Dealing the drug ice to schoolchildren would carry a 25-year jail term under a promised suite of offences related to crystal methamphetamine announced by Labor.

Opposition Leader Daniel Andrews said under Labor the new offences would include people who wrote or circulated "cookbooks" on how to make the drug, and nightclub owners and landlords who "turn a blind eye" to dealing and manufacturing on their properties.

Crystal meth trafficking and addiction had "got away from all of us," Mr Andrews told radio station 3AW.

All the new offences would carry a maximum penalty of 20 to 25 years jail.

Other new offences included selling the drug near schools, and using violence or threats of violence to force a person to peddle ice.
