This study  examined the anti-emetic (anti-nausea) properties of the cannabinoid, Cannabidiol (CBD) which, as opposed to THC, has no psychoactive properties. The authors state that the results of this study are the first to demonstrate that the non-psychoactive component of marijuana [cannabis], cannabidiol [CBD], and its synthetic analog, cannabidiol dimethylheptyl [CBD-DMH], interfere with nausea and with condition nausea in rats.
