Kathryn Fuller was travelling in the war-torn country with Rice when they were allegedly sold tainted cocaine by a local cab driver last month (Feb12).
Fuller was left partially paralysed as a result of her reaction to the drugs and Rice was pronounced dead at a nearby hospital after he was found unresponsive inside the pair's Kampala hotel room.
Fuller appeared in Buganda Road Magistrate Court on Thursday (01Mar12) and she was charged with smoking and sniffing narcotic drugs, which is a violation of the National Drug Policy and Authority Act of 2000.
She was also hit with a $400 (GBP250) fine, according to local newspaper the Daily Monitor.
A cause of Rice's death has not yet been determined but ""major metabolites of cocaine"" were found in the 39 year old's blood stream.
The pair's driver, Moses Kalanzi, has since been taken into custody amid allegations he supplied the contraband to the pair. He has denied charges of manslaughter and supplying restricted drugs to the deceased. He is due back in court on 15 March (12).
