Cbd and birth control

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)

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.
