A new government funded study published in "Psychiatric Research" has found that heavy cannabis use can lead to better emotional memory and brain function in those who are schizophrenic.
The researchers performed a functional magnetic resonance imaging study of emotional memory in schizophrenia patients with cannabis abuse.
Researchers concluded that emotional memory and prefrontal lobe functioning is preserved in patients who are both schizophrenic and cannabis users, or dual-diagnosis patients.
The results are apparently consistent with previous findings where cannabis abuse is associated with fewer negative symptoms and higher cognitive functioning in schizophrenics.
The study was conducted by the Department of Psychiatry at the University of Montreal and funded in part by the Canadian Institute of Health Research
The Canadian study is especially interesting when compared to a study done by the University of Maryland School of Medicine, where teenagers who frequently smoked marijuana had a greater risk of developing schizophrenia.
Cannabis is especially harmful to those with a genetic predisposition for schizophrenia given that it can be triggered or drug-induced.
