Justice Gilbert said Housham had a life-long involvement with cannabis and in his 20s suffered a back injury which he self-medicated with cannabis to control the pain.
Housham became involved with gangs and started using methamphetamine a year before his arrest after he was known to be a man who sold cannabis. Housham admitted 12 charges of supplying methamphetamine, three of possessing methamphetamine for supply, four of offering to supply methamphetamine and one charge of conspiring to supply methamphetamine.
All these charges carry a maximum sentence of life imprisonment.
He also admitted three charges of offering to supply cannabis resin, three of offering to supply cannabis and one of possessing cannabis for supply, and a final charge of participating in an organised crime group.
The methamphetamine charges, involving a total of 36g, related to the time period between November 11, 2015 and December 12, 2015, while the cannabis offences happened between October 27, 2015 and December 4, 2015.
Housham was given a 25 per cent discount for the early guilty pleas.
Lawyer Dave Sayes said Housham had participated in drug and alcohol programmes as well as those for anger management while in custody.
On the methamphetamine charges he was sentenced to three years five months' jail, on the cannabis charges 18 months' jail and for participating in a criminal organisation six months' jail, all to be served concurrently.
