Unless you're a huge drug dealer, you're not gonna get even CLOSE to 20 years for possesion of marijuana. Any sensible ammount in possesion is just a misdemeanor... trust me, I should know.
Last.FM - Ow, give up the funk
Let the truth of love be lighted
Let the love of truth shine clear
Armed with sense and liberty
With the heart and mind united
In a single perfect sphere
