Cannabis sativa may be used therapeutically to mitigate pregnancy-induced nausea and vomiting. This paper presents the results of a survey of 84 female users of medicinal C. sativa, recruited through two compassion societies in British Columbia, Canada. Of the 79 respondents who had experienced pregnancy, 51 (65%) reported using cannabis during their pregnancies. While 59 (77%) of the respondents who had been pregnant had experienced nausea and/or vomiting during pregnancy, 40 (68%) had used cannabis to treat the condition, and of these respondents, 37 (over 92%) rated C. sativa as ‘extremely effective’ or ‘effective’.
