Study Participation, Expression of Interest

Thank you for your interest in participating in the PreCeeDo study. The aim of this study is to examine the feasibility and acceptability of conducting a large prospective cohort study and to explore the clinical utility of testing umbilical cord tissue to detect and quantify in-utero cannabis exposure.

Participation in this study includes completion of an initial online survey, monthly pregnancy follow-up surveys, umbilical cord sampling after delivery, and postnatal surveys every 2-3 months after your baby’s birth. In order to participate in this study, you need to provide consent. Please fill out the form below to express your interest in the study and let us know when you are available for a 20-30 minute phone call to review and electronically sign the consent form. You will be able to access a PDF copy of the consent form after entering your contact information.

You can participate in this study if you are currently 20 or more weeks pregnant, have a singleton pregnancy, you are 19 years of age or older, you hold a BC CareCard or Services Card, and plan on delivering at BC Women’s Hospital. Please note that you do not have to be using cannabis to be eligible to participate as we are including a control group of women who do not use cannabis.
