If you are a woman and want to become pregnant how long does it take for marijuana to leave your body?

THC is absorbed in the body fatty tissues the amount of time it takes to have it out of your system depends on weight and how often and how much you smoke. It can take a month or longer to clear your system of it if you are a regular smoker.

Doctors advise pregnant women not to use any drugs because

they might harm the growing fetus. Although one animal study has

linked marijuana use to loss of the fetus very early in pregnancy,

two studies in humans found no association between marijuana

use and early pregnancy loss. More research is necessary to fully

understand the effects of marijuana use on pregnancy outcomes.

Some scientific studies have found that babies born to

women who used marijuana during their pregnancy display

altered responses to visual stimulation, increased tremors, and

a high-pitched cry, which may indicate problems with nervous

system development. During preschool and early school years,

marijuana-exposed children have been reported to have more

behavioral problems and difficulties with sustained attention

and memory than nonexposed children.

Researchers are not certain whether any effects of maternal

marijuana use during pregnancy persist as the child grows up;

however, because some parts of the brain continue to develop

into adolescence, it is also possible that certain kinds of problems will become evident as the child matures.
