Beware, there are a lot of strange people in college.
You might find that your roomate has gone through your stuff and found your stash and reported you.
I repeat strange people.
Just trust me on this.

If you really can't leave it at home, but don't want to bring it right away, pack a box that is ready to take to your school at your convience. You get to play it as safe as it gets until you know your roomie, and your parents will never (hopefully) tear through your already packed and marked box.

just my few pennies anyway
