Nausea is something every human deals with – it may be on a regular basis or just once or twice. The overall factor of nausea might make you think that CBD or THC would make it worse. The truth is CBD and THC has been used for hundreds of years to tone down the effects of nausea and help relieve anxiety connected to the nausea. Below is a scientific report on the benefits of CBD/THC when it pertains to nausea.
The anti-nausea/anti-emetic effects of CBD may be mediated by indirect activation of somatodendritic 5-HT1A receptors in the dorsal raphe nucleus; activation of these autoreceptors reduces the release of 5-HT in terminal forebrain regions. Preclinical research indicates that cannabinioids, including CBD, may be effective clinically for treating both nausea and vomiting produced by chemotherapy or other therapeutic treatments.
The cannabis plant has been used for several centuries for a number of therapeutic applications (Mechoulam, 2005), including the attenuation of nausea and vomiting. Ineffective treatment of chemotherapy-induced nausea and vomiting prompted oncologists to investigate the anti-emetic properties of cannabinoids in the late 1970s and early 1980s, before the discovery of the 5-HT3 antagonists. The first cannabinoid agonist, nabilone (Cesamet), which is a synthetic analogue of Δ9-THC was specifically licensed for the suppression of nausea and vomiting produced by chemotherapy. Furthermore, synthetic Δ9-THC, dronabinol, entered the clinic as Marinol in 1985 as an anti-emetic and in 1992 as an appetite stimulant (Pertwee, 2009). In these early studies, several clinical trials compared the effectiveness of Δ9-THC with placebo or other anti-emetic drugs. Comparisons of oral Δ9-THC with existing anti-emetic agents generally indicated that Δ9-THC was at least as effective as the dopamine antagonists, such as prochlorperazine (Carey et al., 1983; Ungerleider et al., 1984; Crawford and Buckman, 1986; Cunningham et al., 1988; Tramer et al., 2001; Layeeque et al., 2006).
