The answer
Unfortunately, TeenHealthFX cannot diagnose or treat over the internet. It is difficult to determine a definite answer as the amount of time marijuana stays in a persons's system varies. [Healthline explains that marijuana can stay in a person's system anywhere from 1-30 days and even up to 90 days for heavy users. We encourage you to continue to avoid marijuana use to ensure passing the pre employment test as well as for optimal health.
