Consuming cannabis while pregnant can have serious social repercussions. In some states, you may even have your child taken away. But, are these harsh concerns about prenatal cannabis use really accurate? Recent research suggests that the herb may be less harmful than we make it out to be. A  study says that smoking cannabis while pregnant is OK, as long as it’s in moderation.
Maternal marijuana use isn’t a risk factor
A team lead by Dr. Shayna Conner set out to determine whether or not prenatal cannabis use is associated with negative health consequences.
They performed a systematic review and meta-analysis of observational studies that compared rates of cannabis consumption to birth outcomes.
It is unethical to perform potentially harmful health experiments on pregnant women, so the majority of research on cannabis and pregnancy are observational and cell line studies.
After examining all of the data, the team found two primary outcomes popped up consistently: low birth weight and preterm delivery. Those who oppose cannabis use often use these two potential impacts as an argument against the herb. However, this new study found something interesting.
After sorting out tobacco use and other confounding factors, the researchers found no statistical correlation between cannabis use and any negative birth outcome. This lead them to conclude,
Maternal marijuana use during pregnancy is not an independent risk factor for adverse neonatal outcomes after adjusting for confounding factors. Thus, the association between maternal marijuana use and adverse outcomes appears attributable to concomitant tobacco use and other confounding factors.
