Cannabidiol and Oral Contraceptive Pills Study

WHRU - Cannabidiol and Oral Contraceptive Pills Study

This study is investigating the effect of cannabidiol (CBD) on oral contraceptive pills when taken together. We believe that CBD may either change how effective birth control pills are at preventing pregnancy, or may change the side effects birth control pill users experience. As part of this study, you will receive CBD and oral contraception, but you do not have to be sexually active to participate. Participation will last up to 4 months and include 9 visits to our clinic at OHSU.


  • You are a woman between the ages of 18 and 39

  • You are in good general heath

  • You have regular menstrual cycles

  • You are not currently using hormonal contraception

  • You are not at risk for pregnancy (you are not sexually active, use a barrier method of birth control, have a copper IUD, have a partner with a vasectomy, have had a tubal ligation yourself, or are in a same sex relationship)

  • You are not currently using or have recently used THC and/or CBD products

  • You have a BMI of 29 or less


Qualified participants will receive all study related materials and exams at no charge and will be compensated up to $560 for their time and travel. The exact amount will depend on the number of visits and study requirements completed.
