How long does weed stay in your system one week?

According to recent research, conducted by the university of manhattan, "weed" or "pot" as the young call it, is in your system for long periods of time. After doing a 25 year study on it, scientists found that when someone took it at the age of 20, it remained in their system, even after they were deceased. People that take "weed" will never pass a drug test, be allowed out or into a country, or have any children (you are infertile, so you can lose the condom)

I hope that this was informative.
