| For the new study, researchers in the Netherlands followed more than 7,000 pregnant women, 3 percent of whom acknowledged smoking marijuana at least during early pregnancy. They found that babies born to marijuana users tended to weigh less and have smaller heads than other infants. What's more, the study found, the longer a woman had used marijuana during pregnancy, the stronger the impact on birth size -- suggesting that the drug itself was to blame. |
