THC is able to stay in a person's system for a relatively long period of time because it is fat-soluble. Being fat-soluble allows it to be stored in fatty tissues of various organs. From here, THC is slowly released and metabolized. This metabolite of THC is then excreted and cleared from a person's system.

This site said it can stay in your system for a month or more after you do it.
