( CNN ) -- A federal appeals court in Argentina has ruled that a grandmother must stand trial for growing two marijuana plants in her backyard . Argentina allows personal consumption of marijuana , and a federal judge had issued a stay against prosecuting the unnamed woman , who swore she used the marijuana solely for herself , the government 's Judicial Information Center said last week . But the public prosecutor 's office appealed the ruling , and a federal appeals court overturned the previous decision because the woman lives with her two sons and a grandchild . She could not prove the marijuana was solely for personal consumption , the three-page appeals court ruling said . Argentina 's Supreme Court ruled in August it is unconstitutional to punish an adult for private use of marijuana -- as long as the use does n't harm anyone else . The unanimous ruling made Argentina the second Latin American country within a one-week span last year to allow personal use of a formerly illegal drug . Mexico also enacted a law in August that decriminalized possession of small quantities of most drugs , including marijuana , heroin , cocaine and LSD . Earlier last year , a Brazilian appeals court ruled possession of drugs for personal use is not illegal .
