According to several recent studies (on cannabidiol antipsychotic properties), Cannabidiol shows promise to alleviate certain psychotic symptoms and eventually may be considered as an alternative antipsychotic treatment.
Though not as potent as many antipsychotic medications currently on the market, CBD seems to have fewer side effects, is more cost effective (when compared to other medications with similar effects), and has been shown to be superior to most conventional antipsychotic medications.
A preliminary clinical trial at the University of California–Irvine has concluded that CBD seems to treat schizophrenia as effectively as current antipsychotic medications, with far fewer side effects and at a lesser cost. Daniele Piomelli, a professor of pharmacology at the university and co-author of the study said, “The results were amazing, not only was [CBD] as effective as standard antipsychotics, but it was also essentially free of the typical side effects seen with antipsychotic drugs.”
Common side effects of antipsychotic drugs include social withdrawal, lack of motivation, and anxiety, all of which frequently occur in schizophrenia as well. Therefore, since those drugs can themselves cause some of schizophrenia’s symptoms, it is still unclear whether CBD is better at treating them or whether it is simply causing fewer of these side effects in the first place. This is the focus of many current studies on CBD’s properties.
Perhaps most interesting of all is the fact that CBD seems to counteract the psychotropic effects of THC, which has been shown to have strong correlation with psychosis when used long-term. Using CBD alongside THC seems to drastically lower the potential of the latter to cause psychosis, a fact that has taken many scientific teams by surprise.
