Facts on marijuana use during pregnancy
posted 6th Oct '08
Studies of newborns, infants and children show no consistent physical, developmental, or cognitive deficits related to prenatal marijuana exposure. Marijuana has no reliable impact on birth size, length of gestation, neurological development, or the occurence of physical abnormalities. The administration of hundreds of tests to older children has revealed only minor differences between the offspring of users and nonusers, and some are positive rather than negative.
In animal studies, THC has been shown to produce spontaneous abortion, low birth weight, and physical deformities... but only with extremely large doses, only in some species of rodents, and only when the THC is given at specific times during the pregnancy. Studies with primates show little evidence of fetal harm from THC. In one study, researchers exposed chimpanzees to high doses of THCfor up to 152 days and found no change in the sexual behavior, fertility, or health of their offspring.
Dozens of studies have compared the newborn babies of women who used marijuana during pregnancy with the babies of women who did not. Mainly, they've looked for differences in birth weight, birth length, head circumference, chest circumference, gestational age, neurological development, and physical abnormalities. Most of these studies, including the largest study to date with a sample of over 12,000 women, have found NO differences between babies exposed prenataly and babies not exposed. Given the lartge number of studies and large number of measures, some differences are likely to occur by chance. Indeed, researchers have found differences in both directions. In some studies, the babies of marijuana users appear healthier and hardier. In others, researchers have found more adverse outcomes in the babies of marijuana users.
When adverse outcomes are found, they are inconsistent from one study to another, always relatively minor, and appear to have no impact on infant health or mortality. For example, in one recent study, researchers reported a statistically significant effect of marijuana on birth wieght. The marijuana exposed babies, on average, were less than two tenths of an inch shorter. Another study found a negative effect of marijuana on birth weight, but only in white women. In a 3rd study, marijuana had no effect on birth weight, but a small negative effect on gestational age. Overall, this research indicates no adverse effect of prenantal marijuana exposure on the physical health of newborns.

So please lose the "WEED IS BAD" mentality and take a look at the facts. I do not endorse the use of any other drug during pregnancy. But I challenge anyone, based on FACTS, to convince me that I am harming myself or my baby by smoking/eating weed. By the way, there have been 0 cases of lung cancer from smoking only marijuana, and those who smoke both marijuana and cigarettes are less likely to get lung cancer. There have been 0 reported deaths caused by marijuana.
