing to whether or not a person gets trapped by depression, including:
- Physical illness
- Chronic stress
- Stressful life events
- Past trauma
- Physical pain
- Social isolation
- Other emotional disorders
According to researchers, the major reason it works for seizures is that CBD protects neurons in the hippocampus — the exact brain area that is atrophied in depressed people — and there’s interesting evidence from both animal and human research:
- Rodent Evidence:In epileptic rats, CBD treatments reduce neuron atrophy and death in the hippocampus.
- Human Evidence:Like depressed people, chronic users of THC tend to have a smaller hippocampus, but CBD (in higher-CBD cannabis) helps prevent this shrinking.
Side effects and other risks of CBD
Overall, the available evidence suggests that CBD is well-tolerated. However, determining whether there are long-term risks of CBD use will require further studies.
So far, no reports of lethal CBD overdoses exist. Some researchers may be concerned about CBD abuse, but information on significant complications is limited.
Researchers do report that CBD may cause other adverse effects, including:
- alterations of cell viability, in studies conducted in cell cultures
- decreased fertilization capacity
- inhibition of drug metabolism in the liver
- decreased activity of P-glycoprotein and other drug transporters
If these effects on drug metabolism and transportation are confirmed, it would indicate that CBD interferes with other medications. Overall, more research is necessary.
Still, it is a good idea for anyone who wants to use CBD to speak with a healthcare provider first.
