A cross committee group of deputies would engage with the cannabis industry, the law and health to assess the impact of decriminalisation of the Class B drug.
Home Affairs president Marc Leadbeater says the current situation criminalises some for possession while others are able to buy the drug legally, with a prescription, for medicinal use.
He says cannabis is widely used in Guernsey without safeguards.
He has lodged a requete, or request, backed by deputies Gavin St Pier, Charles Parkinson, Tina Bury, Aidan Matthews, Andy Cameron and Alderney representative Alex Snowdon.
They want to set up a working group, with one member of the five principal States committees, to report back by the end of the year on the pros and cons of setting up a licencing framework for cannabis use.
It would consult with medicinal users, the medical establishment, the law and examine other places where government controlled use of the drug is allowed.
Deputy Leadbeater stresses in his requete that the States 'are not being asked to endorse cannabis legalisation. They are being asked to endorse informed decision-making.'
If agreed by States members, the working group would come back with a report and proposals by the end of the year.
