Using Marijuana Before Pregnancy More Than Doubles The Risk Of Premature Birth, Says Study
Women who use marijuana before pregnancy more than double their risk of giving birth to a premature baby, says a study conducted by researchers at the University of Adelaide and published in the journal PLoS ONE.
According to previous research conducted by researchers at Tufts University, mothers who used marijuana as teenagers put their children at an increased risk for future drug use and abuse. As Research Assistant Professor John J. Byrnes, the lead author of the Tufts study, commented:
“[T]he results suggest that maternal drug use, even prior to pregnancy, can impact future offspring.”
The present study on maternal marijuana use from the University of Adelaide brings more bad news to women who used marijuana prior to conceiving.
According to the study, which looked at 3,234 healthy pregnant women without any previous children, factors such as a family history of low birth weight, diabetes before and during pregnancy, and hypertension all increase the risk for premature birth.
More surprisingly, however, is that regular marijuana use up to the time of conception is associated with a more than doubled increase risk of giving birth to a premature baby. As the researchers conclude:
“We have shown that marijuana is a strong environmental risk factor…in this population. We are unable to determine whether this association is due to a toxic effect of marijuana or is a marker of a suite of lifestyle factors that contribute to the risk. Pre-pregnancy marijuana use may be a more reliable marker since one can anticipate that women would be more likely to disclose it than persistent marijuana use during pregnancy.”
However, as the researchers point out, the reason for the increased risk of premature birth linked to marijuana use has yet to be determined. The marijuana may be directly to blame, or additional lifestyle factors associated with marijuana use may be the cause.
The results of this study are in contrast with a previous study that did not find a link between maternal marijuana use and premature birth.

If pot smoking months or years before pregnancy caused problems with children, there would have been an enormous spike in birth defencts or other problems following the society-wide increase in pot-smoking during the late 60's. There was none, no correlation, no relation.

I don't think this should even be a question….just don't take the risk…there is no reason to be smoking pot in the first place; and it definatly shouldn't be argued that it's medical use justifies women smoking illegally before having kids. Just don't use it.

Deceptive headline. No evidence to support that use of pot before birth has any effect. The study it self says this. Reading comprehension is fundamental.
Jul 23, 2012
As the researchers said, these results are in contrast to previous studies. It also sounds as if the researchers think other lifestyle factors and not just marijuana use account for the increase.

"Using Marijuana Before Pregnancy More Than Doubles The Risk Of Premature Birth, Says Study" That is the title of this article.." " More surprisingly, however, is that regular marijuana use up to the time of conception is associated with a more than doubled increase risk of giving birth to a premature baby."
That is your quote to your article…"It also sounds as if the researchers think other lifestyle factors and not just marijuana use account for the increase…. This whole article is so mixed up that even you as the writer can't even get the story straight..The title to this article is wrong and very deceptive.. I hate this kind of journalism.. All it does is piss off the educated and logical thinking readers…

Research doesn't make it legal…and it messed up my brother's life. Everyone is entitled their own opinion though.
Jul 23, 2012
How did it mess your brothers life? Did he get arrested? that alone is why the laws needs to be changed..This is about the rights of people who need this for their medical needs.. Research the laws and the injustice that has been done.. Alcohol is perfectly legal; I imagine more lives have been messed up with that substance.. It is ok for you to go get bombed out of your mind and may even die from alcohol poisoning..That is the truth right there.. logical thinking can set you free..

Education is the key to our survival… I do urge everyone to research the facts and the truths.. I do think marijuana should be legal for adult use as well as for medical use for anyone of any age..Yes, marijuana can be abused, but so can foods and any other substances we put in our bodies. A person can sit there and eat all day long and gain an enormous amount of weight. That right there can "mess up" someones life. Does that mean food has to be banned? No, that is illogical. I am a logical thinker. And I am tired of being spoon fed BS.. I call it like i see it.
