A recent study has backed previous research that inferred that the risk of schizophrenia is high for people who use cannabis, especially among heavy users. 

According to the study published in the medical journal JAMA Psychiatry, weed is not as harmless as many people have come to believe. Carsten Hjorthøj, an associate professor at the Copenhagen Research Center for Mental Health and author of the study, maintained the necessity of publishing the study concerning laws governing marijuana use. He said, “I think it is highly important to use both our study and other studies to highlight and emphasize that cannabis use is not harmless.

“Since we see links with schizophrenia, poorer cognitive function, substance use disorders,” he continued. 

Millions of people around the world use marijuana for both recreational and medicinal purposes. The new study was based on data from Denmark’s national health registry. It covered people who were 16 years or older at some point from January 1, 1972, to December 31, 2016.

Cannabis use disorder is described as problematic use of the drug under one of these instances. 

  • developing tolerance to weed
  • using marijuana in large amounts or over a long period unknowingly 
  • being incapable of reducing cannabis use
  • spending a lot of time obtaining, using or recovering from the effects of cannabis
  • giving up important activities and obligations for cannabis
  • continued use of the drug despite negative consequences.

Schizophrenia is a terrible mental disorder in which people understand reality differently. This may result in some mixture of hallucinations, delusions, and extremely disordered thinking. Behaviours that impairs daily functioning are also symptoms associated with schizophrenia. People with schizophrenia require lifelong treatment.
