Summary
This summary is machine-generated.Higher frequency of cannabis use before pregnancy significantly increases the risk of using cannabis during pregnancy. This highlights the need for early interventions and education for women of reproductive age.
Area Of Science
- Reproductive Health
- Public Health
- Substance Use Research
Background
- Prenatal cannabis use is rising and linked to adverse outcomes for mothers and infants.
- Identifying preconception risk factors is crucial for early intervention strategies.
- Universal screening in healthcare systems aids in identifying cannabis use patterns.
Purpose Of The Study
- To investigate the association between the frequency of cannabis use before pregnancy and its use during early pregnancy.
- To determine if preconception cannabis use patterns predict prenatal cannabis use.
Main Methods
- An observational study analyzed data from Kaiser Permanente Northern California (KPNC) from 2011-2022.
- Included pregnant individuals reporting any cannabis use in the year preceding pregnancy.
- Modified Poisson models assessed the link between preconception and prenatal cannabis use, adjusting for covariates.
Main Results
- Nearly half (45.1%) of the 40,806 pregnancies involved prenatal cannabis use.
- Daily (aPR=2.66) and weekly (aPR=1.99) preconception cannabis use were significantly associated with increased prenatal use.
- Findings were consistent whether prenatal use was determined by self-report or toxicology.
Conclusions
- Increased frequency of preconception cannabis use is a strong predictor of prenatal cannabis use.
- Emphasizes the necessity of early prevention, including screening and education, for women of reproductive age.
- Early linkage to intervention services is vital for reducing cannabis use during pregnancy.

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
