    This study found that regular marijuana use during pregnancy did not significantly change levels of key maternal hormones, including human chorionic gonadotropin and progesterone. These findings suggest cannabis consumption may not impact these specific pregnancy markers.

    Area of Science:

    • Obstetrics and Gynecology
    • Pharmacology
    • Reproductive Endocrinology

    Background:

    • Maternal serum hormone levels are crucial indicators of pregnancy health.
    • The impact of marijuana use, specifically delta 9-tetrahydrocannabinol (THC), on these markers during pregnancy requires further investigation.
    • Previous research on cannabis and pregnancy outcomes has yielded varied results.

    Purpose of the Study:

    • To investigate the effect of regular marijuana use throughout pregnancy on maternal serum concentrations of specific protein and steroid hormones.
    • To compare hormone levels in pregnant individuals who regularly use marijuana with those who do not.

    Main Methods:

    • Maternal serum samples were collected from 13 pregnant marijuana users and 13 matched non-using controls.

  • Hormone levels measured included human chorionic gonadotropin, pregnancy-specific beta-l-glycoprotein, placental lactogen, progesterone, 17-hydroxyprogesterone, estradiol, and estriol.
  • Cannabinoid use was confirmed by serum delta 9-tetrahydrocannabinol (THC) concentration measurements using radioimmunoassay (RIA).

    • Main Results:

    • Maternal serum concentrations of all measured protein and steroid hormones were within normal ranges for gestational age in both marijuana-using and control groups.
    • No significant differences were observed between the groups for any of the assessed hormones.
    • Linear regression analysis showed no significant association between THC use and placental hormone concentrations as a function of gestational age.

    Conclusions:

    • Regular marijuana use during pregnancy does not appear to significantly alter circulating maternal concentrations of major trophoblastic protein hormones or fetoplacental steroid hormones.
    • These findings suggest that, based on the markers studied, marijuana consumption may not have a substantial impact on these specific endocrine parameters during gestation.
    • Further research is warranted to explore potential long-term effects or impacts on other pregnancy-related biochemical markers.
