Modes of Cannabis Administration and Polysubstance Use among Women Before and During Pregnancy

Despite increasing rates of prenatal cannabis use, little is known about how women administer cannabis before and during pregnancy; various modes may be associated with different THC levels and exposures to other substances such as tobacco. This study expands on our collaboration with the Kaiser Permanente Early Start program to examine patterns and trends in modes of cannabis administration; how modes relate to socio-demographics, clinical characteristics, and polysubstance use; and how pre-pregnancy modes relate to risk of prenatal cannabis use.
