FACT CHECK – FALSE: Medicinal cannabis does NOT help treat depression, anxiety or ADHD, reveals review of 83 scientific studies

A post recently claimed that Cannabis does not aid in treating mental health conditions.

This article is nothing but another click-bait post.

Australian scientists reviewed 83 studies involving 3,000 people to come to their conclusion.

Firstly, this is a tiny sample from a huge pool of varied users.

There are over a million users in the UK alone. 3,000 is 0.30%.

A sample of 1% of any population or demographic would never be enough to come to a correlative conclusion.

Cannabis use, particularly strains with high THC content, increases your risk of developing a psychotic illness such as schizophrenia.

Then why do only 1/10 get addicted or develop a condition? Cannabis only leads to psychosis or mental illness IF you have an underlying condition.

There is no evidence to suggest there is a direct correlation between Cannabis and mental illness.

Cigarette smoking is responsible for more than 480,000 deaths per year in the United States, including more than 41,000 deaths resulting from secondhand smoke exposure. This is about one in five deaths annually, or 1,300 deaths every day. On average, smokers die 10 years earlier than nonsmokers

Unlike Tobacco which we know is to be harmful with no medical benefits, Cannabis has been proven to aid in reducing depression, anxiety

The results of the study showed that patients inhaling cannabis saw a significant reduction in their adverse feelings with depression symptom being reduced in 89.3% of sessions. However, the study also revealed that the symptoms of depression were exacerbated in a total 3.2% of sessions, and there was no change in 7.5% of sessions.


The facts are, studies can go both ways. There is plenty of evidence of sponsorship bias in clinical and medical research.

Bias in favour of industry is apparent in every one of the themes examined with the result that research funded by industry undermines confidence in medical knowledge.


So why should we trust a single study? We shouldn’t. We should be able to use a wide range of sources to inform. No one is saying it’s 100% safe.

Cannabis can be detrimental to users of developing brain, like any stimulant or depressant.


Don’t believe everything you read. There is always more behind the story. Make your own mind up.

I work on the basis of morality, my decisions are based on morality.

If a patient can refuse treatment, then they have the autonomy to chose which treatment they go for and that decision should only be between the patient and chosen registered clinician.
