Misuse of marijuana (the drug is generally referred to as marijuana for the smoked or ingested substance and cannabis for plant parts or derivatives) is one of the most prevalent substance use disorders, particularly among young adults, and the demands for worldwide treatment have increased.
1 Marijuana (
Cannabis sativa L) belongs to the Cannabaceae family and is grown extensively globally.
2 During pregnancy, self-reported use of marijuana overall has ranged from 2% to 5% in several studies.
3 However, some studies have reported that when limited to populations of young women living in urban areas who are less advantaged socioeconomically, that number could be as high 15% to 28%.
3 Singh et al
4 reported that the prevalence of prenatal cannabis use was as high as 22.6% among their included studies from different countries. Authors report that testing for marijuana use at the time of delivery is associated with increased rates of use than is self-reported during prenatal care.
5 This finding, in part, may be secondary to the fact that many mothers using marijuana during pregnancy may not seek prenatal care at all.
6 Some authors
7 have suggested that the prevalence is thus likely underestimated, given that marijuana use is often underreported.
