Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess how Cannabidiol (CBD) impacts the effectiveness of oral contraceptive (birth control) pills and if CBD changes the possible side effects of birth control pills when CBD and birth control pills are taken at the same time. This study explores the potential interaction between CBD and birth control pills by assessing serum levels of the contraceptive steroid hormones ethinyl estradiol and levonorgestrel in birth control pill users when they also use CBD.
