A misdemeanor is a minor offense generally punishable by paying a fine, although more serious misdemeanors may carry a prison sentence. Examples of misdemeanors include possession of marijuana, disorderly conduct, and driving under the influence. A felony, on the other hand, is a more serious conviction punishable by imprisonment of one year or more. Felony convictions include such things as murder, embezzlement, sexual assault, and more serious drug-related charges. A conviction in either case can have significant implications, and it is important to be represented by a qualified legal professional.
