Health & Safety Code 11377 makes it illegal to possess certain drugs, including methamphetamine. It is a "wobbler," which means it can be charged as a misdemeanor (maximum punishment: 1 year in jail) or a felony (with a potential three-year state prison sentence).
If you or someone you know is charged with this crime you may be eligible for certain drug programs, such as Deferred Entry of Judgment (DEJ), or Prop 36. Both involve the completion of drug classes to earn a dismissal.
California Health and Safety Code Section 11377 (a) is:
