Proposition 64 legalized, among other things, the possession and purchase of up to an ounce of marijuana and allowed individuals to grow up to six plants for personal use. The measure also allowed people convicted of marijuana possession to petition the courts to have those convictions expunged as long as the person does not pose a risk to public safety. People also can petition to have some crimes reduced from a felony to a misdemeanor, including possession of more than an ounce of marijuana by a person who is 18 or older.
