Impact of Cannabis Legalization on Umbilical Cord Tetrahydrocannabinol (THC) Levels.
Title: Impact of Cannabis Legalization on Umbilical Cord Tissue Tetrahydrocannabinol (THC) levels Objective: To assess the impact of cannabis legalization on both qualitative and quantitative umbilical cord tissue tetrahydrocannabinol (THC) rates and concentrations as a proxy for fetal exposure.
Study design: This is a retrospective, observational study of umbilical cord tissue THC levels in a single center, comparing THC exposure rates and concentration levels before and after cannabis legalization in the state of Illinois, Epoch 1 (October 1,2018-June 30, 2019, pre-legalization) and Epoch 2 (July 1, 2019-August 31, 2021, post-legalization).
Results: 811 umbilical cords were analyzed during epoch 1 and 2170 during epoch 2. A higher percent of umbilical cord tissue tested positive for THC in Epoch 2 compared to Epoch 1 (46.2% vs. 40.6%; p<0.01). Mean THC levels were 51% higher in umbilical cord tissue in Epoch 2 vs. Epoch 1 (6.2ng/gm vs 4.1 ng/gm; p<0.001).
Conclusions: Legalization of recreational cannabis was associated with more fetuses exposed to THC and in higher concentrations.
期刊介绍：
The American Journal of Perinatology is an international, peer-reviewed, and indexed journal publishing 14 issues a year dealing with original research and topical reviews. It is the definitive forum for specialists in obstetrics, neonatology, perinatology, and maternal/fetal medicine, with emphasis on bridging the different fields.
The focus is primarily on clinical and translational research, clinical and technical advances in diagnosis, monitoring, and treatment as well as evidence-based reviews. Topics of interest include epidemiology, diagnosis, prevention, and management of maternal, fetal, and neonatal diseases. Manuscripts on new technology, NICU set-ups, and nursing topics are published to provide a broad survey of important issues in this field.
All articles undergo rigorous peer review, with web-based submission, expedited turn-around, and availability of electronic publication.
The American Journal of Perinatology is accompanied by AJP Reports - an Open Access journal for case reports in neonatology and maternal/fetal medicine.
