Im 37 weeks and 4 days. how long will it take for my system to clear of thc?

1-4 months.: It usually clears out in a month but sometimes can stay for a longer period of up to 4 months or more. If you are a heavy smoker or are overweight, the THC may be in your system longer.

Yours or babies ?: If you are suspected of drug use they will usually test your urine. Light use might clear in a week, heavy in months. If you are on the CPS list & I investigate baby, I can find evidence of any exposure from the 2nd trimester on. It is best you be honest with your delivery team.
