Cannabis abuse in young men linked to schizophrenia: study

A new study based on data from nearly 6 million people in Denmark ages 16 to 49 found that young men who regularly smoke marijuana may have an increased risk of developing schizophrenia. The study concluded that 15% of schizophrenia cases in males may be preventable if cannabis use disorder (CUD) was avoided. THC levels in cannabis have rapidly increased in recent decades, with potency in commonly used oils and edibles reaching upwards of 95%.
