“Nausea and vomiting are common and distressing adverse events of chemotherapy.
This review focuses on the findings and quality of systematic reviews (SRs) of cannabinoids for chemotherapy-induced nausea and vomiting (CINV).
On the basis of findings of the sole SR judged as high methodological quality, cannabinoids seem to be more effective than placebo, equal to prochlorperazine for reducing CINV, and to be preferred by patients.
Cannabinoids represent a valuable option for treating CINV, despite the adverse events related to treatment, such as drowsiness and cognitive impairment.” https://www.ncbi.nlm.nih.gov/pubmed/29168289
