In Louisiana there are in jail for using marijuana. We do have some judges who may not agree with mandatory penalties but they follow the law. Again if a user is in possession of 29 grams of marijuana, the penalty is 5 to 30 years and up to $50,000 fine. I know a woman who spent several months in jail because she gave a ride to someone who had Rx pills in her purse that were not in the Rx bottle. She did not know the rider had any Rx pills in her purse. But she was jailed. Sentenced for 6 mos. got out in 4.mos.
