“…This research has focused primarily on a handful of the multitude of medical conditions and symptoms for which the benefits of cannabis have been proclaimed anecdotally, including muscle spasm and chronic pain (Borgelt, Franson, Nussbaum, & Wang, 2013; Harrison, Heritier, Childs, Bostwick, & Dziadzko, 2015), nausea and vomiting (Smith, Azariah, Lavender, Stoner, & Bettiol, 2015), epilepsy (Friedman & Devinsky, 2015), appetite stimulation (Gorter, 1999), cancer (Pacher, 2013), and several psychiatric disorders (e.g., post-traumatic stress disorder, anxiety, depression; Betthauser, Pilz, & Vollmer, 2015; Zlebnik & Cheer, 2016). To date, the quality of evidence supportive of cannabinoid treatment for spasticity and chronic pain has been moderate, whereas only low-quality evidence was available to support its use for nausea and vomiting and for weight gain in patients with HIV/AIDS or cancer (for a review, see Whiting et al, 2015).…”
