Currently drafting a manuscript that aims to:

• determine the level of exposure to tobacco and cannabis in pregnant women from six race/ethnicity groups (Black, Hispanic, Asian Indian, Native American, Vietnamese, and White) in the first three years following legalization of recreational marijuana use in 2018 in California

• identify demographic, socioeconomic, and neighborhood factors that identify subgroups with the highest tobacco and cannabis exposures within each race/ethnicity group

• assess whether prenatal exposure to tobacco is associated with exposure to cannabis in six race/ethnicity groups
