A number of studies reported low birth weight and physical abnormalities among babies exposed to marijuana in utero. However, when other factors known to affect pregnancy outcomes were controlled for-for example, maternal age, socio-economic class, and alcohol and tobacco use-the association between marijuana use and adverse fetal effects disappeared. Numerous other studies have failed to find negative impacts from marijuana exposure. However, when negative outcomes are found, they tend to be widely publicized, regardless of the quality of the study.
Also used as evidence of marijuana-induced fetal harm are two longitudinal studies, in which the children of marijuana users were examined repeatedly. However, on closer examination, the effects of marijuana appear to be quite minimal, if existent at all. After finding a slight deficit in visual responsiveness among marijuana-exposed newborns, no differences were found at 6 months, 12 months, 18 months, or 24 months. At age 3, the only difference (after controlling for confounding variables) was that children of "moderate" smokers had superior psycho-motor skills. At age 4, children of "heavy" marijuana users (averaging 18.7 joints/week) had lower scores on one subscale of one standardized test of verbal development. At age 6, these same children scored lower on one computerized task-that measuring "vigilance." On dozens of others scales and subscales, no differences were ever found.
In another study, standardized IQ tests were administered to marijuana-exposed and unexposed 3 year-olds. Researchers found no differences in the overall scores. However, by dividing the sample by race, they found-among African- American children only-lower scores on one subscale for those exposed during the first trimester and lower scores on a different subscale for those exposed during the second trimester.
Although it is sensible to advise pregnant women to abstain from using most drugs-including marijuana-the weight of scientific evidence indicates that marijuana has few adverse consequences for the developing human fetus.
