Researchers from King’s College London have investigated the impact of short-term use of two important psychoactive constituents in cannabis on healthy volunteers: delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).By analysing the results from 15 studies involving a total of 331 participants, the research showed that a single dose of THC could induce psychiatric symptoms in people with no history of psychotic or other major psychiatry disorders.
Four of the 15 studies examined the effects of CBD on psychiatric symptoms induced by THC in healthy volunteers. Analysis of these studies showed that CBD did not induce any of the three types of psychiatric symptoms. There was no consistent evidence across the four studies that CBD moderates the effects of THC in healthy volunteers.
