According to WHO, schizophrenia is a psychosis, a type of mental illness characterized by distortions in thinking, perception, emotions, language, sense of self and behaviour.
Schizophrenia is characterised by abnormal dopamine synthesis and release in the brain.
Senior author Romina Mizrahi, MD, PhD, of the Centre for Addiction and Mental Health, in Toronto says, “Regular cannabis use has a profound effect on cortical dopamine function, in particular in relation to the stress response, which is critical for young adults at risk for psychosis.”
This study, according to Science Daily, provides the first ever evidence of a “blunted response to stress-induced dopamine signaling in the brain's prefrontal cortex in individuals at high risk for psychosis who regularly used cannabis.”
Apart from Schizophrenia, Marijuana has many short-term effects on the brain such as,
· Mood change
· Impaired memory
· Temporary Hallucinations
· Altered senses and more
Not only mental disorders, cannabis also has ill effects on physical health like breathing problems and increased heart rate.
