Link Between Weed and Schizophrenia

"Cannabis is one of the most widely used substances worldwide,

with an estimated 228 million users aged 15 to 64. Research shows that the risk of developing schizophrenia increases significantly with cannabis use, particularly when use begins at an early age. 

Around 10% of cannabis users are expected to develop cannabis use disorder at some point in their lives. 

Notably, nearly one-third of people with schizophrenia also meet the criteria for cannabis use disorder, and as many as 42% of individuals with schizophrenia are affected by it.
Schizophrenia is defined by the presence of different types of symptoms which include delusions, hallucinations, or disorganized speech. Disorganized speech refers to a pattern of speaking that is incoherent, illogical, or difficult to follow."
