Possession charges can be treated as a summary or indictable offence depending on various factors. The exception to this is the possession of a personal amount of marijuana (up to 30 g) or hash (up to 1 g), which is treated as a summary offence and carries a maximum penalty of 6 months in jail or a $1,000 fine. Possession of other substances from schedules I and II carry prison sentences of up to 7 years.
Trafficking, production and cultivation offences are much more serious, and can carry jail terms of up to life in prison.
