Hole in my life

I saw Jack change when he first started smoking marajuana.  Before he started smoking he was a normal person that was able to stay out of trouble if he could and was just trying to make it through highschool to become a writer.  But after he started smoking he started getting into trouble making friends with the wrong people and not caring as much about his education, being a writer was still important to him but not as much as it was before.
