Can Genetic Chromosomal Testing Show Marijuana Traces?
My daughter is about to turn 14 months at the end of this month, she has to go for genetic testing in about a week. I have suffered with postpartum depression/anxiety and am a single mom... I work full time, and am a great mom, but just have been struggling with getting stressed out a lot. I will admit to smoking marijuana one time in the past few weeks to try to relieve stress but now I am extremely scared that when we go for the genetic screening that they may somehow see that I smoked and try to label me a bad mother. Can genetic chromosomal testing show anything like that?

not a bit.
Some studies show some chromosomal changes in the person doing the smoking. The exposure of the offspring is much less for smoking a lot during pregnancy, the chromosomal changes are smaller in theory, but there isn't a DNA test to detect drug use for detection even in heavy users. This isn't a test that is used in anything other than very preliminary research findings in heavy users. It wouldn't be specific for drugs of abuse in any case. There's no DNA drug test.
Furthermore, second hand marijuana exposure of even very very heavy use in a very small area doesn't show up on urine testing. The offspring's exposure is not enough to do anything from second hand exposure from one use. The DNA test wouldn't show it. There's no DNA standardized test for it even if the kid was doing blunts daily.

Hi there, to the best of my knowledge, a genetic test for chromosomal abnormalities would not show any exposure to marijuana. The test that would show that is typically called a urine toxicity screen or urine drug screen, and would not be done typically with a genetic screen. Furthermore, unless your daughter also was actively exposed to marijuana and using it, which I think is unlikely given her age, a drug screen done on your daughter would likely be negative. I do not think that you have much cause for worry if the only test being done is a genetic test. Best of luck to you and hope my answer was helpful.
