Marijuana: Effects on the Mother

Prolonged use may lead to apathy, lack of energy, lack of desire to work or be productive, diminished concentration, poor personal hygiene, preoccupation with marijuana – the amotivational syndrome

Effects on the fetus

Marijuana can easily cross into the placenta, and causes increased levels of carbon monoxide in the mother’s blood, reducing the level of oxygen to the fetus.

With more states legalizing the sale of Marijuana, there are more users. Those that smoke or exposure to the smoke from their significant others who smoke, Need to be aware of the effect on the unborn fetus.

Issues

One issue with Marijuana use, is that often it has other street drugs combined with the plant itself. Or additional THC is added to compound the effects. These two, and other contaminants can create the issues that will be discussed regarding the development of the fetus, and the later development of the fetus through early childhood.

There have been few definitive studies conducted on humans as to the effects of Marijuana on the fetus. “A new study in animals suggests that children who are exposed to marijuana in the womb may suffer from a variety of long-term problems even if they aren’t born with obvious birth defects.”

One of the components of Marijuana, that the researchers call WIN, has shown an effect in studies conducted on lab rats. Although, not causing birth defects, Marijuana does cause memory loss and inability to learn. “Researchers say they also found that WIN interfered with the release of a brain transmitter called glutamate, a key chemical associated with learning and memory processing.”

An Italian research team found that marijuana caused a disruption from “chemical and electrical processes in the brain during gestation (Bhattacharya)” in lab rats. The effects the study indicates, can be confounded by smoking, wealth, and urban living.

Even second-hand Marijuana smoke can affect the unborn fetus. It can cause your baby to be born premature, and have a lower birth weight, both are risks for the baby. Studies are few and far between, due to the risks involved on the fetus. “In the very few studies available, there appears to be an increase in the incidence of premature labor and low birthweight. In cases in which pot had been tainted with a stimulant (cocaine, for example), there was an increased risk for dangerously fast labors (less than three hours) and for placental abruption (separation of the placenta from the uterine wall)” states Dr. David Barrera.

Observation has shown that “…babies born to women who abused marijuana during their pregnancies display altered responses to visual stimuli, increased tremulousness (trembling or shaking), and a high-pitched cry — any of which may indicate neurological problems in development”. Later in the child’s development these children have a lack of problem-solving skills, and poor memory.

Based on a study conducted by University of Utah School of Medicine, Salt Lake City, and colleagues in the Eunice K. Shriver National Institute of Child Health and Human Development, babies born to smokers of Marijuana are two times more likely to have stillborn babies.
