More babies failing drug tests.
A clinical report published in the September 2018 Pediatrics cites statistics showing that more babies than ever are being exposed to marijuana. With marijuana now legal for medical or recreational use in more than half of U.S. states, marijuana use among pregnant women increased by 62% between 2002 and 2014 nationally. Meanwhile, marijuana has become more potent, with average concentrations of the psychoactive compound tetrahydrocannabinol (THC) more than quadrupling since the 1980s.
Christian Thurstone, director of the STEP Programme at Denver Health – one of Colorado’s largest youth substance-abuse treatment programmes – has conducted extensive research regarding marijuana and the developing brain. His research shows that children exposed to marijuana in utero have a 5-point decrease in IQ at age 6; a greater chance of depression, hyperactivity and impulsivity at age 10; and lower school achievement at age 14.
Approximately 70% of randomly selected medical marijuana centers in Colorado recommended marijuana as a treatment for morning sickness for pregnant women. Doctors caution that marijuana’s effects on a fetus could include low birth rate and developmental problems.
Colorado’s legalisation of recreational marijuana has led to an increase in the number of babies being born THC-positive. One Pueblo hospital is reporting nearly half the babies tested in one month had marijuana in their system.
According to a National Public Radio (US) report, a number of studies nationally suggest there’s been a sharp jump in pot use among pregnant women, especially among younger mothers… Researchers say psychoactive compounds in marijuana easily cross the placenta, exposing the fetus to perhaps 10 percent of the THC — tetrahydrocannabinol — that the mother receives, and higher concentrations if the mom uses pot repeatedly. Studies show marijuana increases the risk of stillbirth and adversely affects how a baby’s brain develops. Studies also show these kids may have behavioral problems at higher rates than other children by the age of 14, and are at greater risk for initiating marijuana use.
When mothers use marijuana during the first 12 years of their child’s life, their cannabis-using children are more likely to start at an earlier age than children of non-using mothers, according to a new study from the Harvard T.H. Chan School of Public Health published in the American Journal of Preventive Medicine in September. This study is the first to establish a relationship between maternal cannabis use during a child’s lifetime and earlier initiation in a nationally-representative, longitudinal cohort.
The National Survey on Drug Use and Health found that 28% of women living in low-income areas tested positive for marijuana use during pregnancy. Another study by the American College of Obstetricians and Gynecologists reported that young women from lower income levels have a 15–28% rate of marijuana use during pregnancy. Up to 60% of these young women continue marijuana use throughout pregnancy due to a decreased perception of risk and stigma.
