Judge Barbara Morris said the offence was "unsophisticated [and] easily detectable".
The judge said a probation report described Kahle as "unmotivated to address [his] drug use", but she accepted he had changed his view having had "the benefits in the time of custody without the influence of cannabis".
Judge Morris sentenced Kahle to eight and a half months in prison, taking into account his time in custody since his June 25 arrest.
