How Long Does Marijuana Remain In The System After Stopping It During Pregnancy?

default
Posted on Fri, 16 Oct 2015
Question: I'm 31 weeks pregnant and have been smoking higher potency marijuana about 2-3 times a day for the duration of my pregnancy, with a few weeks off and on of no use due to extreme nausea and hyperemesis gravidarum. It's literally the only way I've been able to keep food down. I stopped about three days ago, maybe four, but I'm concerned about how long it will take to leave my system before the baby is born. Pre-pregnancy I weighed about 113lbs with a BMI of 18.5. The only weight I've gained this pregnancy is strictly baby weight and I keep active daily. I've stopped cross training but I still walk anywhere from 6-8 hours a day and stay hydrated due to my job, and take my prenatals. I know that the time it takes to leave your system is conditional on the person but I'm wondering if I have a chance of testing positive if I go to full term (November 24).

Brief Answer:
Urine test will detect up to 45 days.

Detailed Answer:
Hello,

Welcome to Healthcare Magic.

I had gone through your question and understand your concerns.

No one can say how long you will test positive for marijuana but if you are a regular daily marijuana user the urine test will detect up to 45 days after stopping marijuana ( however most frequent users should pass a urine after 10 days but there is no guarantee) which means that you have a chance of testing positive.

There are several factors that can influence how long THC will be present in your urine like: body fat, weight or frequency of use. Higher percentage of body fat can take longer to detox.

Please note that smoking marijuana during pregnancy may affect your baby's growth and nervous system. Children who were exposed to marijuana may have problems focusing their attention and with short-term memory.

Hope I have answered your query. If you have any further questions I will be happy to help.
