repeal medical purpose as a defense in prosecutions involving cannabis.

HB 1123 removes the ability to use a medical purpose as a legal defense in prosecutions related to cannabis possession or use in South Dakota. This change directly affects individuals who have been charged with cannabis-related offenses and previously might have argued they were using the substance for medical reasons. The bill eliminates the specific legal provision that allowed such a defense, meaning medical necessity will no longer be considered a valid justification in court. As a result, prosecutors will no longer need to prove that a defendant's cannabis use was not for medical purposes, and defendants cannot raise medical need as a shield against charges.
