In addition to the reported effects of relaxation and pain reduction, many users of medicinal cannabis also use the substance as a means to relieve anxiety and certain sleep disorders such as insomnia. According to the National Cancer Institute, studies testing the effectiveness of cannabis showed that test subjects who inhaled marijuana had "improved mood, improved sense of well-being and less anxiety." Additionally, patients who ingested a cannabis plant extract spray (administered under the tongue) reported more restful sleep [source: National Cancer Institute].
