How long marijuana stays in placenta how many days? i am 26 weeks i don't want critisim i jus want to know how long it stays in placenta please only!

It depends...: This depends on how much you have used. The half-life of thc is 2-12 days; the more often you smoke the more accumulates & the longer it takes to eliminate. If the half life is 7 days (about average) that means 6 weeks after stopping 1/64 of it will still be there; if the half life is 10 days 1/16 will remain. See http://www.Mothering.Com/community/a/use-of-marijuana-during-pregnancy re: safety.

Just the facts: The: Level of thc in the placenta depends on the dosage & regularity of your use & how rapidly you metabolize the drug. "washout" doesn't work. If your baby's length, weight &/or head circumference are small for gestational age, it alerts you & the doctors of the need for early intervention for your baby's optimal development. Later-onset adhd, +/-learning & behavior problems can occur without sga.

Not where I look: If you end up on the Child Services watch list, we check your pee & babies first pee after delivery and also their 1st poop. The urine is less sensitive. The poop will retain evidence of any exposure to any drug in the preceding months. If you & your associates don't draw any suspicion they won't look, but accept that if you are using & they look, they will find it.
