The Adverse Effects of Concurrent Tobacco and Marijuana Use
A new study by American scientists found that using tobacco and marijuana during pregnancy has significant adverse effects.

According to a report on May 9th from the Journal of Clinical Endocrinology and Metabolism, a new study conducted by American scientists has found that the simultaneous use of tobacco and marijuana during pregnancy can have significant adverse effects on both the mother and the baby, far exceeding the impacts of using each product separately. In particular, the increase in infant mortality rate is most pronounced, with the risk increasing fourfold.

 

This research was conducted by Adam Crosland and his colleagues at the Oregon Health and Science University. They analyzed data from hospital discharge and death records in California from 2012 to 2019, identifying all women carrying singleton pregnancies between 23-42 weeks of gestation for the study. During this period, they found that the prevalence of marijuana use among participants increased from 0.5% to 1.0%, smoking rates decreased from 2.1% to 1.5%, while the proportion of simultaneous users remained stable at 0.3-0.4%.

 

In an analysis of pregnancy outcomes in women, a research team has found that the frequency of hypertension significantly increases in pregnant women who use both tobacco and marijuana. At the same time, there is also an increase in the demand for emergency assistance and the frequency of premature births in these groups. They found that the birth outcomes of infants were more unfavorable. In the combined use group, the infant mortality rate was four times higher than the control group; the neonatal mortality rate and their hospitalization rate in the intensive care unit also increased; at the same time, the frequency of low birth weight in children also sharply increased.

 

Researchers have concluded in their report that using both cannabis and tobacco during pregnancy significantly increases the risks for both the mother and particularly the baby. They advocate for taking these risk factors into full consideration when consulting pregnant women and designing health programs for the prenatal period.
