Ideally decriminalise but don't legalise - I understand that leaves a reduced ability to control - perhaps decriminalisation requires associated conditions such as rehab, education and no further use within 'X' period. Pursue education programmes (as suggested) to reduce usage, and to deter usage not just until 25 but thereafter. Provide information about how this could work around drug free & safety critical workplaces. People in general, but specifically those working in safety critical workplaces shouldn't have to be exposed to people engaging in this behaviour and it would be disappointing to see usage increase. Smoking cannabis should remain at least as socially unacceptable as smoking is becoming, with the exception of medical usage which should be given greater support where deemed appropriate by suitably qualified medical professionals.
