Drug Crimes, Substance Abuse possession of less than 1 oz

[emoney]

i was recently cited for possession of less than an ounce of marijuana. the officer told me i would not have to go to court, but simply pay a fine. when i got the summons i was told that i would have to appear. i had the same charge 7 years ago. what will the penalty be for a second offense, and how long does this stay on my dmv record as well?
