With Americans and people around the world becoming more open about marijuana, many studies are being done to determine the many medical uses for cannabis. Well it turns out there's a new condition that could benefit greatly from the drug: Schizophrenia.

A new study attempted to determine the impact cannabidiol (CBD) has on patients with schizophrenia. To do so, the researchers took two groups of patients with the condition and gave half of them CBD and the other half a placebo to use in addition to their normal medications. After six weeks, the scientists determined that the group taking CBD improved more than those that did not.

"After 6 weeks of treatment, compared with the placebo group, the CBD group had lower levels of positive psychotic symptoms and were more likely to have been rated as improved and as not severely unwell by the treating clinician," the study said. "Patients who received CBD also showed greater improvements that fell short of statistical significance in cognitive performance and in overall functioning. CBD was well tolerated, and rates of adverse events were similar between the CBD and placebo groups."

They concluded the study by saying, "These findings suggest that CBD has beneficial effects in patients with schizophrenia. As CBD’s effects do not appear to depend on dopamine receptor antagonism, this agent may represent a new class of treatment for the disorder."

Ironically, one of the "side effects" many people attribute to marijuana use is psychosis. Anti-cannabis advocates often use that as an argument against allowing young people access to the drug. And yet this study suggests that CBD may actually have anti-psychotic properties. 

Eventually, we're going to find out through all these studies that CBD can treat everything and it's ridiculous we haven't legalized its use yet.
