Since this plant is from the earth and completely organic, marijuana will stay in your system for well over 30 days.

You won't be happy about this answer. The THC in marijuana, which is what the lab will check for, can stay in your system for up to a month per usage. In other words, one joint equals one month you would have to wait to avoid having it show up in a drug screen.
