View all CBD for Schizophrenia

While THC results in psychoactive effects, CBD produces relaxation and pain relief. Hemp-derived oil is available in different medical counters for dozens of neurological issues. Currently, it is used to treat schizophrenia and its related symptoms. To know the connection between schizophrenia and marijuana, read on.

What is schizophrenia?

Schizophrenia is a serious mental illness that does not let people interpret reality. The disorder is associated with various symptoms including, delusions, intense disordered thinking, hallucinations, and more. Sometimes, patients become unable to perform daily functions or lead a routine lifestyle. Unfortunately, people suffering from this disease require lifelong treatment. Some symptoms can be controlled if treated early. Or, this can lead to serious complications and long-term suffering.

What’re the symptoms?

Many don’t know that this mental disorder comes with an array of problems, including behavior, cognitive, and dealing with emotions. Though signs and symptoms vary from one individual to another, some are quite common. These are:

  • Delusions - Patients suffering from schizophrenia tend to rely on false facts, which have no connection to reality. For instance, they may think that they will be harassed or harmed or they have extraordinary talents, or there’s a disaster going to occur soon. Delusions are common and reported in the maximum of the cases.
  • Hallucinations - Again, these are false beliefs, which involves hearing or seeing things far from reality. A schizophrenic patient cannot differentiate between a false image and reality. In hallucinations, hearing voices is the most common one.
  • Confused thinking and speech - Jumbled thinking comes from disorganized speech. Most of the time, communication is affected, and patients may fail to answer properly to many questions. Sometimes, patients combine lots of words and make a word salad that can’t be understood.
  • Abnormal motor behavior - This can range from sudden agitation to childlike stupidity. They can’t focus on a goal, and hence can’t perform any task. Abnormal motor functions include doing bizarre postures, not listening to instructions, lack of response, unnecessary movements, and more.
  • Negative indicators - Here, sufferers can’t function normally. For instance, a schizophrenic patient may neglect his/her personal hygiene. He or she may not show any kind of emotions, may not change facial expression, or make eye contact. Additionally, he or she may lose interest in communicating with people and doing regular chores.

With time, symptoms become severe and worsen. Even if there’s a stage of remission, some symptoms always stay. In men, you can encounter the signs in between early to mid-20s, whereas, in women, symptoms are visible in the late 20s.

Can children be affected?

The symptoms in teenagers are the same in adults, but they are difficult to diagnose. Early signs of schizophrenia in teens include:

  • Withdrawal symptoms;
  • No interest in talking to friends and family;
  • Lack of sleep;
  • Bad performance in school;
  • Depressed or irritated mood;
  • Lack of motivation;
  • Delusions and visual hallucinations.

What is CBD and how it works?

CBD is cannabidiol, derived from hemp plants. It can be sourced from marijuana plants as well as industrially grown hemp plants, but it is safe to consume the latter for recreational and medical purposes. Cannabidiol has been investigated to have antidepressant and neuroactive properties, which trigger the cannabinoid receptors of our body. It acts on releasing the serotonin from the brain as that plays a major role in fluctuating mood and developing depression.

CBD’s impact on these mood stabilizer receptors increases the level of serotonin and stimulates the brain to act accordingly. Smoking marijuana for schizophrenia has reduced the risk of psychosis in individuals. Studies revealed that patients have shown positive improvements in their cognitive ability, behavioral pattern, and speech on consuming CBD oil. There has been a noticeable change in other psychotic signs as well.

CBD and schizophrenia - The connection

Antipsychotic drugs work on the brain by releasing certain neurotransmitters, such as serotonin, noradrenaline, dopamine, and acetylcholine. As per studies, the release of excess dopamine leads to psychotic symptoms. However, antipsychotic medications get attached to dopamine reactors, minimizing their production.

A current study investigated cannabis effects on individuals who are vulnerable to getting psychosis. It is stated that people have shown increased brain activity after receiving CBD. This concluded that CBD for schizophrenia could normalize adjustment to brain areas partially, which is linked to psychosis development. Our reviews will further give you an insight into this.

Is cannabis a new treatment?

The effects of CBD oil for schizophrenia show similar results on patients consuming antipsychotic drugs. Improvements are found in cognitive and behavioral ability. Most of them have stabilized mood, appear happy and relaxed, reduced irritation, and improved physical functioning.

However, the effects are limited to certain symptoms and not all can be controlled. Moreover, marijuana schizophrenia treatment was induced on patients who were already on antipsychotic medications. Further research will be done on CBD’s standalone effect on psychosis and other related symptoms.

Can schizophrenia lead to suicidal thoughts and behavior?

Schizophrenia sufferers tend to have suicidal thoughts and actions. If you’ve encountered a schizophrenic patient who is vulnerable to self-harm or attempting suicide, make sure that someone stays with him/her always. Keep some local emergency numbers handy in the case of any mishap.

CBD and Schizophrenia Disorder.

Can CBD ease suicidal thoughts and depression?

Cannabis treatment for schizophrenia can ease suicidal thoughts and depressions according to research. Suicidal act evolves from traumatic experience or encounters. Hallucinations and delusions can lead to dangerous thoughts in the mind, leading to killing oneself.

Cannabis contains antipsychotic properties, which calms the nerves, significantly reducing depressing ideas. When CBD oil is consumed daily, patients show greater brain activity and lively mood, eradicating desperate reactions. Go through our reviews as more light has been shed on this.

Types of CBD you can use for schizophrenia

If you’ve got a schizophrenic patient in your house, purchase weed products with no presence of THC. CBD terms can be confusing and you may get jumbled on seeing the label. Here’s what you should look for before buying a CBD product:

  • Full-spectrum - This category of cannabis oil comes from the whole hemp plant, containing cannabinoids and traces of THC (not more than 0.3%). Though THC is negligible, it shouldn’t be given to a schizophrenic patient.
  • Broad-spectrum - This category of CBD doesn’t have THC and can be given to patients suffering from psychosis.
  • Pure CBD - This means you get 100% of marijuana extracts, but sometimes, they are sold in medical outlets with THC concentration. It’s better to skip this one.
  • Hempseed oil - You will find no traces of CBD in hempseed oil as these are sourced from hemp seed. To get away from legal troubles, many sellers sell CBD under the guise of hempseed oil.

How much to take?

If marijuana is taken to improve mental health, do consult a medical practitioner. Always go for a high-quality version of cannabis for schizophrenia treatment and stick to the prescribed dosage. The amount varies from one patient to another depending on how worsening the stage is. Patients may be suggested to begin 15mg of CBD oil once or twice a day. This CBD dosage for schizophrenia may increase up to 600 or 1000mg daily.

How safe is CBD?

Cannabis can cause side effects to some people like dizziness, irritability, nausea, dry mouth, diarrhea, and more. On consuming daily, you can severely affect your liver. Take a look at our top 10 product list and purchase safe CBD oil for medicinal purposes.

Does it interact with other drugs?

CBD oil and schizophrenia can co-exist well only if it doesn’t mingle with other medicines. According to a study, there are almost 60 drugs that interact with weeds. Therefore, one has to be extra cautious if they take medicines for heart ailments, blood thinners, and other drugs that adversely affect your immune system. Talk to a doctor before switching to CBD adjunctive treatment for schizophrenia.


CBD plays a significant role in schizophrenic patients. When used in the right amount, it triggers the cells in the brain and alters how the receptors respond. Cannabis comprises a host of curative and healing properties, which helps neurological disorders. However, schizophrenic patients shouldn’t take weed products containing THC or even mild traces.
