Helping Schizophrenia with CBD Oil

Threating psychiatric disorders is never an easy task. The brain is a complicated organ, and science is still working to unlock its mysteries.

Doctors often describe schizophrenia as a type of psychosis. This means the person may not always be able to distinguish their own thoughts and ideas from reality.

Schizophrenia is a sever long-term mental health condition. It causes a range of different psychological symptoms.

Symptoms of Schizophrenia:

  • Hallucinations – Hearing or seeing things that don’t exist
  • Delusions – Un usual beliefs not based on reality
  • Muddles thoughts – based on hallucinations or delusions
  • Changes in behaviour

Some people think Schizophrenia causes a “split personality” or violent behaviour. This is not true!


Hallucinations are where someone sees, hears, smells, tastes or even feels things that don’t exist outside their mind. The most common hallucination is hearing voices. Some people describe the voices they hear as friendly and pleasant, but more often they're rude, critical, abusive or annoying. Research using brain-scanning equipment shows changes in the speech area in the brains of people with schizophrenia when they hear voices. These studies show the experience of hearing voices as a real one, as if the brain mistakes thoughts for real voices.


A delusion is a belief held with complete conviction, even though it’s based on a mistaken, strange or unrealistic view. It may affect the way the person behaves. Delusions can begin suddenly, or may develop over the weeks or months. Some people develop a delusional idea to explain a hallucination they're having. For example, if they have heard voices describing their actions, they may have a delusion that someone is monitoring their actions. Someone experiencing a paranoid delusion may believe they're being harassed or persecuted. They may believe they're being chased, followed, watched, plotted against or poisoned, often by a family member or friend.

Some people who experience delusions find different meanings in everyday events or occurrences. They may believe people on TV or in newspaper articles are communicating messages to them alone, or that there are hidden messages in the colours of cars passing on the street.

Changes in behaviour and thoughts

A person's behaviour may become more disorganised and unpredictable, and their appearance or dress may seem unusual to others. People with schizophrenia may behave inappropriately or become extremely agitated and shout or swear for no reason. Some people describe their thoughts as being controlled by someone else, that their thoughts aren't their own, or that thoughts have been planted in their mind by someone else. Another recognised feeling is that thoughts are disappearing, as though someone is removing them from their mind. Some people feel their body is being taken over and someone else is directing their movements and actions.

Treating Schizophrenia

Schizophrenia is usually treated with a combination of medication and therapy tailored to each individual. In most cases, this will be antipsychotic medicines and cognitive behavioural therapy (CBT). People with schizophrenia usually receive help from a community mental health team, which offers day to day support and treatment.

These specialist teams provide treatment and support, and are usually made up of psychiatrists, psychologists, mental health nurses, social workers and support workers.

There is a lack of effective treatment options for people with schizophrenia.


Can CBD help

A recent rat modelled study found that Cannabinol (CBD) derived from cannabis may help with cognitive impairment related to schizophrenia. In the study, rats were infected prenatally with polycytidilic acid. The acid helped replicate symptoms similar to those seen in psychiatric disorders like schizophrenia and produced a generation of mice with symptoms. Once born, the mice were treated using chronic CBD treatment and were tested on social interaction and cognitive function.

The symptomatic mice were given 10 mg of CBD for three weeks. Many factors were measured, including body weight, food and water intake. A battery of tests was conducted on the mice during and following their treatment with CBD. The tests were conducted as a means of looking at the effectiveness of CBD in helping counteract some of the cognitive symptoms of schizophrenia; they included T-maze tests, novel object recognition tests and social interaction tests.

The effects that CBD had on the mice could indicate a major breakthrough in the world of schizophrenia treatment. It appears to achieve something that no other medications have been able to do, including rebuilding cognitive potential and improving social interaction.


While the use of cannabis as a recreational drug has been linked to paranoia, anxiety, and psychosis, it is the psychoactive compound tetrahydrocannabinol (THC) that causes both the high and the side effects of cannabis. The other main cannabinoid found in cannabis, cannabidiol (CBD) does not cause a high and it is believed that it can counter the effects of THC, because of the way that it works to stimulate both CB1 and CB2 cannabinoid receptors in the body.


What is the correct Dosage of CBD Schizophrenia?

One of the reasons that many physicians are still hesitant to recommend the use of CBD oil for schizophrenia is that not enough research has been into the dosages that should be taken. It is known that different people react to CBD in slightly different ways. A person’s weight and height, for example, can affect how CBD reacts in the body. The severity of schizophrenia can also vary considerably between different people. Therefore, it’s advisable to begin taking CBD for schizophrenia at a very low dosage and then gradually increase it while monitoring the effects.

CBD oil can be purchased in different concentrations, so users need to be aware of the amount of CBD that will be in each “serving”. To help schizophrenia, a dosage of between 40mg and 1,280mg daily is usually suggested. It is recommended that you start off at the lower of the two levels and increase the dosage every few weeks until you feel an improvement in the symptoms. It must also be stressed that CBD oil must not be taken as an alternative to the medication prescribed by your doctor unless you have discussed this with your doctor beforehand.
