A Riverside man serving a 32-year jail term for a brutal murder and beheading appeared in the Launceston Magistrates Court on Wednesday.
Jack Harrison Vincent Sadler, 29, appeared via video from Risdon Prison on a charge of possession of a controlled drug and a count of driving with a illicit drug in his blood.
Police prosecutor Trudi Lusted told Magistrate Sharon Cure that Tasmania Police would offer no evidence on the charges.
Ms Cure dismissed the charges.
Sadler was convicted in May of the murder of Jake Anderson-Brettner, 24, at Sadler's Riverside home on August 15, 2018.
He has appealed to the Court of Criminal Appeal claiming the jail term with a 20-year non-parole period is excessive.
The trial heard that Sadler's then partner Gemma Elizabeth Clark purchased L plates on the night they drove to the Sideling to dispose of Mr Anderson-Brettner's body parts.
