Violating the law is punishable by up to 60 days in jail upon conviction for a first offense.

Every state has DUID (driving under the influence of drugs) legislation on the books. These laws fall into three distinct categories: Effect-Based DUID Laws, Per Se DUID Laws, "Zero Tolerance" Per Se Laws.
