Do I need a lawyer for a drug paraphernalia charge?

I was pulled over by an officer because the light that illuminates my license plate was out. While reaching for my insurance the officer saw a pipe I had in my glove box. He asked to see it so I handed it to him. The pipe had marijuana residue in it so the officer searched my car. They brought a drug dog out and everything. They did not find anything and I was let go with a citation for drug paraphernalia and a court date. I'm 18, in college and have no previous criminal record. I was wondering what my options are as far as legal representation and if I would be eligible for differed disposition.
