People who use recreational cannabis experience a number of responses to the THC content. THC is a psychoactive compound that produces the high associated with cannabis use, but it can cause negative side effects that include anxiety, paranoia and even hallucinations. Since CBD oil comes from the same plant that THC comes from, it is not surprising that people wonder if CBD oil can cause hallucinations, but in reality, there is nothing to be concerned about. In fact, CBD may even block the anxiety, paranoia and hallucinations associated with THC, due to its facilitation of the endocannabinoid system of the activation of 5-HT1A receptors.
Hallucinations are not a common side effect of THC consumption. They are more commonly associated with psychedelic drugs like LSD, mescaline and 2C-B, which act as antagonists of the neural receptor 5-HT2A. Their interaction with this receptor is responsible for the hallucinations that people experience, though not all 5-HT2A agonists have this effect. Other substances that cause hallucinations include tryptamines like DMT and psilocybin, which are serotonin analogues that can be found in certain mushrooms or plants. The means by which they produce hallucinations is still not fully understood, but they are known to interact with different 5-HT receptors in various ways.
With its various interactions with the receptors in the brain, it is not possible to say that CBD will never produce hallucinations, but recorded cases of this are few and far between. Far more prominent are the reports of CBD having beneficial effects on many aspects of human health without any of the psychedelic experiences associated with various recreational drugs including marijuana. There is even evidence that CBD may help dampen the abnormal brain activity that can cause the hallucinations and delusions linked with psychosis, paving the way for it to be recommended to help with these kinds of problems for patients in the future.
More to learn about CBD
There is still much to be done in terms of researching the ways in which CBD interacts with the brain and the effects it may have on our neurology and physiology. But the signs to date are encouraging, and CBD in itself bears no similarity to the psychoactive and psychedelic compounds known to cause visual and auditory hallucinations in people. If you are considering taking CBD oil as a supplement, it is recommended that you consult with your doctor first in case you are taking any medications known to interact with the compound. And it will take a process of trial and error to see what dosage of CBD works best for you, so be prepared to experiment a little.
